|Mexican Blind Cave Tetra
Astyanax fasciatus mexicanus
This fish is similar to minnows in shape. Because there is no pigment in the body, it appears flesh-colored or pale red. Adults reach a length of about 3.5 inches. As the name implies, this species is totally blind. It can, however, move through the water without bumping into other fish or into objects, thanks to an extremely sensitive lateral line.
Distribution and Habitat
This subspecies is found in freshwater pools in caves throughout central Mexico.
The diet consists of animal and plant remains swept into the caves, as well as those included in bat droppings that fall into the water.
