It has a pronounced dark stripe along the length of the body. The general color of the body is light, tending towards yellow. Its eyes are gold. It will grow in length up to 5.4 centimetres (2.1 inches).
Range & habitat
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 20–23 °C (68–73 °F). It feeds on worms, benthic crustaceans, insects, and plant matter. It lays eggs in dense vegetation, and adults do not guard the eggs.
