The research was conducted from 8 to 16 May, 2013. The data was collected from four zones and each zone was set up into two stations as a point observation, at the depth of 79 meters. The percentage of coral coverring was calculated by line intercept transect method, coral genera was counted and identified using the belt transect method. Coral data was analyzed qualitatively based on ecological index. The results showed that the coral covering was range from 7.25 to 68.93% as categorized from bad to good condition. The number of coral was found approximately of 5.523 colonies that consisted of 45 genera and 16 families. The most abundance of coral was Porites and Montipora with percentage of 19.7% and 16.69%, respectively. Coral diversity index was ranged from 1.61 to 3.07 as indicated of low to high. Uniformity index was ranged from 0.44 to 0.68, which was the community in stressful to labile situation. Dominance index (D) was ranged from 0.06 to 0.32 showing that coral dominance was absence.
