Andinoacara stalsbergi

Description

Andinoacara stalsbergi is a species of South American freshwater fish in the family Cichlidae. It was previously included in A. rivulatus, but was described as a separate species in 2009. The specific name honours the Norwegian aquarist Alf Stalsberg who collected the type of this species and who has had a “longstanding commitment to increase the knowledge about cichlid fishes”. A. stalsbergi has scales on the body with light centres and dark edges, and narrow clearly defined white edging to the tail and dorsal fins. This separates it from A. rivulatus where the scale-pattern is reversed, and the fin-edging is gold-orange or less clearly defined white. A. stalsbergi are found in rivers and other freshwater habitats in western Peru from Piura to Ica, while A. rivulatus are found in far northwestern Peru (Tumbes) and western Ecuador. Although the largest officially measured A. stalsbergi only had a standard length of 11.3 cm (4.4 in), it is known to reach a size comparable to A. rivulatus.
