The Green Center Button Polyps are the coolest thing to keep in an aquarium. They make a great choice for any tank as it imparts a beautiful splash of color in your tank under actinic lighting. The Green Center Button Polyps are hardy and make a good choice for any beginner aquarists. They thrive really well in a tank showing optimal water quality and temperature conditions. The Green Center Button Polyps are very easy to propagate and therefore it is not necessary to buy a larger frag, since a polyp or two soon turns in to eight and on and on. They require moderate to high alkalinity, calcium and salinity levels for its proper growth and development. The Green Center Button Polyps grow like a colonial mat like structure which later covers up a whole rock. Often some species of zoanthids are poisonous in nature, such as palythoas, and therefore handling the Green Center Button Polyps require precautions. You should properly wash your hands after you are finished working with them. Most of them host the symbiotic Zooxanthellae in their tissue, which creates food and provides nutrition to it. The Zoanthids will thrive in all types of marine lighting, because of this the Green Center Button Polyps makes a very good addition to any first time reefers tank. Also, most of the Zoanthids shows stinging behavior. Due to the photosynthesis process, the Green Center Button Polyps do not need any additional supplements.
Green centers with brown skirts.Zooanthids are extremely hardy and an excellent beginner coral. They can spread rapidly so care must be taken to ensure they donít choke out other corals.Zooanthids are photosynthetic and donít need special feeding.Zooanthids prefer low to moderate water motion.Does well within a range of at least 76ļ to 84ļ F.Will tolerate very low light levels, but do better with stronger lighting.Often referred to as "Zoos" Button Polyps are very easy to care for and great for everyone from beginner to expert. They grow and spread very quickly and can be easily propagated.Corals are part of a biological group known as Cnidaria. Most Cnidaria have a mouth,or mouths, that opens into one big body cavity. Due to the lack of a true digestive system, this cavity acts in its place and after the food is broken down the nutrients are then sent through the rest of the body as food. There is also no excretory system; therefore the waste is sent back through the mouth or secreted into the surrounding water.Tentacles of varying size will usually surround the mouth of Cnidaria. Most Cnidaria have tentacles with stinging cells that can shoot tiny poison darts into their prey or can even be used as a defense mechanism. Some corals lack tentacles and instead cover themselves with a thin layer of mucus and use that to collect bacteria and plankton as food. Some corals even use both of these methods. Cnidaria can either bean individual animal or members of a complex colony. These "Colony Corals" share the food and nutrients taken in by each individual.Corals have tiny living organisms that actually live in their tissue. These are called zooxanthellae and they are the reason why such strong lighting is needed in the saltwater aquarium. These algae-like creatures provide the coral with oxygen and other nutrients that are produced during photosynthesis. During this process, the zooxanthellae take up carbon dioxide and provide nutrients to the coral.
