I have had my red eared slider for about 3 weeks now and i have noticed changes in its shell just recently. During the first week I noticed a goldish color on it. Just today I noticed that there was even more gold up the turtles back. I decided to take a picture of it really see how it looks since my turtle does not stay still. Once I took a picture it looked way different with the flash on and I'm worried because I see black spots. Also towards the turtle's tail the scutes look sharp, for lack of a better term. My turtle seems to be eating normal. He does bask for quite some time. I don't have a screen cover, I don't know if that matters. Also I change his water once a week and I do condition the water. We do have a water filter as well. does this look bad to anyone? Should I be worried??
