The Diamond Tetra is a stockily-built tetra species with a laterally-compressed body. This fish will reach about 2 1/3 inches (6 cm) in length and has a lifespan of about 3 to 6 years in the aquarium. Its attractive, silvery-violet scales feature green and gold or orange iridescents, giving this fish a sparkling appearance. This 'diamond' effect develops as it matures, so while a juvenile, it is rather unremarkable. The Diamond Tetra's eye has a red spot on top.

To get the best out of this fish, set up a biotype tank. For the substrate, use a river sand with some drift wood and twisted roots. Add some dried leaves to the tan, which will stain the water a light brown, and replace the leaves every few weeks. Using dim lighting will develop the tetras' coloring to best effect.
