*update*

Thank you all so much! Yes, I have moved her to a new water bowl (one that is really meant to be a human bowl, but it works great for her too) and I fill it with a little less water. What looked like the early stages of scale rot on her belly appear to be just little brown dots maybe scruffed from playing around at night because they are barley noticeable and not getting worse. She is also appearing slightly yellow (being a bel) and so might be starting to go into shed.

Thanks again!
