General Information:	Easily the most novel fish commonly available today, the Blind Cave fish is named for what it lacks - eyes. Although totally devoid of eyes, they have an uncanny ability to navigate adeptly, apparently by bouncing sound waves off objects around them. Originating from deep caves in Mexico, where the lack of light and predators has made vision un-necessary. Eyes are not the only feature this fish lacks, this unique fish is also without pigmentation, taking on a pink hue from the blood vessels beneath the skin.
Tank Requirements:	See Minimum Tank Volume and Minimum Tank Size above
Diet Requirements:	Blind Cave fish are as easy to feed as they are to provide a habitat for. They will consume any food offered, including flake, freeze-dried, frozen, and live foods. For optimum health they should be fed a varied diet.
Compatibility:	Most tetras
Recommendations:	Water parameters are not critical for this fish, and it will tolerate a range of conditions from soft acidic to hard alkaline water. Likewise, water temperature is not critical and may range from the 60's to the 80's. Because they are an active swimmer, ample open space in which to swim is welcomed.
Common Problems:
Similar Species:	Tetras
Sexing:	Females are somewhat larger and plumper than males, but otherwise have no distinguishing markings.
Breeding:	Females are somewhat larger and plumper than males, but otherwise have no distinguishing markings.
