There are dozens of different species of fish known as tetras, in all shapes and sizes. The name tetra comes from Greek for four, which refers to the fish having four fins. Varying kinds of tetras come from South America and West Africa; they tend to be shoaling fish and prefer to live in groups of five or six or more. Most will happily coexist with a range of other community fish, are relatively hardy and easy to feed. Some may even breed, scattering eggs in among your plants. Most prefer softish water with a pH of 6 – 7.5 and temperature around 24 – 27C.
