WYSIWYG Screaming Red Chalice

Chalice corals, belonging to the family Pectiniidae, are a highly sought-after group of large polyp stony corals (LPS) known for their striking appearance and vibrant colors. These corals exhibit a variety of growth forms, including encrusting, plating, and cup-shaped structures, which contribute to their unique and eye-catching look. Chalice corals are available in a wide spectrum of colors, including intense blues, purples, pinks, oranges, and greens, often with intricate patterns and contrasting edges.

Native to the Indo-Pacific region, chalice corals inhabit a range of reef environments, from shallow waters to deeper reef slopes. In an aquarium setting, they require moderate to high lighting and moderate water flow to mimic their natural habitat. Stable water parameters are crucial for their health, with an optimal temperature range of 72-78°F, a pH of 8.1-8.4, and a calcium level of 400-450 ppm.

Chalice corals are relatively hardy but can be sensitive to changes in water quality and environmental conditions. They are generally suitable for both beginner and experienced aquarists who can maintain consistent water parameters. Regular monitoring and maintenance of alkalinity, calcium, and magnesium levels, along with diligent water changes and filtration, are important for their well-being.

These corals rely on the symbiotic zooxanthellae algae within their tissues for the majority of their nutritional needs through photosynthesis. They can also benefit from supplemental feedings of small meaty foods, such as brine shrimp or mysis shrimp, and coral-specific foods, which can enhance their coloration and growth.

Chalice corals can exhibit sweeper tentacles, which they use for defense and capturing food. These tentacles can extend several inches from the coral and can sting nearby corals, so it's important to provide adequate space between chalice corals and other corals in the aquarium to prevent aggression.

With proper care, chalice corals can become a stunning centerpiece in a reef aquarium. Their vibrant colors, intricate patterns, and diverse growth forms add a dynamic and visually appealing element to the underwater landscape, making them a favorite among coral enthusiasts
