One of the most beautiful freshwater fishes, the Cardinal Tetra does best in a school of it's own species. They prefer acidic water, but will live in just about any water that is clean and pure.
Being difficult to spawn and raise in captivity the Cardinal Tetra is more expensive than its slightly smaller cousin the Neon Tetra. The Cardinal is also a lot more sensitive to pollution.
