X-Ray Tetra
Pristella maxillaris
Family: Characidae
The X-ray tetra (also called the pristella tetra) has a nearly transparent body through which the spine and organs are clearly visible — hence the name. Its dorsal and anal fins are boldly banded in black, white, and yellow. It is an extraordinarily adaptable species that tolerates both soft acidic and hard alkaline water, making it one of the hardiest tetras available.
