My turtle has a greenish color around his mouth and it seems to be spreading up his nose. His skin is shedding which I was told is normal but I wanted to check on that too. Does anyone know what this is? Is it something wrong with him and if so, what do I do to fix it? I have had him for about 5 years and his mouth has had a slight green tint for a while but it is a lot darker now and is worrying me.
