Feeding at night

The thermometer you have there says it's 76 degrees.. that's too cool, and may be your problem. They're less likely to want to eat if they're kept too cool. Temps should be low 80s on the cool side, and low 90s on the warm side.

Yeah i have been toying with the idea of geting a nother undertank heater but my temps vary alot i took this picture after all of the other heating in my room turned off ( i have turtles with huge lights that heat up my whole room) and during the day it is 80-82 but it dose drop at night.

Is there a warm spot that reaches 90-92?

yeah its between 91-95 generaly right now its 93.5
