Blind Cave Tetra (Astyanax mexicanus) – Group of 5 fish


Blind Cave Tetra (Astyanax mexicanus), also known as the Mexican Cave Tetra, is an oddball tetra species. These fish are troglomorphic, meaning they are adapted to live in a lightless environment, and are fully missing their eyes! While they are adapted for a dark environment, these fish will still thrive in a standard aquarium setup and will generally do well with similarly sized tankmates.
