Hi. I'm really worried about my Russian. she isn't eating and isn't being very active. I have a heating lamp and a UVB lamp in her tank. It's usually about 85-90 in her basking area and in the 70s away from the basking area. She stays buried in her rock (I call it her cave). I soak her for 15 minutes every week. Does anyone know what I'm doing wrong and why she isn't eating or being active? ( I give her a mix of Spinach, Kal Sping mix and other greens)
