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: <0.10 ppm
• Temperature: 75-80°F

Chalice corals are sensitive to sudden changes in water chemistry, so stability is key. Regular testing and dosing will help maintain the ideal conditions for their growth. Proper salinity (1.024-1.026) and pH levels (8.1-8.4) are essential for skeletal development and overall health.

Lighting

Chalice corals thrive under low to moderate lighting, typically within a PAR range of 50-150. Providing gentle, indirect light helps maintain their vibrant coloration and prevents bleaching or stress. Overly intense lighting can cause tissue damage or color fading, so placement in shaded or lower-light areas of the tank is often ideal.

At Top Shelf Aquatics, we use a combination of Ecotech Marine Radions and metal halides to create balanced lighting that highlights the vivid patterns and hues of Chalice corals. Gradual acclimation to new lighting environments is essential to avoid shocking the coral and to ensure a smooth transition.

Water Flow

Chalice corals prefer gentle to moderate, indirect water flow, mimicking the calmer conditions of reef slopes where they are commonly found. Proper flow helps remove waste and deliver nutrients without causing damage to their delicate tissue. They thrive in the lower parts of the tank, away from strong, torrential currents, which can lead to tissue recession or stress.

At Top Shelf Aquatics, we use a combination of Ecotech Marine MP’s, Reef Octopus Octo Pulse, and Sicce XStream wave makers to create dynamic, customizable flow patterns. This approach ensures that Chalice corals receive the ideal water movement to support their health and vibrant growth.
