Glofish: dyed or not?

Interestingly, when I came home, I noticed that one of my Green glofish died. I noticed a snail munching on it, and I saw what appeared to be some sort of greenish dye being released as it was being eaten. Is the fluorescence produced by production of fluorescent coloring pigments in the fish, or were they dyed? I got these at the local Petsmart btw.

I'm assuming that the green stuff is a pigment of some sort. And interestingly, it made my water slightly green for a while, until the filter got it all. None of my fish have been affected in any way yet though.

Just to add some more information (and save myself some typing), we had a similar thread and conversation a couple days ago here-

Glofish - thoughts?

And no, they are not dyed...they are genetically modified. There is nothing cruel or inhumane about how they are created...they are only offensive to some peoples eyes, lol.

As others have said, they are not dyed. I have seen this too though. When one of my red ones died, I bagged it and froze it to return it on my next trip, since I only had it a few days. By the time I got to the store with it later it was half thawed and the water was full of swirls of red. Also when a fish is dyed, the color fades away, usually completely within just a few months from what I've seen.

They are, I've never seen them in one LFS. Ever.
