Description

The Carletto's pearlfish is an annual killifish (Rivulidae) from temporary pools and swamps of inland Brazil. The species grows to about 6 cm; the male is brightly coloured with blue, red and yellow spots and marbled fins. When the pools dry up in the dry season the adults die, but their eggs survive in the soil and hatch after the next rains. It eats small invertebrates and insect larvae. The fish is harmless to humans.
