I have a 10 year old female RES in an indoor enclosure. About a month ago, I noticed that her eating had slowed down. Last week, she burried herself in the land portion of her tank and hasn't came out since. I was assuming she was hibernating, but I don't know why, because our home temp stays at 72 and with her basking light and heater for the water her tank is plenty warm. Should I try to dig her up and check on her or just let her do her thing? The girl I adopted her from kept her in a 12 inch by 18 inch plastic bin on top of a refrigerator, so she never was able to dig or hibernate before. I got her last spring, and she is now in a 150 gallon, that is 2/3 water and the rest land.

By the way that is a very nice tank
