Well I let her water temp drop a bit (68-70) and she's been basking a lot more!

I think her 'heat' bulb just isn't cutting it for her, but I'll get a new one and see if she will bask with better water temps too. I've been continuing my research and I guess I was off on her age, sounds like she's closer to 4-5 years old, and we noticed that the built up scutes around her edges account for about 1/2" of her length. I'm hoping to find some good deals this weekend and get her set up real nice and see if we can't get her back to health. I'm a little worried that if she is close to 5, I should be providing her a nest box here soon. Is that something that she should have access to 24/7/365? I'm assuming so. She seems to be warming up to us slowly. She's used to being kept secluded in a dark basement room, so my hyperactive house seems to be a lot for her to take in, but she's definitely been basking more and freaking out less about being 'caught' basking. I can almost approach her directly now before she slides back into the water. Overall I think she's adjusting well and I can't wait to see these scutes start dropping off and give her some relief!
Oh, I was also wondering if dubia roaches would be ok for her? I know they're edible and she will likely eat them, but is there anything I should be concerned about with using them instead of/in addition to crickets? She's protesting veggies, gorges on pellets and freeze dried stuff, I haven't tried anything live for her yet, but I hear she takes crickets and guppies with enthusiasm. I'm planning to try some of the aquatic plants and see if she'll take those over veggies. But I was thinking about raising some dubia and wanted to check to make sure they're ok since I can't find much info on feeding them to RES.
