About the species

Sciaenochromis ahli is a predatory Lake Malawi haplochromine whose dominant males rank among the most intensely blue cichlids in the lake — a fact that has made the species, and its close relatives, a fixture of the "electric blue" trade for decades. It hunts by ambush along the sand-rock interface of the open water column, well below the shallow reef zone favoured by the mbuna. The name most hobbyists actually know, "electric blue ahli," is a common source of confusion, since the fish most often sold under that label in shops is the closely related Sciaenochromis fryeri rather than true S. ahli.
