The Goniopora is a beautiful coral to look at, and are one of the most prolific contributors to the world?s coral reefs. The strains of Goniopora have many such beautiful numbers of corals. The Goniopora needs moderate light and intermittent water flow. They are semi aggressive and need to be kept away from neighbor corals in the aquarium. You will often see clown fish around these corals, as they are apt to seek shelter in these corals. The Goniopora has long, elegant polyps that are indisputably stunning and makes the animal a centerpiece in any aquarium.It generally feeds on flowing tiny zoo planktons and thus keeps the aquarium clean and clear. The Goniopora belongs to the group known as Cnidaria in which they have mouth that opens up into one big cavity which acts as a digestive system, where the food is broken down into nutrients and then sent back through the mouth or secreted into the surrounding water. Most Cnidarans has tentacles which can show stinging behavior which can be used as defensive system. The Goniopora does not have excretory system and therefore expels out the waste food into the water. Some corals lack tentacles and instead cover themselves with a thin layer of mucus and use that to collect bacteria and plankton as food.
