My turtle sleeps curled up under his dock, between the pole and the glass. WTF? He has a lovely ceramic “turtle hut” that I bought him (which you can see below), and he chooses to sleep under the dock. In fact, I don’t think I’ve ever seen him go in the “hut”. . It’s a “fish hut” now - where the feeder fish go to hide from him. Typical child- buy them a toy and they play with the box.
