At depths of 3 and 5 meters the corals of the Acroporidae family are dominated. The highest diversity index is found at a depth of 7 meters with a value of 2.20. The highest uniformity index was found at a depth of 5 meters with a value of 0.69. Family Acroporidae at a depth of 3 and 5 meters found 4 genera namely Acropora, Montipora, Astreopora and Anacropora, while at a depth of 7 meters there were only 2 genera namely Acropora and Montipora.
