In one of my games (I already found all the magic fish and I'm gradually collecting all the species...) I've tried doing some experimenting with the Magic Fish of Mutation (wasp grouper) to see what sort of results I get.

I tried several "batches": random matchings, "perfect fish", even using the grouper itself to impregnate other fish, and so far none produced babies that I didn't expect.

Any ideas? what sort of results do others get?
