What were the parents? Desert ghost is recessive, so unless both parents were at least het for it, then there is no chance. Im more familiar with DG as its own morph than when its mixed with things, so phenotypically I cant help much. But finding out the lineage to see if its even possible is a good first step.
I feel safe enough saying no, shes probably not dg. Really the only reason that was of interest is cuz it could potentially maoe her more valuable as a breeder. But the plan is for her to pair to kane, as hes a visual pied, and i wanted pastel and yb in that potential offspring list.
