Mad science I tell ya. http://glofish.com/ How about a normal zebra fish that now glows under a a black light and also comes in bright red, orange, green and yellow colors??

Now here is where it gets really odd. How did these fish get this way? How about injecting the eggs with Jellyfish DNA!? I am not kidding. Check it out. I did not look at the site long enough to know if there is a price listed on the site but they are $11.99 per fish at my local store. Ouch. But the good thing is that danios (if I remember right) are pretty easy to breed and these fish do pass on their colors.
