Comments: 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.
