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).
Other common names
- Comet Panchax, Rocket Panchax

- Up to 1 1/2in (4cm), but often smaller.
- Peaceful surface swimmer; must not be housed with larger or more boisterous tankmates.
- Livefoods preferred, but other formulations may be accepted.
- Well planted, with some floating plants, a peat substratum, and subdued lighting. Softish, slightly acid water preferred. Temperature range: 73-79°F (23-26°C).
