So I got my Russian tortoise about a week and a half ago and at first he was very timid, dehydrated, and not eating but then after a few days of hand feeding and soaking daily, he seemed to be doing really well! He was active, he liked to go outside, and just seemed overall healthy. But then about 2 or three days ago he seemed to not be doing as well. Now he seems to just lay under his heat lamp, and from what I can tell from his food amounts he isn't eating too much. We went to the vet a few days after I got him and he said that he is perfectly healthy except he is a little dehydrated and needs to gain some weight so he can eat as much as he wants. Is something wrong with him? Or am I just being overly cautious?
