On one Bonaire night dive, shortly before covid, my brother and I spent a good part of our dive watching a gang of hunters working the Reed.
One giant Green Morrey was freeswimming, on the hunt, and moving south along the reef, with an entourage of 5 large Tarpon as his wingmen.
The Morrey and the Tarpon made a very effective "gang", with the eel diving deep into the cracks and crevices of the reef hunting, where many fish escaped the eel only to be scarfed up by the big fish.
It was quite a sight to see those 6 working together.
