Description: The body of the Nanus is silver with a series of black stripes running horizontally from the back of the head to the tail. There is a horizontal black stripe on the dorsal fin. The belly is pale gray, sometimes slightly amber, with light purple highlights.
It has two pairs of barbels. Females tend to be larger than the males with a plumber body shape when viewed from above.

A few days before spawning, it suddenly becomes very agitated for no apparent reason, swimming in all directions. Both males and females seek each other. Live food and water change with a few degrees drop in temperature triggers the spawning. The female lays her eggs (several dozen) that the male fertilizes. The eggs hatch between 3 and 5 days later at a temperature of 24°C. After a week (3-4 mm), the first spots appear on the body of the fry. The line on the side becomes clear after a month (8 to 10 mm).
