Now you know the background of the famous Glofish .
I'm also pretty sure it was an experiment gone wrong as well. I belevie the original intention was for the fish to glow when pollution was present, however, the switch is kind of stuck in the on position.
FWIW, there are now black tetras and tiger barbs which have the same genetic modifiers. I've only seen green (the original color) in the tiger barbs, but a couple of different colors in the tetras.
My daughter loves these things and keeps a school in a 20L in her room. I happen to be a comic book geek, and kind of thought it would be funny to do a tank with the X-Men Marvel Comics decorations they had out at Petco with these fish since they would all be mutants.
