I played 2 times..got 4 of 7 first time to help me figure out what works(and what breeds what)...then I just started making $$$ with some $30-$50 fish and started saearching for the magic fish I got the golden guppy first time I played and that is the big money maker. so the only fish I had a hard time searching for was #1.. the reg eggs just wernt giving me one for a long time... to seek out new breeds I used the unknown chemical on preg fish until I would find a new magic fish.(hint make sure your fish is preg when you use the chemical other wise you have no idea how to breed more, if they are preg when they mutate then you will end up with a breeding pair)
