The diamond tetra, Moenkhausia pittieri, is a small freshwater fish of the characin family (family Characidae) of order Characiformes. It is found in and around Lake Valencia in Venezuela, South America. This species exhibits clear sexual dimorphism, with males having much longer dorsal fins than the females. Males also tend to be more brightly coloured, but both sexes are attractive fish and have become popular with aquarists. The dorsal and anal fins are purple and the body is silver. The eye is marked with red above the pupil, and there is a dark band running along the midline of the body. Their common name comes from the bright, iridescent scales along the flanks. Maintenance in aquaria is simple as similar to that of other tetras, although they will not do as well in hard, alkaline water as they do in soft, slightly acidic water filtered through peat. The diamond Tetra is an omnivore. In the wild they will eat whatever they can get, with a preference for animal food, especially Mosquito larvae. In an aquarium they will eat most normal fish foods including flakes. They benefit from a variety of food such as live daphnia or frozen bloodworms.
