When putting the turtles up for the night last night, I noticed that my male 3-toed is really coloring up. I've only had him about a month now, but his color on his cheeks and more on his beak are really brightning. It's a pretty peach to bright orange color.
I'm sure it's a combination of a better balanced diet, his maturation process, and being around a female. This is the best picture I could get of him. My camera's not the best.
