The Green Doughnut Coral is a large polyp stony coral, which is also commonly referred as Cat?s eye, tooth, doughnut, teary eye, or meat coral. It can be one of the largest corals found in the wild, and resembles an artichoke in appearance. The Green Doughnut Coral is non-aggressive in nature, but like most corals, requires adequate space in the tank to expand themselves properly. It features sweeper tentacles that help the Green Doughnut Coral in feeding. It has a perfect amalgamation of hardiness and ease of placement, which makes it an excellent choice for a beginner aquarist. Medium light and low water movement allows for very diverse placement of the Green Doughnut Coral. It may benefit from the addition of calcium, strontium and other trace elements to the water. Supplemental feeding of brine shrimp or micro-plankton is also very important for the Green Doughnut Coral to thrive well in the tank. Its beautiful color adds a splash of vivid green color in the aquarium.
