Care guide

The Malawi eyebiter reaches about 25 cm standard length and is a distinctive predator endemic to Lake Malawi. Its body is strongly laterally compressed — the specific name compressiceps means 'compressed head' — and it has a large mouth that allows it to swallow fish up to 12 cm long. A tank with a base of 150 by 37.5 cm (about 250 L) suits a small group of one male with several females. Temperature of 23–28 °C with pH 7.5–8.8 and hard, alkaline water reflect the lake's conditions. The aquarium should feature piles of rocks forming caves, open swimming space, and a sandy substrate; planting with Vallisneria in dense patches mimics natural habitat. Diet is piscivorous: whole or chopped prawns, mussel, cockle, and lancefish, offered as dead foods once trained. It is peaceful toward fish too large to eat — avoid tankmates under 12 cm. Males are more colourful with blue sheen and orange-red fin highlights, and become territorial only during spawning. Several females per male spreads aggression. The species can be trained to accept pellets over time.
