Cynolebias constanciae, also known as the pearlfish or tropical killifish, is a species of fish in the Aplocheilidae family endemic to Brazil. The name "pearlfish" comes from its long fins with elongated rays and the pearl-like markings decorating its body. It can reach sizes of up to 6 centimetres (2.4 in) TL in the wild and can live for about 2 years.[2][3]
