Thank you! I do double check. I measure both the tub and the paper towel on top. The paper towels are usually ~4 degrees cooler. And yes, she is out in the open. I think you are right in the sense that she doesn't feel secure enough. I'll start putting a towel on top. I think with the tank she felt more secure because the foil on top made it dark for her. Thank you so much!! I'll try feeding her later this week. Hopefully that works.
