Tetra Cardinal

We will be shipping live Fish and coral only on Monday and Tuesday of each week.

Arguably the most popular of the small tetras, the cardinal tetra is similar in appearance to a longtime aquarium favorite, the neon tetra. Cardinal tetras are an active schooling fish and they live well in a peaceful community aquarium. Although they are difficult to breed in captivity, tetras remain a very popular aquarium fish.
