Dwarf fuzzy and honeycomb grouper video

I was taking a video of my lionfish when my honeycomb grouper decided to see what the heck was going on.

They are the only two predators in that tank, so I think when the lionfish is looking at something the grouper wants to know want is going on, and especially if there's food involved.
They're kind of an odd couple, the grouper likes to sit on top of the lionfish and he doesn't seem to mind.
