The Green Hulk Rhodactis mushroom coral is very easy to care for. It has Neon Green polyps with a rich texture Purple background. It looks simply awesome under actinic lighting. Often referred to as the Tonga Mushroom, Metallic Mushroom, Green Hairy Mushrooms and also sometimes the Tiny Elephant Ear Mushroom, this splendid coral is simple to care for and a fantastic exotic feel to any sort of reef tank.
Water Flow and Lighting
Green Hulk Rhodactis Mushroom corals are all easy to maintain in the reef aquarium. They prefer a low to moderate water movement, and a lower lighting level. Lighting can be Power compacts, T5's, LED's or even Metal Halides. All lighting can grow Mushroom Corals as long as the proper level of light is provided. If a Par meter is available the appropriate lighting level is anywhere from a Par 80 all the way to a Par 150. Which is a wide range of acceptability. For lighting spectrum use between a 14-20K color spectrum for your bulbs for best coloration.
All mushrooms are semi-aggressive and require adequate space between themselves and other corals. Placement can be any where in the aquarium as long as it receives adequate water flow and lighting levels and leaves enough room around your corals that they have room for growth without infringing on another corals growing room or lighting.
Diet and Feeding
Mushroom corals receive the majority of their nutritional requirements through the process of photosynthesis, which simply means their lighting creates symbiotic algae called zooxanthellae in the body of the coral which provides its nutrition. We do recommend providing supplemental food such as micro-plankton or foods designed for filter-feeding invertebrates.
