Epinephelus tauvina or greasy rockcod, showing its Heniochus dinner.

This small/medium sized guy at roughly 60centemetres, "all of this species under roughly 90centemetres are males" once landed in the boat while fishing, decided to throw up its last meal.
This happens a lot with predatory fish including sharks, once they decide they are in dire need of lightening the load for escape, “a bit late”, it was already in the boat.
This species of cod or grouper, what ever you want to call it, is very common in SEQ and most of the east coast of Aus as well and for an eating fish, there are not that many that are better eating!
This one gave three of us a nice bit of fillet for dinner.
