I have had my rhino iguana for almost exactly six months now. When I purchased it, it was 13 inches.

Now it is about 15-16 inches.

Does this look like good prgress to those of you who have raised a few rhinos? If he looks a little stunted or anything, please tell me so. If he looks fine, please tell me so.
Also, doany of you know of any foods that rhinos tend to really enjoy? I'm looking for a food that will assist in taming it. (treats)
