This guy, a grouper:

sometimes eats lionfish! What a beast.

The grouper is found in the western Atlantic region, and has gobbled up some lionfish every now and then. This is cool because the lionfish now has a natural predator in its unnatural coral environment, meaning a natural way to reduce lionfish population.

Although this is good news, it isn't much news. Groupers are not very abundant, thanks to some overly ambitious fishermen (well not exactly that, but similarly).

Oh well, at least there is sometimes another fish to stand up to the lionfish bully.
