2manyfish, that is a prob everyone has. Here is what I did when I first started and after I got all my research completed. I kept one of every fin type I had, and bread different combo's keeping a log of each combo and what it produced. This way you will know what fin types need to be bread together to get a certain result. When I was done with fin types, I then kept one kind of each breed, and did the same thing. I was able to luck into all but two magic fish this way. And by doing so I could keep almost all of my breeders in tank one, and a few in tank two and put the prego's in the sale tank. Never ran out of room that way. There are other ways to play, but this is how I did it.
