The Blind Cave Tetra is also known as the Mexican Tetra, Blind Cave Fish or the Silvery Tetra. They are a good beginner’s fish, as they can tolerate great variation in water temperature and quality. The scientific name was originally Anoptichthys jordani, but it is now classified as Astyanax fasciatus mexicanus.
The body is a flesh/silvery color without features and the fins are colorless. The dorsal fin has a broad arch to it. The main feature of the Blind Cave Tetra is an absence of eyes. They are born with eyes, but the sight deteriorates quickly and the eyes become distorted and covered over within a few weeks. They navigate in darkness quite well and have well developed taste buds. The tank should be covered as Blind Cave Tetras will jump when they are stressed. They eat flake foods, freeze dried bloodworms and live brine shrimp.
Temperature: 68 to 86 degrees Fahrenheit Origin: Texas, Mexico
