Typical adult size:
Males up to about 15 cm in the lake (up to ~17 cm in aquarium); females up to about 12 cm

Breeding males are black with a creamy white to yellow blaze on the head and upper body. Females and non-breeding individuals lack flank spots and remain silvery

Large aquarium with extensive open swimming space
Aquarium setup:
Open layout with minimal hardscape to maximize swimming space; gentle slopes of sand with limited rock structures are suitable for breeding behavior

Plankton feeder; feeds almost exclusively in the open water column
Breeding:
Maternal mouthbrooder; breeding takes place near intermediate habitats rather than in fully pelagic conditions
Aggression:
Generally peaceful; males become territorial only during the breeding season

A rare member of the so-called “pure utaka”. Difficult to observe in the wild and infrequently collected. Best maintained in spacious aquaria that allow natural schooling and open-water behavior
