Introduction to Chalice Corals Chalice corals are a striking group of LPS (Large Polyp Stony) corals prized for their vivid colors and intricate patterns. Species such as Echinophyllia and Oxypora are known for their encrusting or plating growth forms, which add a unique texture to reef aquariums. Their vibrant shades of pink, orange, green, and purple, often highlighted with contrasting “eyes” and ridges, make them a favorite among collectors. While Chalice corals require consistent care and stable conditions, their stunning appearance and versatility in placement make them a rewarding choice for reef keepers ready to meet their needs. Location Chalice corals are native to the Indo-Pacific region, including reef systems in Australia, Indonesia, and Fiji. They are commonly found on reef slopes and ledges where water movement is moderate, and light is diffused. These areas provide a sheltered environment, allowing Chalice corals to thrive and develop their vibrant colors. In their natural habitat, Chalice corals contribute to the complexity of the reef structure, creating spaces for various marine life to flourish. Their encrusting and plating growth forms help stabilize reef surfaces and add diversity to the ecosystem. Water Chemistry Chalice corals require stable and consistent water parameters to thrive. Maintaining the following conditions will support their health and vibrant coloration: Calcium: 400-450 ppm Alkalinity: 8-9.5 dKH Magnesium: 1250-1350 ppm Nitrates: 5-15 ppm Phosphates:
