Bass will eat bluegills; it’s what they do. Usually they do it without noticing you noticing them.
A nice largemouth in a tank by himself can be a little self-conscious, you know. Give him a nice fat bluegill to eat and you’ll make him happy.
With a little privacy he might not jump out and slug you. Bass aren’t meant to be cooped up in a tank, but this one’s making the best of it. Just show a little consideration.
It’s bad enough that when he misses he smashes his mug against the glass, but then there are a couple of dudes filming the whole thing. It looks like that bass is starting to get a little flustered.
I know when I order a cheeseburger I expect them to set it down in front of me, not make me chase it around the restaurant until I smash my face. If that was me, I’d tail-slap the closest one and demand another bluegill.
