Tropheus and Bloat

Best kept secrets for the hobbyist about the african Cichlid aquarium!


Tropheus and Bloat
By Tom Herman - V.P. CRLCA

Why Tropheus

I have kept Tropheus off and on for some years now and they are not as hard to keep as many of you think. Tropheus will eat most anything and are capable of digesting anything that you feed them.

Many of us have bought Tropheus sometime or another, and after a few weeks one after another will refuse to eat and sit or swim around gasping for oxygen and shortly thereafter die.

For that reason Cichlid hobbyists have given up on trying to keep this beautiful fish, only to hear or see that other hobbyist fish keepers have no problems, "Why?"

Most fish, wild caught or not; carry different types of bacteria, viruses or internal/external parasites. External conditions are easy to treat because they are diagnosed easier and are usually visible.

Treating Bloat

The main culprit for African Cichlid fish losses is the internal (gastrointestinal parasites) termed "bloat". Overfeeding new arrivals in their new environment is a big problem; bringing on constipation. Constipation brings on stress that lowers their Immune system response.

You are cautioned not to overfeed any wild caught fish, especially Tropheus. The following advice is recommended if you acquire wild fish from CRLCA , or any fish that you do not know their origin.

By diagnosing the symptoms of impending "bloat" (i.e. spitting out the food they were eating before with gusto). Flagellate infections in the intestine and organs early, you will have licked half the problem Treat with Metronidazole (Flagyl) by using only one tablet or capsule of 250mg. Do NOT use more because you will likely overdose and burn out their liver and spleen.

Metronidazole is a potent medicine used to combat intestine parasites in domestic and farm animals. Metronidazole does not help against worms. It will treat Hexamita, Spironucleus, Trichomonas, and Protoopalina. You can get this from your local veterinarian, and may also be purchased as Farm Cooperative Stores.

It is probable that some of the fish we acquire will have one or more of the above conditions. Many times we push our luck and add new fish to our tanks and all is well.

How to start a Tropheus tank

Start by setting up a fairly large tank, the more water volume the better. Adjust the PH to above 8.2 (the harder the better) Install a good filtration system i.e. Magnum canister, or filters with Bio-Wheels. Make sure you have a good flow rate, otherwise add a power head with a sponge filter on it with the air tube connected to the venturi letting a good amount of air volume into the tank.

If you like to keep and breed Tropheus, purchase at least min 10 to 20 or more. Make sure the species you acquire are very active and full of life. Obtain a supply of Metronidazole about 20 tabs or capsules each 250 mg. Crush one tab into a small container (dish) add some warm water and mix.

Select a good Spirulina flake and place in the pre-mixed solution letting the flake soaking up the medicine. Make just enough for one feeding. Do not over-soak the flake and keep the flake as large as possible (do not blend or grind, the coarser flake is easier to handle).

Have just enough solution mix so that the flake will soak all the medicated water up . Feed this medicated food once in the morning and once at night (just a little) for six days. After the six-day treatment observe your fish over the next couple of weeks to make sure their feces are solid, not stringy, clear, white or thin. Otherwise repeat treatment again for six days, but one treatment is usually sufficient. You should treat all fish in same tank, and treat all fish, if you are on central system for the same duration even if they look OK.

Any time when you obtain new fish, isolate (Quarantine) them and use this treatment. Avoid costly mistakes. Be always on high alert for any cross-contamination. Always sanitize your nets, so you keep not spreading any disease. There is a Jungle product called "Net Soak" which works very well.

I have heard that some Tropheus breeders feed with no ill effects: Earthworms, Bugs, frozen Brine shrimp, Bloodworm, krill, Plankton, etc. I wonder if Tropheus only eat algae in the Lake, I'll bet they gobble up anything that pass or swims by and are more omnivorous than we suspect.

Best kept secrets for the hobbyist

About the African Cichlid Aquarium!

About the author

Glenn Marshall has been keeping Cichlids as a hobbyist for over 30 years.  He is President of the Canadian Rift Lake Cichlid Association, the foremost buyers’ group in North America with over 500 active members.  Glenn raises both Malawi and Tanganyika cichlids in his 1100 gallons of water.  This article has been written at the urging of the many hobbyist members who want to know the ‘tricks of the trade’. This of course is no substitute for Cichlid books.  Contact http:://cichlidpress.com is the best source for Cichlid publications.  Please feel free to distribute this article for use in your Aquarium club newsletter (appropriate credit is expected).  Your comments are appreciated.  crlca@rogers.com or visit our site at http://www.crlca.com 

Why African Rift Lake Cichlids? 

The beauty and behaviour of the African Rift Lake Cichlid has been a fascination of mine.  This has been reinforced by my recent CRLCA safaris to both lakes with the world renowned Ad Konings over the past four years.  These recent safaris combined with my extensive travels in Africa during the past 15 years have made me a true African Cichlid devotee.  The diversity, beautiful colors and ease of keeping are the three main reasons that these fish have been my favorite type of aquarium fish for so many years.   So why is there so much mythology and misinformation spread about these fish?   Hopefully this article will help you determine that with a little effort and understanding of Cichlid behaviour, these fish will give you years of satisfaction as a hobbyist.

Rumor #1: All African Cichlids are aggressive and killers! 

The Cichlid is a different aquarium fish and much more highly evolved species.   Cichlids are territorial, and not particularly aggressive.  So what do you believe? Often people who have no clue as to the behavior of the Cichlid species usually spread these opinions through the power of the Internet.  While attempting to be helpful, these folks unintentionally publish this misinformation.  Junior hobbyists and others, tend to believe these questionable sources, simply because the information comes up through a search engine enquiry on the Internet. These questionable sources (chat lines, published documents, websites, and fish club newsletters) are a prevalent hotbed of Cichlid misinformation.  Unfortunately of these internet experts do not keep the African cichlids themselves (though this if likely fortunate for the Cichlids). Now please do not misunderstand me, there are many excellent sites which support African Cichlid Research and offer great information.  This article is to make the reader aware that all you read in the printed media or the Internet is not always factual or correct. 

Solution:

First, select a reliable source of written information.  Cichlid Press books are our recommended choice.  Ad Konings is the worlds noted expert on the husbandry and ecology of these fish.  See our website for a list of books written and published by Ad Konings and available at http://www.crlca.com or visit Cichlid Press site at http://www.cichlidpress.com 

With reference to aggression in Cichlids it has been our experience that the secret to keeping Cichlids is to CROWD them and supply great filtration.    The standard rule of thumb for fish in a typical community tank does NOT apply at all to African Cichlids.  Most people do not put enough cichlids in the tank. Sometimes this is a financial consideration, but most of the time it is fish quantities involved in a tank.  Rocks are a must if you want to maintain a natural environment but are not essential to raising the fish.  Rocks create territory, and territory leads to aggression.  Having a fish collection in bare tanks is not usually pleasing to most hobbyists.  Breeders do not seem to have a problem with bare tanks for ease of separating, sexing and netting the fish.  When you choose rocks use large boulders instead of small ones and avoid small cave-like structures whenever possible.  By creating caves, while important to some species, you also create territory, which will cause more skirmishes.  Use tank sizes that replicate the lake conditions (see Cichlid tank sizes) increase aeration and water flow to accommodate the increased biological load.  (See water parameters and filtration comments)

Group of 30+ Tropheus moorii Mibitae (sub-adults)

With no aggression in bare 20-gallon sales tank 

Rule of thumb:  1 sub-adult fish per 1/2 gallon.  1 adult cichlid per 1 gallon. 

 

Rumor #2 African Cichlids are fussy about water parameters! 

There is some truth to this assertion, but usually the misinformation you get is directly related to the source of this information.  South and Central American cichlids are usually soft water cichlids.  These cichlids are more popular in North America (especially in the USA) than the African species (even though they can be more aggressive than their African counterparts).  The popularity comes from the fact they are more easily imported to North America.  The aggression rumor comes from the fact that they are cichlids and African or not they become a catalyst to the aggression rumor. African cichlids are hard water cichlids.  Some other glaring differences are that differentiate the species are that most of the African Rift Lakes are some of the most alkaline lakes in the world.  While many of the rivers and lakes in Central and South America contain much softer water.  While African Cichlids will tolerate softer water, their colors and breeding performance will be minimal. African Cichlids are some of the hardiest and well suited to the home aquarium when the water conditions are right. 

Solution:

Most fish require clean well-filtered water.  African Cichlids are no exception, in fact the more flow and aeration, the better. Water chemistry is crucial.   Most Malawi Cichlids will tolerate PH in the 7.3 ranges, but 8.4 is ideal.  Tanganyika Cichlids like the PH even higher, beyond 9.0   PH can be stabilized by the addition of baking soda to the water. Other buffers for Cichlids are widely available, and work well in low PH water conditions.  Coral sands, limestone and crushed coral in the sump of the system will also improve hardness and to some extent PH.  A water hardness of 300-600 parts per million is best for African Cichlids.  You can raise hardness levels and to some extent, by the addition of rock salt to the water at the rate of 1 tsp per 5 gallons.  Most hobbyists in Southern Ontario, New York State, Ohio, Michigan and Quebec can use the water right out of the tap.  A massive aquifer, called the “Algonquin Aquifer” supplies ground water at Lake Malawi quality and hardness to these locales where the water is pumped out of the aquifer (municipal or private well supply). The abundance of sedimentary rock, limestone in particular increases the hardness of the water.  This is one of the reasons why there are so many Cichlid Associations in these areas.  The other reason is market driven close to good sources of supply.  In the north of Canada, and in areas where granite or igneous rock is prevalent, the PH of the water must be chemically adjusted.  PH, however, is suspected to be as crucial as hardness and conductivity to the husbandry of these fish. There are many great products on the market with Seachem Products http://www.seachem.com being favored by many hobbyists.  There are however many commercial products on the market which are reliable and have a great track record with local hobbyists The price of these products can be a factor in their use.  It is not a cheap proposition to continually having to buffer and adjust low PH water if you have a number of tanks to maintain.  On the next pages are some other ideas to save money. 

Many of these products can be obtained at wholesale bakery goods supply companies or food supply outlets.  Many of the grocery stores have jumbo sizes in these products that can keep costs down as well. 

Some reasonable “grocery store” products - 

 

Household Baking Soda: use this to raise and stabilize PH:

1 tsp per 5 gallons at start-up.  Epsom salts may also be used similar proportion. Cost   $.79 CAD a pound for baking soda (sodium bi-carbonate)

 

 

Water softener Salt - Solar salt (brand) is an excellent choice, as is crystal type water softener salt.

Solar salt, the most expensive, sells for less than $7.00 CAD a 22 Kg. bag  

Solution:

Both types of salt are reasonable alternatives that will work to increase conductivity and improve hardness marginally.  Salt also adds electrolytes and protects the fish slime coat as well as being the first line of defense against many diseases and parasites.  In addition, salt also helps the egg holding ability of many of the mouth-brooding species.  When purchasing salt, it is best to use the crystal rock variety with impurities. This is better than processed salt pellets for water conditioning system use but again your fish will not suffer if you must temporarily use processed salt pellets.

 

 

MYTH: Don’t use Iodized salt  

UNTRUE: You may use iodized salt without any harm to your African Cichlids.  The iodine levels are minimal and actually work against fish goiter in some of the species prone to this condition, i.e. Labidochromis caeruleus.  This is a story based on the marine fish hobby where use of iodine in salt is a different story and can cause problems in water chemistry in the keeping of in those fish.   Cost .89 CAD  

Rumor #3 Only use aquarium salt or marine salt! 

 

$$$ Salt 15 oz $1.39 CAD

Solution:

Actually any salt will do, including the iodized table salt type.  The recommended amount is 1 tsp per 5 gallons at start-up, and some equivalent replacement at water change time.  Marine salt contains a few additional trace elements that really do not justify the higher price.  Marine salt costs as much as $5.00 a pound and has few, if any, benefits to African Cichlids.  

Rumor #4 African Cichlids require huge tanks! 

This is partially true, but the usual pet shop size (30 gallons long) will adequately house most of the species.  When selecting a tank for cichlids, the longer the better however.  African Cichlids tend to congregate in the bottom 2/3 of the tank; so tall tanks are wasted space.  

Solution:

Choose a tank no taller than 24” and, purchase tanks for the length and surface area.  The ideal cichlid aquarium is the 100 long (72 x18x18 inches) or the 125 long (72 x 18 x 24 inches).  The larger sizes allow you to keep some of the bigger species in larger groupings. 

Pet stores in Canada i.e. (Wal-Mart, Pet Paradise, Super Pet, Aquarium Services, and Petland) have the best prices on standard sized tanks.  For specialty sizes or quantity purchases Star Aquarium, a wholesaler in Toronto Canada is reasonable and a quality choice.  Avoid purchasing the corner or odd-sized tank types, especially tall ones.  African Cichlid keeping works best, in long low tanks with a minimum size of 30 gallons and a maximum height of 24”.  Of course the smaller sized tanks can always be used for the rearing of fry. 

Rumor #5   African Cichlids require special filtration and daily water changes! 

The only type of filtration that does not work well with African Cichlids (or with any fish in reality) is the under-gravel type of filtration.  African Cichlids like to dig in the sand; hence, they disturb the under-gravel biological action of the filter.   Most cichlid hobbyists are in two camps.  Central System adherents (more prevalent in Canada), and fluid cartridge / air and sponge filter enthusiasts (mainly in the USA).   

Solution:

Central systems, while more expensive, have the advantage of ease of cleaning and quiet operation.   

One of the best additions to any cichlid tank is a fluidized bed.  This addition eliminates frequent water changes.  The fluidized bed does not filter, but removes all ammonia from the system though nitrifying bacteria action.  The need for water changes is reduced significantly.  The action of a fluidized bed also reduces the spread of disease in the tanks through the action of nitrifying bacteria.  However if an outbreak occurs, the usual practice is to isolate the affected fish, and treat it off system. 

The benefits of a fluidized bed far outweigh any concern about spread of disease.  Often hobbyists add a UV sterilizer in the line when using a central sump type system.  We do this when a wild shipment is received.  We do however keep Tropheus on their own centralized system, as these fish are more sensitive to pathogens especially from Malawi counterparts.

 

Fluidized BED Typical 24” under cabinet model, built by Tom Herman

1 (519) 822.6130 at CRLCA.  This unit will service 800- 1000 gallons.  The surface area covered by the 20 lbs of sand is 2000 square feet. 

Rumor #6   Maintenance and water changes are really a time consuming task with African Cichlids! 

A routine of water changes every two weeks is necessary for removal of ammonia from the system.  Ammonia is the silent killer of all fish, but Tanganyika varieties are especially susceptible.   

Solution:

Water changes reduce the ammonia levels, as does the fluidized bed system.   Products such as ammonia chips will help in temporary situations until the tank is cycled.  It is always a good idea to keep a stock of this product available as well as seasoned water for such an emergency.   These problems are usually created by overfeeding situations and improper frequency of water changes.   Many central systems are fitted with an automatic water change system and overflow eliminating the need for water changes altogether. 

 

 

Ammonia chips: A temporary measure only.  A few chips in your shipping bags will work wonders for long distance transport of fish

Solution:

This is a suggested Maintenance Schedule for systems with or without fluidized beds  

Without a fluidized bed.  Airline systems, Sponge filter or canister single systems, bio-wheels and power filters 

Weekly Maintenance with agitated bottom siphoning 

Malawi Tank 30% of volume

Tanganyika Tank 10% of volume 

Tip #1:  An easy way to conduct water change is to use a few 5-gallon water jugs (two for water removal and two for fresh water addition) Simply siphon off the required water, and add the additional seasoned water.  Dispose of the tank water (remember it contains salt so avoid using in household plants or gardens) and refill with fresh tap water.  If possible, let the water stand overnight to remove the chlorine or add a de-chlorinator.  Do not fill with “softened water”. Be sure to use the tap in the house where you bypass your water softener. 

If you have access to a laundry sink, try using Python’s “No Spill Clean’ N Fill”. It’s a water change system that elimates the “bucket brigade”. Simply, a long hose with switch, faucet pump, adapters, etc. Well worth the price ($70/50ft hose) to make water changes less work especially when you cannot have an automatic water change system due to space & separate tank set-up.  BUT be sure to add a de-chlorinator as you re-fill the tank!

De-chlorinators:

Jungle Products, Hagen products and others all

make acceptable water chlorine and ammonia removal products 

Special Note for Ontario Aquarists:

Since the E-coli tragedy at Walkerton, Ontario, the Ontario Ministry of the environment has legislated chlorine levels in municipal water supplies at four times the pre-Walkerton level in all Ontario Municipalities.  This additional use of chlorine and chloramines by your Municipality now are at levels that can be toxic for your fish.  De-chlorinated or seasoned water only should be added to your tanks!  Water can be easily seasoned by rough agitation, exposure to bright sunlight or 24 hour settling if additives are unavailable. 

Water changes with a fluidized bed. 

Twice month maintenance with “quick” bottom siphoning. 

Malawi Tank 20% of volume

Tanganyika Tank 15-10% of volume 

Tip # 2: Due to the more stable (less inflow or outflow) water conditions in Lake Tanganyika, the fish are less resilient to frequent water changes.   The PH in Lake Tanganyika is nearly 100 times higher than that of Lake Malawi.  Hence fewer changes with less volume water changes for a Tanganyika set-up are suggested. 

Tip # 3:  It is important not to clean the tank to sterile conditions with a fluidized bed system.  Some anaerobic bacteria are necessary for the optimum running of the fluidized bed system.  In short, the tanks do not require as frequent maintenance, beyond the usual checking of heaters, and glass cleaning.  The sump area should have a layer of detritus and should not be pristine and clean. 

Tip #4:  Seeding the fluidized bed and cycling the tank is important for the proper maintenance of this closed system such as a freshwater tank. 

 

Septo Bac is a powdered pre-measured bacterium in 1 oz packages. One dry ounce will cycle a 150-gallon tank in a few days.   Cost $3.49 CAD for 12 packages versus considerably more for a bottle of tank cycling products or other pet store products.  The product contains the same aerobic bacteria but Septo Bac is more concentrated and can cycle 10 x 150 gallon tanks.  In a pinch human urine will also help cycle a tank. Only a few ounces will do the job. 

Rumor #7 African Cichlids Eat Aquarium Plants! 

This is a fact!  Most African Cichlids are herbivores and love this expensive lunch.

Solution:

 If you must have plants in your tank, then opt for the plastic type.  If you have African Cichlids in a planted tank, you likely have more plants in your tank than in their natural habitat.  Cichlids are rock-congregating fish.  While some aquarists require the beauty of plants, they are not endemic to the African Cichlid habitat.  Our suggestion is to forget about plants and get a plant-like background for your tank, if you must confuse Mother Nature. 

Rumor #8 You require a Ph.D. in chemistry to raise African Cichlids! 

Really nothing could be further from the truth.  Might be true for marine cold water and tropical fish setups but not Cichlids. 

Solution: 

The simple parameters given earlier in the article, if followed, will help you successfully keep these wonderful fish easily even the more difficult species.  PH is the key to raising healthy cichlids!   

Simply stated, the three keys ingredients are good wild caught cichlids, hard water with strong flow and rock salt.  That is it.  All the rest is really window dressing! 

 

Rumor #9 African Cichlids (especially wild and pond-raised are disease ridden) requiring special medication and handling!  

Almost the reverse is true!  When wild fish are shipped from Africa they undergo some transportation stress but are normally disease free. 

Solution:

 At the CRLCA we are experts at conditioning the newly arrived fish.   Under conditions of stress, the arriving fish are more susceptible to the diseases carried by your resident fish.   A proper conditioning time is necessary, as well as careful adjustment of the PH to reduce a condition called PH shock.  PH shock is the change in PH in the bags during the export process.  

Technically, all fish in a closed aquarium system are disease carriers and to label wild, pond bred, tank raised or line bred, as the culprit or as being healthier is contrary to the principles of successful aquaculture. 

Suggestions when you feel your fish are stressed or diseased- 

Aquarium fish have a limited life span.  Most Cichlids will live 4-5 years. Wild Cichlids are never exposed to the chemicals we tend to use in our tanks often have a shorter life span but their offspring are often have more longevity.   

Solution:

You are advised to use all medicines with care.  Listed following are some of the treatments available from your veterinarian or farm supply retailer.  ALL antibiotics should be used with care.  We do not endorse any of these products, but we use them when necessary in the situations listed below.  But honestly you are much better off using “rock salt” for most of the conditions you will encounter with your Cichlids.  Just like humans, fish develop resistance to antibiotics overuse. 

Here are some typical remedies we use at the CRLCA depot: 

Tip #1 Rock SALT- 

90% of the time this is all that is required. 

 

Tip #2 For the other 10% of the time:

 

Use of Antibiotics: It is important if you must use antibiotics or other medicines, to use water-soluble antibiotics for treatment.  You are best to use these under veterinary care and only when pathologists have identified the disease symptoms correctly. 

ESPECIALLY in the Summer Months, WATCH for Fungus and Fin rot! 

Tip #3: When water temperature rises above 85 degrees, as it can do in the summer months, fungus can be a problem.    

Solution: The best treatment is rock SALT as well as some commercial products on the market. Consult your veterinarian or local pet shop.

 

 

Fungus Eliminator:

Works well in the early stages initially but;

Tip: Salt dip- bath treatment will work equally as well.

Other frequently used chemicals and additives: 

What about shipping adult fish to other hobbyists?

 Solution:

For shipping and packing of Cichlids we have had success with HYPNO fish calmer. This works well for the shipping of larger cichlids, or if you must transport Cichlids long distances.  The fish calmer slows respiration and oxygen use during prolonged periods in the fish bags.  The rule of thumb is use the fish calmer and ammonia chips for these longer journeys.

 

Tip #6: When filling the fish bags for shipping or auctions use only, 1/5th water 4/5th oxygen/air.

 

Jungle Products’ Hypno fish calmer:

 Is the industry standard in fish calmer products? 

Tip #7:  Never use Hypno or other fish calmer with catfish.  It is lethal!  

If you cannot get Hypno, you can safely use Jungle Lab’s “Bag Buddies”.    It’s the first water conditioner with fish calmer that comes in easy-to-use, mess free tablets. It protects fish by reducing stress, promoting slime coat, removing chlorine and chloramines, neutralizing harmful metals and adding beneficial electrolytes. Also contains fish calmer to further reduce fish stress and adds oxygen as well. Use 1 tablet in fish bag water (fresh or saltwater) per 1 gallon of water added AFTER fish have been placed in bag. 

Rumor #10 Cichlids are fussy eaters and require special  foods! 

Cichlids are opportunistic feeders.  They will do much better on higher quality food.  They eat almost anything.  When we import wild cichlids people are often amazed at the smaller sizes and condition of these fish.  This is due to the lack of food available in both Lakes the competition for food and space.

Solution:

Most Cichlids are omnivores; they eat both vegetable and animal matter.   As a rule of thumb, a flake with a higher proportion of vegetable matter works best.  A mixed flake from a reliable manufacturer is your best choice. 

Live foods such as brine shrimp, glass worms and earthworms will be eaten readily.  For the herbivores, zucchini and romaine leaf lettuce tied to a rock with an elastic band will be eaten with gusto.  The lettuce and zucchini should be used raw. Try Organic Spinach as well.  Members of the Zebra family love it as does Bushy, Bristle & Royal Pleco’s. Members have literally “saved” Royals by feeding organic spinach to them when they arrive in poor condition.  Zucchini can be cut up and frozen and later thawed for use in the Cichlid tank.  Cichlids do very well on Spirulina foods, but this is not a whole diet and should not be used exclusively. 

You should feed with a variety of high quality foods.  At the CRLCA we provide foods from manufacturers such as Omega Sea and Exotic Tropicals to our members in bulk.  This saves our members considerably over the smaller package size.  We have general African cichlid flake, Veggie flake, high protein Fry flake, Spirulina and Krill.  We also use a Vegetation pellet for the larger fish.  We also regularly feed our insectivores and omnivores popcorn shrimp and earthworms.  All Cichlids will also feed on fry and even herbivores will eat fry. 

Tip #1: When feeding earthworms, ensure that you dig these from an area of your lawn or garden that you do not use pesticides or herbicides.  A good source for earthworms is your local bait supply shop.

Tip #2: Feed wild caught cichlids sparingly during the first few weeks of captivity.  Overfeeding of any cichlid is an open invitation to disease and bloat. At CRLCA we feed our fish once a day an amount they can consume in 5 minutes.  Excess food is removed from the tanks.  Cichlid fry are fed twice a day to ensure proper nutrition and growth.  Introduce new foodstuffs gradually to the tank. 

 

Rumor #11 It is complicated to set-up a Cichlid Tank!

(New or used) 

Here is the procedure to set up a Cichlid tank of any size or to cycle a new or existing tank- 

  1. Acquire the tank, and make sure it is long and not too deep. LEVEL the tank.
  2. Clean the tank thoroughly; if currently in use make sure you bleach the tank with household bleach.  If the tank has had other fish in it, then sterilize the entire system.  Add 1/3 cup of bleach per 100 gallons and operate the system overnight.   Drain all the water and add new water to the system, drain and add new water a second time and bring the tank to proper temperature. 
  3. Test the water using a pool chlorine test kit.
  4. Recommended water temperatures:  Malawi tank 77-81 degrees Fahrenheit, Tanganyika Tank 79-84 degrees Fahrenheit.
  5. Add salt and baking soda or other buffers, as per suggestions this article.
  6. Cycle the tank using Septo Bac (or other off-the-shelf products).
  7. Ensure filtration is adequate and strong flow.  Treat the water for chlorine contaminants.
  8. Add rocks, sand (silica sand is the best and most reasonable) and tank decorations.  Weathered limestone is ideal for building the hardness content of the water as well as typical of the type of rock found in both Lakes.  Avoid sharp rocks, and those such as industrial glass and lava rock.  Cichlids often damage themselves on this rock, as they tend to be highly active.
  9. Add fish at days 3-5 and begin water changes even though you may have a fluidized bed on the system.  It will take about a month for the fluidized bed to get to maximum efficiency.  
  10. Do not float the fish bags in the tank.  Instead drip tank water or pour small amounts of new water into the bags. Gently net or lift the fish into the new tank once you have equalized the PH through dripping.  Sterilize all equipment with a light solution of bleach and water.
  11. DO NOT use a seeded filter from another tank.  Do not use carbon filters in your Cichlid tank unless you temporarily want to remove colors or medicines from the water.
  12. If you are planning a Tropheus colony, a sterile environment including a ONE NET-ONE TANK policy for this colony is a must.  Tropheus have little resistance to many bacterial infections due to their long intestinal tract.  NEVER mix Tropheus species with Malawi Cichlids.  Tropheus colonies do best on their own, but will tolerate some of the open water species in their tank.  Most Tropheus hobbyists do not keep Tropheus in a community tank setting. 
  13.  Monitor your new tank closely for the first few weeks or so for signs of ammonia build up.  (Lethargy, clamped fins)  Do water changes regularly for the first month on a more frequent basis.
  14. ENJOY the fish in the natural habitat that you have now created!
