Cool Article About Blind Cave Fish

http://news.nationalgeographic.com/n...cave-fish.html

If I had the room I would experiment with this. The gist of the article is that Blind Cave Fish offspring can regain their sight. Read the article for details.

That's amazing!!! I would have NEVER guessed that!!!!! My granny has a few of them in her tank. I wish they would mate! That would be the coolest thing!!!

I think what they mean is ones bred in captivity have eyes at first, but since they are exposed to the light for an extended period of time they keep there eyes to see.

Where wild ones arent exposed to sunlight, so the scales eventually grow over their eyes.

My question is why for so long havent any "eyed" fish been sold? Are they all wild caught? Makes you wonder...

That would be cool to see eyed fish being sold! I had one as a kid but it didnt live very long.

My guess is that they aren't a popular aquarium fish because they don't have the brilliant coloration of some other fish. That really doesn't make sense to me because albino cories and plecs are quite popular. I have to admit that I like them but don't see them all that often. They are an easy fish to breed, though.

What surprises me is that the change can happen that quickly. I would have expected it to take a few generations.

Cories and pleco's clean the tank, that's why they are so popular. To keep algae blooms down and remove unwanted waste. Though they eat more than algae, they'll quickly snap up bloodworms,brine shrimp, and fish eggs (or small fry) and fallen fish flakes.

I used to keep blind cave fish many years ago.
I stopped because they are very destructive to the fins and tails of other fish.
They hitch a ride by clamping down on them.
