Description

Vandenberg's pearlfish is a small annual killifish (Rivulidae) from temporary rain pools of the Paraguay and Pilcomayo basins in South America. The species grows to about 5 cm; males are glossy blue with dark crossbars, females inconspicuously brownish. When the pools dry the adults die, but their eggs survive the drought in the mud and hatch with the next rains. It eats small invertebrates and insect larvae. The fish is harmless to humans.
