My RES is almost 6 years old. She's about 9 inches now. I was gone over Christmas, for a month, and it got severely cold while I was gone. I haven't heated her water before because it doesn't usually get cold enough where I've lived to make a difference, but it's been icy cold this winter. Also, before I left I noticed a small white spot on her shell, but wasn't overly concerned because it was hard and I thought it was a hard water spot. Well, it's gotten bigger since I've been back, and there are a couple other very small spots. I'm pretty sure it's not hard water spots now. Also, I know I've been a bit negligent on her lighting this winter. She was outside over the summer and I've never had a UVB light before with her. I've just let her outside. (I've gotten her one since I've been back home.) I also changed her basking area recently. I built a wood frame around the top. I've had the aquarium filled up to allow the filter to work, and she has managed to get out because of that, falling to the floor. It doesn't look like her shell has cracked, but not sure.
Okay well, to get to the actually question here...she's been rather lethargic lately. I will come into the room and she'll be perched near the bottom with her little eyelids closed. I've been scrubbing her shell with betadine and making her dry out in the tub. I've also added aquarium salt to the water along with frequent water changes. She is still eating, which I suppose is good. And when I come to the tank she will swim around. Does anyone have some ideas as to what's going on exactly? I mean I'm sure my long paragraph up there probably gives a lot of reasons why she's not behaving normally. But I'm unsure of the severity of the situation, but I am concerned, and plan to take her to my vet if she doesn't start improving. I can post some pictures. Looking for advice! Thanks.
