A local pet store has started selling ACFs that are similar to the fluorescent tropical fish you sometimes see. I assume that these have been genetically manipulated but I'm having a hard time finding any information on them.

I bought several (they come in blue, green and red) and they are doing fine. They are small and currently in a tank with some guppies. They are quite active and are feeding fine on freeze-dried tubifex and commercial shrimp pellets. I assume they also eat some of the flake food I put in for the guppies.

Does anyone know anything about these or know where I can find out about them? Thanks.
