About
Rachovia brevis is a small annual killifish found in seasonal pools in Venezuela and Colombia. Despite its modest size, males are vividly coloured with blue-green iridescent scales and orange-edged fins, making them attractive display fish. The species is named for its shorter than average dry incubation period relative to other annuals, though it still requires standard peat-incubation protocols.
