A popular and easily recognizable Pseudotropheus demasoni is a favorite of Lake Malawi mbuna aficionados. The well defined black and blue bars of both males and females make them an attractive fish. Originally described by Ad Konings in 1994 and named after Laif DeMason.

Don't let the small size of Pseudotropheus demasoni fool you. While the largest males only reach about 4 inches, these dwarf mbuna are very aggressive and won't hesitate to tangle with larger fish. Care should be taken to ensure that tankmates are not only compatible in aggression levels, but also in dietary requirements. P. demasoni is a herbivore and feeding them an unsuitable diet could result result in bloat. P. demasoni is best kept in large groups so that aggression can be spread out and no individual will be singled out. Groups on one male to 3 or 4 females are recommended.
