What Eats It?
Other larger fish prey on blind cave fish.
Blind cave fish are found in large groups called “schools.”
The blind cave fish has an elaborate courtship during which the male and female make exaggerated movements of the mouth and gills. Presumably the turbulence these movements produce helps the fish locate a partner; male and female swim side-by-side and then mate. Fertilized eggs sink to the bottom where they stick to rocks. Blind cave fish growing within eggs have normally developing eyes early on, but the eyes will start to degenerate within the egg. The fish may be born blind or it may be born with functional eyes which later cloud over and shrink because there is no light in the dark caves and eyesight is not necessary. The lifespan of the blind cave fish is approximately ten years.
