About the species

Aulonocara sp. "Walteri" is an UNDESCRIBED peacock cichlid from Lake Malawi — an informal hobby and field designation rather than a validly named species. It belongs to the lake's distinctive radiation of sensory-pore sand-dwellers: peacocks that hover over open or rock-strewn sand and listen, through enlarged pits and canals on the head, for invertebrates stirring in the substrate. "Walteri" is one of several yellow-and-blue forms allied to the Aulonocara stuartgranti complex that have circulated in the trade and in field collectors' notes without ever receiving a formal description. No scientific author, publication year, FishBase record, or IUCN assessment exists for it; everything written here describes a recognised form awaiting taxonomic resolution, and its standing should be read in that light.
