I posted a few weeks ago on how my one three-toed was seeking the coolest part of the tank and eating little. Well, fixed that by adding more light.
Just in the past week or two, my aquatics (one midland painted, one red-eared slider) are less active, eating less, but they still occasionally bask (but maybe not quite as muhc). I assume they are not sick - is it likely the amount of light per day is causing the behavior change?
Other years near winter like now, my turtle(s) were in a 30" by 12" tanks, and the heat lamp and UV lamp, I assume, made a larger percentage of the area used by the turtle to be brightened (with the smaller tank I had little or no change in behavior as autumn and winter came along). I have the same heat and UV lamps now, but the percentage of the new 48" by 18" new tank lit up is not nearly as much as before.
Just today I added an incandescent light.... maybe that will make the difference
