Utaka is a term used for the free-swimming cichlids of Lake Malawi, which in nature inhabit the open water masses, often around underwater reefs or rocky outcrops in deeper parts of the lake. The name 'Utaka' traditionally refers to species from the genera Mchenga and Copadichromis, though it is often used more broadly for non-rock-dwelling species.
Natural Habitat and Setup
Unlike the rock-dwelling Mbuna, Utaka require significant open swimming space. In our aquariums, the focus should be on a large, open sandy area. It is beneficial to place a few large rocks or formations in the background, but it is essential that the fish have room to school and move freely in the middle and upper water layers.
Water Parameters
Like all fish from Lake Malawi, Utaka require stable, alkaline water. The pH should be between 7.8 and 8.6, with a temperature maintained at 24-26°C. Since many Utaka species are more sensitive to poor water quality than their hardier Mbuna cousins, regular water changes and efficient biological filtration are crucial for their well-being.
Diet and Behavior
In the wild, Utaka are planktivores. Their mouths are often specialized to protrude like a tube to suck in small crustaceans. In the aquarium, we should provide a varied diet of small frozen foods like cyclops, brine shrimp, and high-quality fine flakes. They are generally less aggressive than Mbuna, but males can still be territorial towards conspecifics, especially during spawning.
Social Structure and Breeding
Utaka are, like most other Malawi cichlids, maternal mouthbrooders. It is a fascinating process to observe the male in his full breeding colors luring the female to a nesting site in the sand or on a flat stone, after which the female carries the eggs in her mouth until they are ready to fend for themselves.
