I just bought some newts like 2 weeks ago and noticed when i brought them home, two of them had little white spots. It was like a piece of there skin was chipped off or something. Now they are getting a bit bigger. One has one on the back of his tail and the other on his knee. The one with with the mark on his knee i saw that his leg is a bit swollen and he barely moves it just drags but he eats a lot and swims pretty good. The one with the mark on his tail does not like the water and does not want to eat, Guessing because he is stressed (They were kept in a tank with moss and just a bowl of water) Would these mark heal by themselves? Or know what should i do? I'm new to having newts
