Where does a species start, where does the location variant end? This question is really difficult to answer for some groups of fish, e.g. killies and cichlids from Lake Malawi and Lake Tanganyika. In the case of Pseudotropheus sp. “Acei” from Lake Malawi, the species is not described scientifically. Mostly the light blue, yellow-fin “Acei” from the area around Msuli is in trade at the moment. (https://www.aquariumglaser.de/en/fish-archives/pseudotropheus-sp-acei-2/). But the “White Tail” from the area around Ngara has been swimming in the enthusiasts’ basins for a longer time, since about 30 years. It is very dark, often almost black, to which the white caudal fin and the other light-coloured fin elements contrast wonderfully.
Like all “Aceis”, the “White Tail” is a hardly aggressive animal; in nature swarms with thousands of individuals have been seen. This species does not form territories. In the lake the fish feed primarily on algae, which they graze on trees that have fallen into the water. In nature these cichlids grow to about 12 cm (males) and 10 cm (females) in length, but in the aquarium they can become considerably larger. One should not feed these fish with a high protein diet, then they will remain more graceful and more colourful.
Like all cichlids from Lake Malawi the “Acei” also requires a pH-value above 8; otherwise the care is completely problem-free. Whether you keep more males or more females or even just groups of males is ultimately a matter of taste. But less than 5 individuals should not be kept in the “Acei”, otherwise the species-specific behaviour will not come into effect.
