Thanks for the advice of how to get started. I used the strategy you suggested, worked perfectly, but now I'm not sure how to manage all the different species I have. I was able to track all the fish through the second generation, but that's about 22 different fish. There's no way I can try all the combinations of those fish to find the right ones. I found one of the Magic fish, purely by accident, I just started breeding fish at random. But I'm at a loss to figure out how to play now, besides just relying on luck. My tanks pretty much stay full, every time I sell a fish now, I wonder if I'm selling off a path to a Magic Fish (I know there's more than one path).

Also, is it necessary to keep the Magic Fish once you've found one? I have the Magic Fish of Growth, but I can do without the sped up growing.
