I want to get blind cave fish for my 29 gallon tank... but I need help?

Question

I want to get 2-3 for my 29 gallon, but
1. How do I feed them? They're blind!
2. Will they be peaceful?
3. On a scale of 1-10, 10 being very delicate and 1 being as easy as a betta, how easy are they to care for?
4. Any other info I need?

Answer 1

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. The lack of eyes and color have not lessened it's popularity. Active, peaceful and easy to care for, the Blind Cave fish makes an interesting addition to a community tank.

Recently, studies have been conducted to see if eye development could be stimulated. Surprisingly, when lenses from sighted fish were transplanted to the Blind Cave fish, it began to develop an eye. It is hoped that further study of this phenomenon may prove useful in treating blindness in humans.

Habitat/Care
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. Lighting is not a major concern, however it has been reported that the prefer

Diet
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. When planning to spawn them, they should be conditions with feedings of fed live foods.

Breeding
Females are somewhat larger and plumper than males, but otherwise have no distinguishing markings. Prior to spawning the fish should be fed live foods for several days. To stimulate spawning drop the water temperature to 66-68 degrees. The female will scatter up to one hundred eggs throughout the breeding tank.

The eggs should not be moved, as they are sensitive to handling. Fry will hatch within two to three days, and be free swimming before the week is out. Freshly hatched or frozen baby brine shrimp may be fed, as well as commercially prepared fry foods, or very finely crushed flake foods. Interestingly, the developing fry initially have eyes which atrophy as the fish matures.

So now that you have a book that didn't answer your questions...

Blind Cave fish are tetras and very easy to care for. Now, right off the top they get about 3 1/2 inches long so 2-3 will be ok in your 29, but I wouldn't go over about 5 in the tank. they do need space and the size of the bottom of the tank is important for them.

You feed them like you feed other fish, but use sinking food. They can smell the food and find it rather well.

Yes, they are quite peaceful and usually don't bother anything else in the tank at all.

Because they are blind they do have a slightly harder time finding food than other fish. For best results I wouldn't keep them with any other fish but..... If you have other fish in the tank, don't have any other nocturnal feeders or bottom feeders in the tank and feed the cave fish after you turn off the lights and the other fish have settled down for the night. Feed when the roomis rather dark, no other lights on if possible. That will give the cave fish the advantage and allow them to eat without competing for the food. The other info you might need is actually in the post above ;)
