This is probably just me being paranoid but Tortellini’s head has been looking a little dry - his tank is at about 75% humidity and his heat mid 80s. I bathe him several times a week and he’s always climbing into his water dish and dunking his head. He burrows a LOT which is what I’m thinking it might be from? I swabbed it with a wet Q-tip but it didn’t seem to make it better. Is this normal/okay?
