Tropheus moorii
An algae-grazing cichlid endemic to Lake Tanganyika. More than 40 geographic colour morphs are known, ranging from dark green to flame red and yellow. Long-term success depends on keeping a group and feeding a vegetable-based diet.
Tropheus moorii is a cichlid endemic to the rocky shores of Lake Tanganyika, reaching about 14.5cm. Isolation between rocky habitats has produced more than 40 colour morphs, from dark green through flame red to yellow. In the wild it grazes filamentous algae on shallow rocks, and in the aquarium the diet should be based on spirulina flakes, blanched spinach and nori, avoiding beefheart and other animal meats. It suits hard alkaline water of pH 8.0-9.5, 8-25 dGH and 23-27C. Conspecific squabbling is constant, so the standard approach is to introduce 20-30 fish at once to spread out the aggression, with 6-10 females per male. Breeding is maternal mouthbrooding: females hold roughly 5-20 eggs for about a month. The IUCN lists the species as Near Threatened.

A single fish needs at least 120x30x30cm (about 108 litres), but since this species is kept in groups a tank of 150x45x45cm or larger is preferable. Use rockwork to break lines of sight while leaving open swimming space.
23-27C, pH 8.0-9.5 and 8-25 dGH: hard, alkaline water matching Lake Tanganyika, kept stable with regular water changes.
Relatively peaceful towards other species but squabbles fiercely with conspecifics. Very active, so it does not suit shy tank mates; Julidochromis, Eretmodus and other Tanganyikan species are safer companions.
Spirulina flakes, blanched spinach and nori form the staple. Live and frozen foods are only a small supplement, and beefheart or other animal meats should not be fed.
Spawning takes place on a rock surface and the female mouthbroods. She carries roughly 5-20 eggs for about a month before releasing the fry; 6-10 females per male is the recommended ratio.
Avoid a protein-heavy, animal-based diet. Colour morphs are tied to locality, and mixing populations from different sites leads to hybridisation, so keepers normally maintain a single locality per tank.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Blunthead Cichlid is 23〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Blunthead Cichlid typically reaches Up to about 14.5cm as an adult. Size may vary depending on care conditions and individual genetics.
Blunthead Cichlid feeds on: Spirulina flakes, blanched spinach, nori and other vegetable matter. Aim for a balanced diet with appropriate feeding frequency.
