This. Worst case scenario is that you end up finding a really, really good example of one of those three morphs you're interested in that isn't a 100% het hypo, breed your ghost male to it and produce your own hets. The process takes longer, but at least you're guaranteeing you have 100% hets to work with. Either way, it's a win-win since this is a fun hobby.
Well if you buy a butter het ghost or spider het ghost female but only get a butter or a ghost then no, i would not call that a win. I like my money and dont like wasting it on false genetics lol.
