Thread-fin Butterfly Fish

Thread fin butterfly-fish is a fairly common find on most Indonesian reefs.  Easy to spot by the hair like thread that flies off the rear top of the fish.  I am fairly sure the idea of the thread , like the tails of most fish, has evolved as a way of fooling the predators that are hunting them so that they miss them .
