Nice! Pineapple morph or albino? Either way so nice. I was trying to share what I have had but having issues downloading..
It looks to be about 3" which means it should be on a feeding schedule of every 2 to 3 days.
When they get bigger like adults it is even less.. I personally always used an under tank heater, like you have attached to the back.
On the back only allows for the heat to go up and the ground temp would be the same as room temp (usually). Plus, the gage is where heat would be moving upward.
People do the back heat pad because if you place under the tank without leaving a gap of about 1" the glass will get hot and cook your frog. Not good!
I would place the thermometer 1/2" under the surface and see what your frogs temp really is. The faster she can digest the faster she will eat more.
Their hibernation isn't the same as many other frogs, they hibernate when dry and warm. Their skin get hard to retain water but this is normal.
Sorry I get specific but not sure what your experience is so always go basic.. Owned my first Giant Pacman in 1978 and had one a few years ago, which means---- Still love them..
After all that-- It is probably temperature.
