A small, shallow muddy lake with extensive beds of macrophytes.
Geographic distribution:
Apparently endemic to Lake Chilingali, a satellite lake of Lake Malawi
located inland of the town of Nkhotakota. The species seems to occur
throughout the lake.
Typical adult size:
Adult males generally reach about 8–8.5 cm SL (10.5–11.5 cm TL) in nature.
Females are smaller, around 7 cm SL (8.5 cm TL). The largest known
specimen is a paratype of 81.2 mm SL (9.7 cm TL).
Sexual dimorphism:
Males are larger, with longer dorsal, anal and pelvic fins, and in breeding
condition turn brilliant metallic blue-green with orange spots on the
dorsal and caudal fins. Females remain pale with dark horizontal markings
and lack bright coloration.
Recommended aquarium size:
A breeding group of one male with 6–8 females can be maintained in an
aquarium of approximately 250 litres or larger.
Aquarium setup:
Open areas with sand or fine substrate for bower-building are appreciated.
Plants are largely ignored. The species tolerates a wide range of water
conditions (22–28 °C, neutral to slightly alkaline, moderately hard water)
and does not cope well with harassment by aggressive cichlids.
Diet:
Stomach content analyses showed that more than 80% of the diet consists of
Chaoborus larvae and pupae, with additional crustacean zooplankton
(cladocerans) and occasional odonate nymphs. Little detritus was found,
suggesting feeding mainly in the water column.
Breeding:
A maternal mouth-brooder. In captivity, males build mounds from sand or mud
and attract females to spawn nearby. Males become territorial when females
are approaching ripeness, while females do not appear to guard free-
swimming fry.
Aggression:
Generally peaceful and inoffensive towards other species, but breeding
males can be territorial and may harass females or fight with rival males,
especially in confined conditions.
Special notes:
The species appears to be restricted to a very small and environmentally
unstable satellite lake that has undergone major hydrological changes.
