The blind cave tetra is the cave-dwelling form of the Mexican tetra (Astyanax mexicanus), from cave systems in northeastern Mexico. It is the same species as the ordinary sighted river fish; isolated cave populations lost their eyes and most of their pigment over many generations, leaving a pale pink-white fish with skin grown over where the eyes would be. Watching one feed is the fastest way to understand that blindness is not the handicap it looks like.
Aquarium care
- Reaches about 9 cm.
- Navigates by lateral line and finds food by smell; it often reaches food before sighted tankmates.
- Lighting is irrelevant to the fish, so light the tank for the plants.
- Shoaling — keep six or more.
- Can be nippy, particularly toward long-finned or slow-moving fish.
- Hardy and adaptable, and takes flake, pellets and frozen food readily.
They suit a robust community with barbs, danios, larger tetras and other fast fish. Avoid keeping them with bettas, angelfish, guppies or any long-finned species, and avoid timid tankmates that will be pushed off the food. Never release aquarium fish into local waterways.
