Description
The X Ray Tetra can be a really good fish for the freshwater fish beginner. These tetras are fairly hardy and should do well in a somewhat broader range of water parameters than other tetras. The X Ray is very peaceful when kept in small schools of 6 or more. Physically, these tetras get to be about 2 inches (5 cm) and they are sometimes called the X-Ray tetra because of its almost transparent body. Look for the signature black stripe across the middle of the dorsal fin.
