 Historically, more distantly related fish were placed in "Chaetodon" too, for resembling them in details – e.g.the common scat "Scatophagus argus", which has a similar shape and size, as well as armored larvae like the Chaetodontidae – or simply because they are colorful, smallish, and unusually-looking – e.g.the quite unrelated paradise fish, as "C. chinensis".
