Watching mantas clean is something regularly seen by snorkels. Many of the cleaning stations in Asia are quite shallow and because you are floating just above them they won't even notice you are there, so you can be sure the behavior will continue uninterrupted. A cleaning station is basically just a large coral head where you're likely to find mantas congregating around. Living within that unique mound of coral will be hundreds of smaller fish like cleaner wrasses and butterfly fish who swim out to meet the mantas and pick off the parasites. Because mantas have to continuously keep moving or else they will sink they will make slow circles around the cleaning station. Other mantas will join in as well and each take their turn getting a little scrub down from the hungry little fish.You'll notice over that that mantas will actually have preferences for cleaning stations, the same way people have preferences over their favorite spas!
