Please Note: The images shown are typical examples of mature adult fish and not necessarily the exact fish in our current stock. Actual fish coloration can vary due to lineage, location, age, and gender. If you would like photos of the fish currently available, you may request them. Please understand that we may not always be able to provide these promptly due to time constraints, and photographing some fish can be challenging.  Apistogramma macmasteri is a widespread species of apisto with a large variety of localized and man-made colour forms. There are also many similar species that may be misidentified as A. macmasteri; on the flip side, various morphs and locales of macmasteri are often sold as other species, especially A. viejita (true viejita is basically unheard of in the hobby). They are an average sized apisto with males approaching 3" in max length; females stay smaller, around 2". Like most apistos they do well with various peaceful schooling fishes, and are usually more outgoing when some are present.
