The normal coloration of the pindu is solid black, lightening when breeding and even more so if stressed. Both sexes are similar in colour. The body is elongated with a pointed head and nose with a relatively large mouth. It is a relatively robust with a body depth of 30.0-37.0% of its length. The lateral line system on the head is markedly enlarged and a series of dark blotches along the sides is often marked. The maximum size for males is 9.1 cm.
It is a predatory fish and reportedly is also a kleptoparasite on the freshwater crabPotamon africanus. The spawning of the pindu is a rather simple process, a pair of fish leave the main school to spawn directly on to the substrate. They do not construct any sort of scrape or nest and the female lays the eggs, the male to fertilises them and then the females picks them up in her mouth where they are retained for 3–4 weeks.
