I'm going to also suggest that its on the usual hunger strike this time of year but will hopefully get out of it soon. Did you by chance ask the breeder/seller when it last ate and what he/she fed it? It may have been on a hunger strike before you got it. Just a thought. As for prominent spine, I wouldn't worry. It is a bit thin but not dangerously thin. Oh, and lastly, have you tried leaving the F/T in the enclosure? Your BP might eat it when no one is looking. Good luck.
