Rainwater Killifish (Lucania parva)

Rainwater killifish (Lucania parva) are a small species of killifish native to the east coast, ranging from Cape Cod, Massachusetts through Tampico, Mexico. They have also established several invasive populations outside of their native range. Most common in estuarine environments, this species can tolerate a wide range of salinities from full freshwater through full saltwater. Rainwater killifish are sexual dimorphic when mature with the males sporting a black anterior blotch on the dorsal fin. Breeding males will color up nicely, with their caudal, pelvic, and anal fins often developing red or orange pigmentation. Spawning typically occurs in the spring and summer, with females releasing their eggs on the leaves of aquatic vegetation.  Rainwater killifish are a schooling species and do well when kept in groups, they are often observed schooling with other killifish species. This active species makes for a fun and niche captive with undemanding care requirements. A must have for the
