Hi everyone! We've had our tortoise for almost two years. Today I noticed her arms and legs (is that what they're called on a tortoise?!) are white! Her shell has some white spots on it also. It was not like this yesterday. It seemed to happen out of nowhere. We keep her tank at about 80 degrees F, humidity around 60, we have an artificial sun source. She has a mister and heat lamp. I'm reading this could be shell rot, but on her legs also?! Any ideas? I'm worried, wondering if I need to bring her to a vet. She's acting normally, eating and going in her water.
