Blind Cave Tetra

The Blind Cave Tetra (Astyanax mexicanus) is a fascinating freshwater fish, known for its eyeless appearance and pale, silvery-pink body. Native to the dark, subterranean caves of Mexico, this unique tetra has evolved to navigate without eyesight, relying instead on an enhanced lateral line system to detect vibrations and changes in water flow.

Despite its lack of eyes, the Blind Cave Tetra is an active and social species, best kept in schools of six or more to encourage natural behavior. It is hardy, adaptable, and well-suited to community aquariums, thriving in a variety of water conditions. Their playful nature and constant movement make them a great addition to both beginner and experienced aquarists’ tanks.
