my BP is about 18 inches right now i'd say, give or take an inch or so. Anyway, when I bought him they were feeding him mouse pinkies, I knew that was too small. Knowing the pinkies were too small, I bought mouse fuzzies. I didn't like that either, fed him twice on them but again knew they were too small. Just this past thursday I fed him a hopper, and I am satisfied with that, but is that the right size or maybe should I go to a small mouse rather than the hopper? Any advice?
