About the species

Otopharynx lithobates is a small, rock-dwelling cichlid endemic to Lake Malaŵi, named for its habit of frequenting the lake's rocky shores. It is one of the most familiar of all Malaŵi haps in the aquarium hobby, traded for decades as the 'Sulphur-head' or 'Yellow Blaze' Aristochromis: a breeding male is a dark, neon-flecked blue fish capped by a brilliant sulphur-yellow blaze running over the head and dorsal fin. Despite the trade name it is not an Aristochromis at all, but a modest cave-dweller of the sediment-rich rock zone.
