She was in a 40 or 50 gallon (I can’t remember which it is 
) but I moved her to a 20 gallon quarantine tank when someone suggested she might recover better alone (less stress I think?). She has a UVB and a heat bulb in the basking area, and the water is heated so it doesn’t get too cold.
I will get a photo for you - though there’s nothing much to see. Her eyes are just closed. She usually opens them for a bit right after getting vitamin A drops on them, but then closes them again a little while later.
I had not considered parasites - I’m surprised the vet didn’t say anything about that. Is it common for turtles to have parasite problems? I’ve kept several turtles but never had a sickly one before so this is all very new to me. I’ll look into the parasites for sure.
