As small as this boxfish was, it wasn’t about to take any of my crap. Got a little bored on a dive so decided to break some scuba diving rules and corner this boxfish. Boxfish are supposed to puff-up when stressed and lose their buoyancy and float upwards. This guy, or gal, hadn’t read the manual. It darted straight at my mask, several times, almost cornering me. Certainly won’t try irritating a boxfish again while scuba diving.
