Hi there!
Normally, I try not to overly stress about this sort of thing, but I've been to many sources and nothing is seeming to help with this persisting issue. I'm beginning to worry a lot, and any advice or tips are greatly appreciated!

Problem: My male Lesser BP (pictured in my profile pic) hasn't taken food since around January. He's about two and a half years old, and I've had him for only a bit less than that. He's always been a picky eater, but has never gone on a strike this long, though nothing in his immediate surroundings have changed much. He doesn't seem weak or anything like that, but he does sometimes seem intimidated by the mice I offer him, or simply uninterested, despite the fact that they're no bigger than the ones he was taking in January.

Details:
-His thermometer is set to around 92 degrees
-The tank's humidity is kept around 55% - 80%




I'm worried for him, but am looking to avoid feeding live if possible. However, whatever would be best for him is my priority.
Thank you all for reading!
