Haplochromis orthostoma is a species of cichlid fish that is endemic to the Lake Kyoga system in Uganda, where only known from Lake Bisina (a medium-sized lake to the east of Lake Kyoga itself)[2] and Lake Nawampassa (a small lake southeast of Lake Kyoga itself and only separated by a thin swamp).[3] Its continued survival in Lake Bisina is questionable as it has not been recorded in recent surveys,[4] but it still survives in Lake Nawampassa.[3] This piscivorous species is peaceful among similar-sized or larger fish, but will rapidly swallow smaller fish with its very large mouth.[3] The largest officially measured specimen was 9.1 cm (3.6 in) in standard length,[2] although it has been known to reach about 18 cm (7.1 in) in total length.[3]
