My turt is constantly getting algea on her shell, is this harmful? Also, the shell is rather dark. I have had her for about 4 years, and I'm not sure how her shell is supposed to look. Is it supposed to be completely smooth? Also, I know they shed scutes, but one of the scutes around the bottom is rather soft and when you press on it, you can see water bubbles in it. Is this normal? Any info would be helpful.
