The fish will grow in length up to 1.3 inches (3.2 centimeters). It lives in a tropical climate in water with a 6.0 – 8.0 pH, a water hardness of 2 – 25 dGH, and a temperature range of 72 – 83 °F (22 – 28 °C). It feeds on worms, benthic crustaceans, insects, and plant matter. It lays eggs in dense vegetation and adults do not guard the eggs.[1]
Astyanax bimaculatus have been found to follow C. polystictus to eat insects, crustaceans, plant debris and algae that is flushed out by the catfish's foraging.[2]
