Could be a lot of things. Anything from she's sick to nothing's wrong. Very hard to say based on what you've told us so far, which is probably why there's been a lack of response. Can you give more detail? How old is she? What's her environment? Food? Lighting? Heating? Has anything about her environment changed recently? Mine seems to be much more active in the summer than the winter; for about a month or two this winter, she mostly just laid around not doing much, to the point of not even eating much. Spring came around and she perked right back up and had good appetite again. Seems odd that you'd see something like that at this time of year, but like I said before, it's hard to give any accurate advice without more info...

Sorry about that,
She is almost 2 years old, she lives in a 20 gallon long tank, reptile carpet, 4 hides, feeding on mealworms, no light, under tank heater, Temp on hot side= 90ish, temp on cool side= 70ish, and nothing in her tank has changed. Please respond with any info or ideas. Thanks!
