No. You will get whatever codom you breed him to in hets. Ex, if you breed him to a spider you will get 50% spiders and 50% normals all het for hypo. Then breed back the spider het for hypo to a hypo or het hypo to get hypo spiders.
I was thinking he was talking about visual ghosts in the first gen.....
*edit....Read your post wrong...Ugh I need to get off the computer lol*
Any thing you want. If you want to produce more ghosts then another ghost or het. To the pastel you would or should get some pastels 100% het ghost. Thats always a good thing. Even a normal will work then you can get some Hets. Any thing you breed it to all the babies will be 100% het ghost. I really like the Mojave ghosts. I think thats what my mojave will be going to a het ghost male when shes is big enough.
