I recently purchased a Northern BTS. I had read that they're usually pretty active in their tank but since I've gotten mine it almost is always just sitting in one spot with it's eyes closed.
It constantly has it's eyes closed it will open it sometimes but almost always shuts them again right away. It'll usually stay in his hide or burrow and since it's still so new it's afraid of me.
I also have only gotten him to eat one time which was about 5 days ago. I try to feed him but he seems to have no interest. I bought merrick dog food and mixed in some peppers and blue berries.
His tank sits at close to 90 degrees on one side and closer to 80 on the other.
I wasn't sure if this was normal for a new BTS or not can't seem to find and clear answers.
