I guess I probably should have clarified, I added that because OP likes the look of the desert ghost and some of the adult deserts I've seen look a lot like the more yellow desert ghosts on WoB and some desert fires I've seen look like the other desert ghosts. So I just meant to warn them about the fertility issues just incase they come across a female desert and think,"oh, hey. This looks alot like that desert ghost I saw on WoB! Wow, and she's cheap and pretty! I think I'll get her for future breeding!"
I am aware that they are different morphs.
