I have a 3 yr old eastern, Harvey, that recently has been spending alot of time in his water dish. I originally thought it was mites, but I'm not finding any evidence of them. What worries me is that during winter i usually allow the tank to maintain a colder temperature. Also, i notice that sometimes he'll have his head under water too. I've been searching the forum, but haven't found anything close to this behavior. He is otherwise very healthy. He eats a fuzzy a week, sometimes 2. Sheds well, super friendly. The only thing i can link it to is that it seemed to start around the same time i noticed small ant infestation in his tank. I noticed a small lump near his bum that i assume was an ant bite. It all seems kinda weird. Any help would be appreciated.
