Orange Cup Coral Tubastraea coccinea dominates the scenery at the entrance of this tunnel. The species occurs in tropical and subtropical Western Atlantic and Indo-Pacific in a depth range from 1-37m. This large-polyp stony coral is not a reef building species. The coral extends beautiful translucent tentacles at night. Tubastraea coccinea does not contain zooxanthellae in its tissues as many tropical corals do, allowing it to grow in complete darkness as long as it can capture enough food. \n\nAt first glance you can hardly see any fish, but there are many of them! \nMany Anthias, a Coral Hind, a Giant Squirrelfish, Soldierfishes, Filefishes, Butterflyfishes and Damselfishes. \n\nFish also like shortcuts, so a tunnel is welcome! \nDramai Rock, Triton Bay, Westpapua, Indonesia \n4°2'33.036 S 134°14'12.858 E at 5m depth
