I have a large blue regal, red sea sailfin, naso, and yellow tang. The only consistent dropping behavior I've observed is during feeding time. I call it "the smoke screen", because they seem to do it intentionally to distract the other fish while they get the real food.
Cracks me up to see the other fish go for the poo, then realize what they've done and spit it out. Then I feel a little bad for them....until I realize that they fall for it every single time.
Ahhhhh, the simple pleasures of the marine aquarium hobby...
