Four of my Russians came up today and they all have pink spots under their skin (mostly on the back legs and tail.) One of them (that has severe shell rot damage (he was brought to me that way) has some on his plasstron - in some of the softer spots that are healing. I have never seen this before. The one I just mentioned seems rather weak, but I've watched his weight carefully and he lost less than 5% of his prehibernation weight. Any ideas? (I tried to take pics, but the spots wouldn't show up.)
