The way I play it there are only three fish in the common eggs that are healthy enough to cross breed without losing any. The rest are okay if you only breed them with themselves, but they still tend to lose health. There are three more of those. I think there are six body types in all that come randomly in the common eggs. The same goes for fin types. Three are safe every time and three aren't because they are already a cross between two of the others.
I'm taking this game WAY tooo seriously ... and I LOVE it!
I have lots of info on them on my webpage ... but it could ruin the fun if you look at it and learn to much too fast. The fun is in the trying!
