Proposed taxonomy

Some authorities have lumped the three families into a single family, Aplocheilidae, a well-established name, chosen for its stability in usage over time, and to avoid the impact of a new name at the family rank for a popular aquarium fish group. Under this proposal, the Aplocheilidae includes three subfamilies: Aplocheilinae for the species from Asia,
