If you are only going to have one het clown then anything you produce with it will only be 50% possible het clown. You can't sell any of those babies as hets. Then you would have to keep all babies, grow them up, and breed them back to eachother and the het clown to find out which are actually het. That being said, even the ones that are 100% het may not prove out in the first breedings. You're looking at about 6 years or more of breedings before you get the combos you want that are clown and you can prove out at least 2 generations of babies in the process.

If you want clown combos, it would be much easier and make more sense to get co-doms that are 100% het clown as well.

Otherwise, just concentrate on the co-dom combos and breed the het albinos together to try for albinos. Then breed visual albinos to co-doms and get co-dom babies that are 100% het albino.
