This study was carried out to determine the extent of herbivores reef fish composition that can control the distribution of algae. A total of three 50 m transect lines placed at three different locations based on domination of algae functional groups. The study was conducted in Barranglompo Island, Makassar, South Sulawesi, Indonesia in March–June, 2012. The abundance and biomass of fish herbivore was observed through underwater visual census. All species were recorded to number and class size and grouped into their functional groups. The benthic algae cover was measured using the quadrant method in transect lines. Their distributions were observed periodically to determine the extent of the effects of grazing reef fish herbivore on benthic algae. The results showed that the epilithic algal matrix tend to correlate negatively with fish herbivore scrapers while the composition of herbivore reef fish can control the existence of algae distribution within the coral reef resilience. However, the turf algae were negatively correlated with the fish herbivore grazers. This study revealed that the composition of herbivore reef fish can control the existence of algae distribution in coral reef resilience.
