Hi, so I recently bought a het axanthic BP, and am having trouble keeping the tank warm. Right now the ambient temp is 70 and the hot spot is at 84. I should be getting a larger watt ceramic heater in the mail today so I hope that will solve this problem. However, my BP keeps moving to the cold side and hiding under the log I put there. When I wake up in the morning I go in her tank to spot clean and usually bring her out for a minute, then put her back in on the warm side. She'll slide into the cave there, but then a little later I'll notice she moved back underneath the log. I'm just really worried she will be too cold and get sick and don't understand why she's doing it?
