Hmm, now i'm sure someone will correct me if i am wrong, but finding some morphs are difficult and there are by no means as many morphs as ball pythons. I don't personally know of any pages like the ones you use for ball pythons, but that's not to say that they aren't out there.
Morphs are just starting to gain popularity among hognoses. I got into it because there weren't too many morphs out there and it was relatively inexpencive. Now, we are seeing supercondas and all this other stuff that's running into the 10's of thousands and more! I think i's more common with hognoses to have different morph mutations, like high red albino or a pink albino. It also depends what kind of hognose you decide to work with. Most things are done on eastern and western because they are common and when you go for patternless, it doesn't matter if it's a mexican compared to a western. I have my preferences, but that's just me.
Take a look around, it's new so people are coming out with new stuff all the time. There are no cinnamon hognoses, or pinstripe (that i know of) so people are trying new things all the time. Some places forcus on different albino morphs instead of anything else, so it's all on the person, and most of this breeding is on a privatized basis.
