I first noticed that it was suddenly hiding when normal it's out and about. Yesterday, it stopped hiding so much but then I noticed a white spot on it that seems to be protruding from it's body and today it seems to be larger. I want to treat it but I have no idea what it is. At first I wondered if it could just be poop, but it seems to be coming out of the side more than the bottom, and I've never seen anything like this on it before. Any help is appreciated.
