Shallow, sediment-rich bays, usually with aquatic vegetation such as Vallisneria;
found at depths of approximately 1–15 m.
Geographic distribution:
Occurs throughout Lake Malawi and also in Lake Malombe.
Typical adult size:
Males up to about 25 cm total length; females approximately 25% smaller.
Sexual dimorphism:
Males grow larger and develop more pronounced coloration during breeding;
females remain smaller and less intensely coloured.
Recommended aquarium size:
Minimum 600 litres; very large footprint strongly recommended.
Aquarium setup:
Large sandy areas planted with aquatic vegetation (preferably Vallisneria);
only a few rocks for structure. Aquarium length at least 180–200 cm.
Diet:
Carnivorous predator; primarily feeds on fish (especially utaka juveniles),
occasionally also on larger invertebrates.
Breeding:
Maternal mouthbrooder. Males dig large spawning craters in sand between vegetation
and defend territories spaced several meters apart. Females brood eggs in the mouth;
very large broods have been recorded in captivity.
Aggression:
Generally peaceful toward similarly sized species, but strongly predatory.
Unsuitable with small fish which will be eaten.
Special notes:
Characterized by a very large, oblique mouth and a single mid-lateral stripe.
Despite its size, it inhabits extremely shallow water.
Vulnerable to overfishing in areas where beach seines are used, and now rare
in parts of its former range.
