Why have you not went to a vet??? Looks awful skinny to me. I don't believe ast shed the scutes like a res, Ive had a cst for going on 6 years and he's never shed a scute before. If that were my turtle he would have seen a vet a long time ago. Looks an awful lot like she'll rot to me. Needs to see a vet asap. Get rid of the goldfishes for food, they are no good for a turtle, get some cheap steaks, pork, chicken, shrimp.Word to the wise. Goldfish are garbage fish as far as nutrition goes. To compound the problem they also contain Thiaminase which is an enzyme that blocks the absorbtion of B1. This can lead to neurological problems and death. Goldfish also usually contain parasites.
