Here is a fish, in this case a Grasby, lying motionless on the bottom… because he is at a cleaning station.

If you look closely, inside his mouth… you will see the shrimp that is at work removing bacteria and parasites.

I am always fascinated that what can be a meal is sometimes not… because of the work they are doing.

And even more fascinated by… How does that get communicated?
