The blue corydoras has a specific name, nattereri, which honours Franz Steindachner's fellow Austrian, the naturalist and explorer Johann Natterer, who collected the holotype of this species.[3]

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).[citation needed]
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.[citation needed]
