The sulfurhead aulonocara (Aulonocara maylandi) or sulfurhead peacock is a species of haplochromine cichlid which is endemic to Lake Malawi, it is endemic to Malawi and has only been observed on West Reef (Luwala Reef) and Eccles Reef (Chimwalani Reef). It is threatened by collection for the aquarium trade and this has caused a 70% reduction in numbers. This mouthbrooding species, the eggs are cared for by the females only, is found over mixed sand and rocky area where the hunt small invertebrates in the sand. It closely resembles the blue orchid aulonocara (Aulonocara kandeense) although develops a yellow blaze across its dorsal fin, and in the past these two taxa have been considered to be subspecies.
