Acropora hard corals sometimes called staghorn coral are sometimes seen on the Sisters Islands. The Acropora goby almost never leaves the safety among the branches of Acropora corals. This colourful fish is unfortunately affected by harvesting for the live aquarium trade, corals often being broken to get at the fish.  More about this fish on the wildfacts sheets on wildsingapore.  For a high res version of this photo, please review the details on about using my photos.
