Fish poop is a natural item on a lot of menus of marine animals. Corals, fish, inverts...bacteria etc. eat poop. Cucumbers, damsels, tangs, starfish, some worms, and so one regularly eat poop. Even coral. Gross to us, yes, but quite natural to them.
Tangs are open water swimmers. They will always swim around, but they do rest. Perhaps you awaken the fish when you peep inside the tank and it's swimming around to see what's up.

We, as a people, know so much more about outer space than we do about our own oceans. This lack of knowledge can very well spell the dangers that lay in wait for us.
The oceans surely would swallow us before a rock comes down to smite the planet of it's life.
