Both species can be kept in a community aquarium with other small, peaceful fish, However, like most Tetras they should always be kept in schools, preferably in a well aquascaped planted tank. Few things are as stunning as a large school of Neon or Cardinal Tetras.
Have you kept Neon Tetras? If so, share your owner experiences with others. For tips on choosing Tetras, watch this helpful video about different types of Tetras.
