I found this on eBay:

Are they dyed? How can you tell if fish are dyed or not? I have a feeling they are but I wasn't sure.

They arn't dyed, they have some anenome dna so they flouresce under UV light.

Is that harmful to the fish in any way? Doesn't UV light blind fish?

Sorry about all the questions. I'm just really interested in the different "human engineered" fish.

It isn't harful to the fish per se because the flourescece is written into their genes, and not injected like in dyed fish. UV just describes light in the spectrum just above visible violet. Most consumer grade UV lights don't have the intensity to cause major cell damage.

The only thing about glofish is that they have a patent on them and you cannot breed and sell them. There is nothing wrong with them, they are not harmed in any way, but if they breed in your tank you can't profit from the fry.
