Trachyphyllia geoffroyi is a hard coral . It lives in the coral reefs of the Red Sea , the Indian Ocean and the western Pacific , from southern Japan to Australia , the Solomon Islands and New Caledonia . It occurs mainly in inner reef areas, deep lagoons and on the soft floors around continental islands.
features
The coral has elongated, meandering coralites , which are separated from one another by ditches (flabello-meandroid growth habit). There are only a few, large and fleshy polyps , which are often bright red or green in color, but mostly light green, pink or gray. Some polyps are iridescent or fluorescent . The coral skeleton reaches a maximum diameter of eight centimeters, with fully expanded polyps a colony can reach a diameter of twenty centimeters and more.
Way of life
As a young coral, Trachyphyllia geoffroyi lives firmly attached to stones, shells or snail shells. Later it breaks off under its own weight and then lies loosely with its conical underside on the mostly sandy subsoil.
Trachyphyllia geoffroyi lives in a symbiosis with zooxanthellae , small, unicellular algae from the group of dinoflagellates , which are also important for the nutrition of corals. At night, the coral stretches out its many tentacles, one to two centimeters long, and catches zooplankton .
Trachyphyllia geoffroyi is mainly imported from Singapore and Indonesia for the purpose of keeping aquariums .
