Thats a good amount of money to spend right now. You also can't be certain that you wil get 10-15 pastels. Something I've learned from breeding snakes is never count your morphs until your eggs hatch. Last year I bred a pied male to a het pied female and got 9 eggs and only one was a pied. Statistaclly is should've gotten 4-5 pieds. There's no gaurantee on what will hatch.
