A Dragonfly nymph got into my tank somehow a few months ago, my two Rams both tried to eat it at the same time and played tug of war with it, til it got ripped in half. A little sadistic, but i found it hilarious.
Also the other day I threw in some broken up algae wafers. My BN Pleco started eating one, then one my Amanos swooped in, stole the wafer, and swam away as fast as it could.
