Cichlids are a family of fish that contain some of the most beautiful but belligerent fish freshwater fish keepers can encounter. A great rainbow of these colourful fish comes from a lake in Africa, called Lake Malawi. Making a home for them isn’t always easy, but it is quite rewarding.
First, the aquarium itself needs to be able to hold at least 40 gallons of water. And like most fish, Malawi cichlids are unconcerned with the tank’s actual volume, what is more important is the area of the floor and surface of the tank. The area of the floor is important because this is where fish define territories, and the surface area is important because this is where the water exchanges oxygen and carbon dioxide.
A good filter is essential, and something that can support mild overcrowding is needed. A heater which can keep the tank at a comfortable 75-78 degrees F will mimic the water temperature of their native habitat. And because Lake Malawi is very alkaline, either the water will need to be treated, or crushed coral can be used as the substrate, which will naturally increase the pH levels making the fish feel at home. You will find that using crushed coral is much easier.
Cichlids are accustomed to digging and in turn any plants that are not sturdily anchored will usually find themselves to be dug up and floating around the tank. They may also be eaten, if you introduce the Mbuna fish which is otherwise known as a rock fish. Rocks are the natural habitats of these fish, so providing them with plenty of rocks and rock substitute’s makes the tank an ideal home for the fish. Ideally, the more hiding places, nooks, crannies, tunnels and caves, the better these fish like it. Pieces of plastic piping, broken or whole clean, unused garden pots, and other items can be used if you want to get creative. Many effective cichlid tanks appear to be half-full of rocks.
Even within cichlids from just Lake Malawi, there are two (major) distinctive groups. The first are Mbuna, which are named for their habit of living in and amongst the rocks. They are largely vegetarian, although some species eat more animal protein than others. The second are the Haplochromines, or ‘haps’, which are open water, carnivorous fish. They can, but shouldn’t be mixed in the same tank as they may attack and eat your other fish.
Telling the haps from the Mbuna fish is fairly easy once you’ve seen a few pictures, but telling apart species within each group is extremely difficult. To compound this issue, many of the species easily interbreed in captivity, making it even more difficult to tell them apart. If you are unsure of the fish you currently have within your tank and want to know the species of your fishes, a high-end pet store or an aquarium club is possibly the best way of finding out these details. But pretty if unidentified fish are often available at large chain pet stores.
Modest overcrowding is the key to making Mbuna tanks work. Haps are somewhat less aggressive, and generally do well with fewer fish. Because almost all species are polygynous, there should always be more females than males, or the females will be constantly harassed. It can be hard to tell which is which when the fish are young, but as they get older, you can remove the biggest, brightest, most aggressive fish and be fairly sure you got a male.
Cichlids aren’t easy fish for beginners, but they aren’t impossible, either. Many people find them less frustrating if they have a bit of experience with some of the easier aquarium fish before trying them, but beginners who do their research can be successful, too. But these are definitely not just fish that you can throw in the tank and feed daily, so they are much more suited to people who love learning about their aquatic pets.
