Haplochromis orthostoma

Haplochromis orthostoma is a species of cichlid fish that is endemic to the Lake Kyoga system in Uganda, where only known from Lake Bisina and Lake Nawampassa. Its continued survival in Lake Bisina is questionable as it has not been recorded in recent surveys, but it still survives in Lake Nawampassa. This piscivorous species is peaceful among similar-sized or larger fish, but will rapidly swallow smaller fish with its very large mouth. The largest officially measured specimen was in standard length, although it has been known to reach about in total length.
