Depends on how far your willing to go. If you get a female you'll have to first produce hets then breed them back to get a chance at spider pieds. You'll be a few years away. If you want to produce more pieds id say get a female, feed her up and get a male het pied and get 50%(theor). takes time to get recessives to mix. Thats why there arent so many and they usually come from breeders with larger stock.
