My checkered male Javier has eaten nothing but one nightcrawler and a fuzzy since mid-November.
I bought him from BHB as an adult which means more than likely he's used to being put down for the winter to breed. He fed aggressively on rat pinks weekly pretty much without cessation since I got him late last June.

He's lost a bit of weight which has me concerned. I know to brumate they need to be in good shape. Interestingly when I offer food he takes interest in it and zips out, even striking at it, but he never holds on or swallows. I bumped his temps a bit and he spends a good deal of time on the hot side. Directly under the bulb in a 4 inch circle the temps are about 93, lowering as you get further away to about 85 as a general temperature, verified with an infrared gun. He has a hide on that side and spends most of the time there so it's not like he's too cold.
