Description: The baby Blind Cave Fish are actually born with eyes, but if the fry are raised in complete darkness as they would be in nature, the eyes will degenerate. Keeping Blind Cave Fish fry tanks dark is very important, as fry raised in normal lighting conditions will have partially to fully developed eyes, a very undesirable trait. This species is very easy to keep.

Diet: Omnivorous - does well with flake foods.
Temperment: Generally a peaceful schooling fish, but may initially nip at other fish while searching for food. This is generally not something to worry about and tends to cease as the tetra becomes familiar with the other fish in the tank. Excellent for community tanks or for people new to the hobby. This fish is best kept in schools of 3 or more.
