The electric blue hap (Sciaenochromis ahli) is a species of cichlid fish endemic to Lake Malawi.

[2] The electric blue hap is a popular aquarium fish due to its colouration.

A semi aggressive fish, only one male is recommended per tank; however if large numbers are kept in a spacious enough environment, it is possible to keep more than one.

Large numbers prevent a single fish from being the target of aggression.

[4] The specific name of this fish honours the German zoologist Ernst Ahl (1898-1945) who originally described this species in 1926 as Haplochromis serranoides but this name had already been used by Charles Tate Regan in 1922, although Regan's name is a synonym of Haplochromis spekii.
