A BP should not be eating 3 times a week especially at that size, BP in captivity are overfed, and overfeeding a male will translate in long fast.Here's the issue. Sol, our BP, ate the first day in the the new setup and then once a week ago. We're used to him eating 3 times a week.
If you want a healthy BP you should feed it nothing bigger than a small rat (75 grams max for a large male) once a week and skip a week on occasion.
At this size a 55 grams weekly is more than enough. If you feed multiple prey it should be done in one sitting.
