Hello all, I have acquired a spiny tailed iguana that I'm not sure the actually species of. I would like to know what to expect as far as adult size. I do know of basic care for the general Ctenosaura group, but I'd like to know what to expect as I said. Currently it is in a 40 gallon breeder cage with tile substrate. Basking spot is 108 F. Unsure of humidity as I do not have anything to measure it. He has a half log to bask on, a bowl for greens, and a large bowl for mealworms and superworms. He's eaten a couple supers and a few crickets so far but no greens yet. He's semi-tame, does not bite but a little squirmy. He looks to me like a Mexican spiny-tail (C. Pectinata I think?). Very young if he is, only 13 inches long. Let me know if you can help identify him, and any tips for keeping these iggys would be great!
