Common name/s: Cave Blind Tetra, Mexican Tetra, Blind Cave Fish, Silvery Tetra

Scientific name: Astyanax fasciatus mexicanus

Family: Characidae

Origin: Texas,Mexico, Central America

Maximum size: 3.5" (9cm)

Care: 74-78 F, PH - 6.8 - 7.3, soft water, tank with open space and darker areas (possibly some caves!)

Feeding: They will accept most foods from flakes to live bloodworm.

Sexing and breeding: The females are slightly larger and wider, typical egg-layers. Get a group and allow them to pair, separate parents and feed live foods prior to spawning. Lowering the temperature can help to induce breeding.

Comments: A blind fish, born with eyes but as they grow older skin develops over them. They are a very active fish and fun to watch. They inhabit mostly the mid-level and have a tendency to swim on their side. Can be aggressive and may nip fins. You will often see them searching the floor for left over food.
