So after being a nice bright orange color for a while, Kim is kind of a pastel color now when she isn't dark brown with lots of stress marks. She has squinty eyes sometimes. I have a thermometer with a probe and can raise/lower the lamps as needed to manipulate the temp. I figured she might be too hot (cus of the squinty eyes and brownish color) but even though I've raised the lamp a lot higher (and therefore lowered the temp) she still has stress marks. The UVB I have is the coil reptisun 10.0, have a 20 gallon tank, and a 75 watt (tight beam) heating bulb. Anything I can do to make her happy again? Is she cold?
