Sciaenochromis fryeri, commonly known as the Ahli Cichlid or Electric Blue Hap, is a stunningly beautiful and popular freshwater fish endemic to Lake Malawi in East Africa. Males are renowned for their brilliant metallic blue coloration, which intensifies with age and during breeding. Females are typically duller, exhibiting a silvery-grey to brownish coloration, often with faint vertical bars. This species is a piscivore, preying on smaller fish in its natural habitat. It is a maternal mouthbrooder, with the female carrying the eggs and fry in her mouth for protection.

Fin Edging
Males often have distinct white or yellow margins on their dorsal, caudal, and anal fins, which can help differentiate them from other blue cichlids.
Egg Spots
The presence of prominent yellow or orange egg spots on the anal fin of males is a key characteristic of many mouthbrooding cichlids, including S. fryeri.
