The Blind Cave Tetra is an interesting aquarium fish with a lively nature. Its most noticeable characteristic is that the fish possesses no eyes, scince it has evolved in caves with no light, it has no need for sight in its natural environment. Interestingly, the fry and young do have eyes, which then dissapear as the fish matures. Despite its lack of vision, the fish is extremely good at navigation and finding food with other senses, and is often better than other sight enabled fish. In the aquarium the fish are lively and active, constantly exploring their surroundings. Although non-aggressive, they do have a habit of nipping fins, so delicate or long finned fish are best avoided as tankmates. In some cases, this habit can cause lots of problems, so it is excluded from the Compatibility Checker. The fish have no special requirements and can be kept in most water conditions, including cooler water.
This fish is excluded from the Compatibility Checker as it is unsuitable for community aquariums or may require expert care.
