He/she also has the pink in between the scutes. I'm hoping that it is just part of growth. I'll definitely keep and eye on it and make sure he/she is getting lots of sun. If there is any change in torties behavior I will definitely have him/her seen. Tonight I gave him/her some hard boiled egg and he gobbled it down. He loved it, can't wait to get some mazuri.
That sort of discoloration is not normal. Pinkness between the scutes in the areas of new growth is normal, but I've never seen that sort of dark smear.
I don't know what it is.
I stand by my prior recommendation of keep an eye on it and make sure the tortoises gets lots of sunshine.
