Gang activity

Bird Wrasse, Bluefin Trevally and Blue goatfish

I happened upon this little gang of fish while I was swimming. At the top is a bluefin trevally, in the center a pair of blue goatfish, and at the bottom a male bird wrasse. Trevallies and goatfish regularly hunt together, often in the company of an eel or octopus. They try to flush out or ambush small fish as their prey. The bird wrasse eats mostly marine invertebrates but will also take small fish .

I often see fish like these hunting, but have yet to see any of them snag a meal, though they clearly are reasonably successful hunters.
