Traditionally, the Clown Killifish and its closest relatives have been classified as Epiplatys. In 1990, following an earlier paper on the subject, Scheel (see Further Reading) placed Epiplatys within Aplocheilus. Owing to distinct body patterning and unique color distribution on the caudal fin, along with some skeletal and behavioral differences, Scheel also regarded A. annulatus as in a sufficiently “isolated position in Aplocheilus” to warrant its own subgenus, Pseudepiplatys (already considered as a valid genus by some earlier authors).
