Genus:	Sciaenochromis
Type locality:	Mbenji Island, Lake Malawi, Malawi
Biotope:	Most frequently associated with intermediate habitats where rocks and sand occur together and caves are available. It may also hunt over open sand at some distance from rocks and has been observed in vegetated areas near kampango nests.
Geographic distribution:	Lake-wide in Lake Malawi, occurring across reefs and islands.
Typical adult size:	A small to medium-sized cichlid reaching about 115 mm standard length. Males can attain around 15 cm total length, while females remain smaller at about 11 cm total length. In aquaria, individuals may grow to almost 20 cm.
Sexual dimorphism:	Adult males remain conspicuously azure blue even while hunting. Females are dark brown and show about 9–11 darker vertical bars.
Recommended aquarium size:	A minimum aquarium volume of 400 l with a tank length of at least 150 cm is recommended.
Aquarium setup:	Provide ample rockwork and caves as shelter, particularly for females, while also allowing open swimming space. Use fine substrate (sand preferred) so males can excavate spawning bowls.
Diet:	Piscivorous, specializing on very small fishes, especially juveniles of non-mbuna such as silvery utaka. It is recorded stalking prey and employing a rocking, aufwuchs-feeding mimicry before a sudden sideways strike. It also targets juvenile fishes hovering above kampango (Bagrus meridionalis) nests and may hunt at the nest periphery.
Breeding:	Males may display breeding coloration throughout the year. Territoriality is described as uncommon, but when breeding, males may gather and construct bowers of a cave-crater type, typically positioned against a large rock. Spawning usually occurs in seclusion beneath rocks where the male prepares a platform by turning in the sand. Eggs are fertilized outside the female’s mouth; the female then mouthbroods and releases fry after about three weeks.
Aggression:	Generally described as relatively peaceful in aquaria, and clashes between conspecifics are reported to rarely result in casualties. It can be maintained with many Malawi cichlids, including mbuna, but choosing species with similar male breeding coloration is discouraged due to reported hybridization risk.
Special notes:	Often traded as the “Electric Blue” and frequently exported, with many specimens collected around Likoma Island; early shipments reportedly came from Maleri Island and the Cape Maclear area and were sold under older Haplochromis trade names. Southern males may show a whitish head blaze and regional differences in anal-fin hue are noted. The melanin pattern is described as 9–12 vertical bars, with a convex dorsal head profile and a straight, nearly horizontal basal head profile, and the species is distinguished within the genus by its darker overall coloration, including in females. It is frequently confused in aquarium literature with Sciaenochromis ahli.
