I need to know how to get a twin-fin spotanus. I have all 7 magic fish and have figured out how to breed the others to get what I want, but I cannot manage to get a twin-fin spotanus. I have tried breeding the spotanus to get all the fin types and then buying the unknown chemical to mutate them, but didn't get a twin-fin. I have purchased fish eggs a number of times, but never get the twin-fin spotanus. Since you can only get a spot from a spot and a twin-fin from a twin-fin, how the heck can I get a twin-fin spot??
