What African cichlids are and where they come from
“African cichlid” is a broad label. Most aquarium fish sold under it come from the Rift Valley lakes, mainly Lake Malawi and Lake Tanganyika, with some from Lake Victoria. These lakes are known for hard, alkaline water, and the fish have adapted to it. Many are colorful and active, and many are also territorial, which shapes almost every decision about how to set up their tank.
Care needs differ between lakes and even between groups from the same lake. This guide covers the general principles. Always check the needs of the specific species you plan to buy.
Are African cichlids easy to care for?
They are often described as beginner-friendly, and some are hardy fish that tolerate a range of conditions. In practice, the difficult part is usually behavior rather than biology. Aggression, overcrowding, and incompatible tank mates cause many of the problems hobbyists run into. A beginner who plans the tank size, rockwork, and stocking ahead of time will generally have a better experience than one who adds fish impulsively.
Tank size and setup
Most guides suggest a tank of roughly 55 gallons as a practical starting point for many African cichlids, and larger tanks are generally easier to manage. Some small species can live in smaller tanks, but a longer tank (more floor space) usually matters more than height because these fish claim territory along the bottom.
Key setup points:
- Rockwork: Build stable stacks with caves and sight breaks so weaker fish can retreat. Secure the rocks so digging cannot topple them, and consider placing rocks on the glass bottom before adding substrate.
- Substrate: Sand or fine gravel is common. Some keepers use crushed coral or aragonite to help keep the water hard and alkaline, though this suits Malawi and Tanganyika setups more than other fish.
- Plants: Many cichlids dig up or eat plants. Hardy species such as anubias attached to rock are sometimes used, but results vary.
- Lid: A cover helps keep fish in and reduces evaporation.
Water parameters and filtration
Rift Valley cichlids generally do best in hard, alkaline water. Commonly cited ranges are a temperature in the mid-70s to low 80s Fahrenheit and a pH above neutral, often around 7.8 to 8.6. Treat these as general guidance and check the needs of your species. Testing your tap water first is wise, because many areas already have hard water suitable for these fish.
Because these fish are messy eaters and are often kept at high densities, strong filtration is important. Many hobbyists choose a filter rated for a larger tank than the one they own, or run more than one filter. Keep up with regular partial water changes, commonly weekly, and test for ammonia, nitrite, and nitrate so that problems are caught early. A new tank needs to be cycled before fish are added.
How many African cichlids to keep together
There is no single number that fits every tank. Mbuna in particular are often kept in fairly dense groups so that aggression is spread across many fish rather than concentrated on one. This only works with enough filtration, water changes, and hiding places. Other groups, such as peacocks or Tanganyikan shell-dwellers, have different needs. See our guides on mbuna care and tank mates and how many red zebras fit a smaller tank for more specific examples.
If you keep a single male of a species, include several females so he does not harass one fish continuously. Avoid mixing fish that look very similar, since males may attack look-alikes.
Choosing species and tank mates
A reliable approach is to keep fish from the same lake and with similar temperament and diet needs. Do not mix Malawi cichlids with fish that require soft, acidic water.
- Mbuna: Rock-dwelling, energetic, and often aggressive. See mbuna cichlid care.
- Peacocks and haplochromines: Typically less aggressive and more dependent on open sand areas. See strawberry peacock tank mates.
- Popular single species: Red zebra cichlids and electric yellow cichlids are commonly kept starter fish.
Feeding: pellets or flakes?
Both can work. Many keepers prefer a quality sinking or floating pellet because it is easy to portion and tends to hold together in the water, while flakes can break up and foul the tank more quickly. Match the food to the fish: many mbuna do better on plant-based, lower-protein foods, while peacocks and other predatory or insectivorous species usually need more protein. Feed small amounts once or twice a day and remove or reduce what is not eaten within a couple of minutes. Overfeeding is a common cause of poor water quality and digestive trouble.
Routine maintenance and health
A basic routine includes weekly partial water changes, filter media rinsed in old tank water (not tap water), and regular water testing. Watch for signs of trouble such as clamped fins, loss of appetite, white spots, bloating, or fish hiding constantly. Bloat is a known concern with some herbivorous cichlids fed a high-protein diet, and our guide to fish bloating symptoms explains how to tell a minor digestive problem from something serious. If you see white spots, see how to treat ich in fish. Quarantine new fish when possible, and consult a vet or an experienced aquarist if a problem persists.
Breeding basics
Many African cichlids breed readily in home aquariums. Mbuna and peacocks are maternal mouthbrooders, meaning the female holds the eggs and fry in her mouth. She may not eat well during this time. If you do not want fry, plan to have a home for them or limit breeding pairs.
Next steps
Once you understand the basics, decide which type of African cichlid fits the tank you can maintain, then read the species-specific guide before buying. Planning the stocking and rockwork first tends to prevent most problems.
