white-ish shell on yellow bellied slider!! help!
hi, my yellow bellied slider's shell is getting white, it looks like its shedding or something but i'm not finding any shell pieces or anything in his water. i put him in the sun regularly like twice or three times a week for a few hours, could it be that? he seems to be healthy, he swims a lot and everything, he doesnt eat much but he was never a big eater and he sleeps regurarly. i live in a mediterranean climate if it helps and its wintery right now, about 20 degrees celcius.. he doesnt seem to be hibernating or anything he just sleeps a little bit more in the mornings thats all.
