We're going into our second season of breeding Leos and I still can't get a handle on the genetics. Admiteddly I suck with genetics but with Balls I am pretty solid. Leos are a whole different ballgame. I suggest you read up and buy the ones you like and enjoy the looks of. Just like with any other animal you intend to keep and maybe breed, you will be spending a lot of time cleaning/feeding/etc.
