More about the species
Description
Occurs in saltwater marshes, tidal creeks and nearby fresh water. A resident intertidal species with homing behavior. Adults are mainly found in saltwater marshes and in tidal creeks. They may leave tide pools if aquatic conditions become inhospitable. They also enter fresh water to a limited extent. Not a seasonal killifish. They breathe air when out of water. Difficult to maintain in aquariums. Introduction has caused the decline of native species and near extinction of Aphanius baeticus in southwestern Spain.
