Then there are others who have seen them destroying a leather, acropora or gorgonian. There are two theories circulating about these differing behaviours. One is that there is more than one species and are very difficult to tell apart; one eats film algaes and the other eats corals. But then there is also the theory that they are opportunistic and feed on corals when their supply of algaes are running out. But don't jump to conclusions that they are consuming your corals when you seen them on there... more than likely they are just cleaning to film off the coral. The odds of finding a coral predator are low.
