Well, this is very odd. Do you have a photograph of the curling on the shell? Maybe your turtle needs a diet change, and definitely a calcium supplement. Sometimes they get tired of eating the same food over and over and over again.
As far as the "lazy" behavior is concerned... I might be going out on a limb here... way far out... But, one of my turtles tends to get upset when I take "her" tank-mate out of the tank for handling. I don't think turtles get depressed like humans, or lonely, but if they've always lived together, they might handle living alone in odd ways. If your turtle had an infection, it would be basking more often than not. Maybe let them hang out together on neutral ground, not in water (less likely to bite and flutter for dominance), and see if the lazy one's "mood" improves.
