This young tree snake seems way too skinny to me, but as I don't know anything about this species, I took along my digital camera to post a pic here for expert advice. 
He had a mouthful of this brown mulch-style substrate which I cleaned out the best I could (a couple of bites later - these guys are FAST!), then popped him in a wet snake bag and placed him on the bottom of his cage for 45 minutes before releasing him (for his obvious shed problems). I left him with the thawed mouse they had there, and I intend to return with bigger frozen mice for this guy, as I think he needs bigger prey. They are feeding him 3 to 3 1/2 inch (not counting tail) mice once a week. I know with my kings or ball pythons that would be way too small, but wanted to ask you guys how big a mouse, how many and how often this guy should be fed. Also, did I do everything okay, and is there more I can do for this snake? Thanks!
