This species, usually discussed under the name A. sp. Wangenflecken (Cheek-spots), has been in the hobby for over 30 years. It originally was pictured/discussed as A. resticulosa, which it is not. Most dwarf cichlid books have photos and discuss the species. It is a clear/whitewater species from the Ihla de Marajó, a large island at the mouth of the Amazon. It is a relatively easy fish to reproduce. Water values aren't that important as long as extremes are avoided. It isn't as common in the commercial trade as it once was.
