Labidochromis chisumulae

Labidochromis chisumulae is endemic to Chisumulu Island, one of Lake Malawi's isolated offshore islands. Males display a soft pale blue to whitish-blue colouration with a contrasting dark dorsal fin margin, giving a clean two-tone appearance. Females are brownish-grey. The species is named after its island of origin and is considered one of the more docile Labidochromis.

In the wild, Labidochromis chisumulae occupies the rocky rubble zones around Chisumulu Island, feeding on invertebrates and aufwuchs at moderate depths. Its island isolation has produced a genetically distinct population with a characteristic pale colouration distinct from mainland Labidochromis species.

In the aquarium this species is recommended for hobbyists who want the mbuna experience with somewhat reduced aggression. It pairs well with other island endemics and can be included in a 'Chisumulu biotope' alongside other species from that island. Good water quality and stable chemistry are important for maintaining its distinctive pale colouration.

Water: 24-28°C, pH 7.8-8.5, hard alkaline; excellent filtration and weekly water changes required. Tank: 180L minimum; rocky aquascape replicating Chisumulu Island rubble habitat. Feeding: Spirulina-based pellets and flakes; frozen artemia and mysis as supplement. Breeding: Maternal mouthbrooder; clutches of 8-15 eggs; females should not be over-stressed during incubation. Compatibility: More peaceful than average mbuna; suitable for mixed Malawi community tanks.
