I played around with the unknown chemical the other day, just for fun. I had a tank filled with the same species of fish. Then kept adding the checmical until none of that species were in there. Sometimes it changed fins but not body, sometimes body but not fins and sometimes it changed both. It didn't affect all the fish at the same time. I think it took about 30 applications before I had none of the orginial species left.

Cool! I was looking for ideas for something different than the usual to do, and you just gave me one. Maybe I'll try to figure out a different fin - uh, er - spin to put on it so I wont be plagiarizing.

it turned my greenfin spotanus into an oriental spotanus! no more magicfish of fertility...
