Scientific Name: Tropheus moorii (often referred to as Tropheus cf. moorii)
Geographic Variety: 'Izinga Island' (Tanzania)
Natural Habitat: Found in rocky environments (biotope) along the southeastern coast of Lake Tanganyika.
Adult Size: Approximately 14 cm for males and 12 cm for females.
The 'Izinga Island' variant is part of a group found between Kitango Rocks and Taala Point. Key features include:
Body: Characterized by a yellow spot/patch on the lower part of the body.
Fins: Dominant males typically display a blue dorsal fin.
Females/Subdominants: Females and non-dominant males usually have a yellowish dorsal fin, which may occasionally show hints of blue.
Minimum Tank Size: 400 liters (approx. 100+ gallons) with a length of at least 150 cm.
Water Parameters: * pH: Must be above 7.5 (ideally 7.5–9.5).
Temperature: Constant 25–27°C (never exceed 29°C).
Oxygen: Requires high oxygen levels (achieved via air pumps or strong surface agitation).
Setup: Use fine sand and many rocks to create caves and visual barriers to manage aggression.
Diet: Herbivore. In the wild, they graze on "aufwuchs" (biofilm/algae on rocks). In captivity, high-quality spirulina flakes are recommended. Avoid high-protein foods, as they are prone to "bloat."
Social Structure: Highly territorial and aggressive. It is best to keep them in large groups (15–25 individuals) to distribute aggression, with a ratio of at least 3–4 females per male.
Breeding: Maternal mouthbrooders. Females carry eggs/fry for about 24–26 days. Unlike many other cichlids, Tropheus females may continue to eat while holding fry.
