anything co-dom or dominant. pastel, spider, mojave, etc... you'll have to spend a good amount of cash to get a breedable one..... and of course quarantine first so you will have to wait probably til next year to breed. not something you can really do off the bat. I dont have any experience personally breeding but read alot so I think I know but im sure others will chime in as well. and as for the $$ well hopefully you are doing it for the love of the hobby and snakes not just for money.
