He's four inches, or maybe one cm over 4 inches. But I know for sure he's at 4 inches. He has a 29 gallon tank. I'm actually upgrading him tomorrow to my new 40 gallon breeder.
He has a new basking light (old one burnt out) that gets quite warm. He seems to be enjoying it, though.
His tank is not heated. I know, I know, he needs a heater. But the only time I worry about him is at night when he doesn't have the light. I'm considering adding a heater but putting it on a timer so it comes on when the light goes off. His water hovers around 74 with this new light, and drops back to 70 or 72 at night (when I get up in the morning, at least).
I feed him ReptoMin. He gets maybe 5 adult sticks 2x a day. Am I overfeeding? He doesn't seem to have too much fat on him...
He's hungry, active, and, except for the shell, a healthy turtle. He swims fine (pretty well, I might add). He basks. He sleeps under water. Half of his water is changed ever week. I haven't changed the filter in who knows how long. I do rinse it as needed, though.
I'm thinking this is nothing to be concerned over, but I thought I would ask anyway.
Here he is:
First up: The slight hole near his shoulder:

It's tiny and is the only one I can find, but it's also slightly concerning to me.
Next: The patches on his shell and the white outline around the scutes. The patches in this picture are in the middle and bottom middle scutes. The lighter patches and splotches.

These are shiny looking in the water, like loose scutes are.
Then we have: The patch on his top right scute. This one is much like the rest.

Finally: The patches on the outer right scutes;

So, what do you say? Should I be concerned? I'm thinking the white outlines could be hard water stains (I do have very hard water....)
