I think you meant altum not autumn...but that is a different species. There are 3 distinct species of angelfish, and all are in our profiles: Pterophyllum scalare (the most common and the one from which all the many tank-raised varieties of angelfish were bred), Pterophyllum altum and Pterophyllum leopoldi. These names/species have had their confusion in the past, all of which is explained in our profiles.
Any fish from the last two species above that are available will be wild caught, or locally raised by an aquarist. Wild-caught P. scalare are available from direct importers but one rarely sees these in the main-line stores.
