GA pretty much hit it on the head...Just to give more proof to this.. My BP has gone several months without eating on more then on occasion and her environment is ideal in all ways.

I honestly would not be worried about 2 weeks at all. If you tank settings are all where they should be it may just be as simple is you BP is starting to go through the shedding cycle. During this time BP's have no interest in eating in my experience.

A upcoming shed can be seen by a dull "cloudy" appearance a couple days before the shed will actually happen, also their underbelly will have a pinkish tint. They will look completely normal again for a day ro so then start the actual shed.

Just keep up your care and keep an eye for any signs that something may be medically wrong with your BP. Again i wouldn't be too worried at all though
