Chalice corals, with their dazzling array of colours and intriguing patterns, are among the most sought-after species in the reef-keeping community. These Large Polyp Stony (LPS) corals are not only a visual treat but also an interesting challenge for aquarists. At Blackfish Marine, we delight in helping you understand and care for these beautiful creatures. This blog will dive into the essentials of Chalice coral care and highlight some of the most popular species to consider for your marine aquarium.
What are Chalice Corals?
Chalice corals encompass several genera, including Echinophyllia, Oxypora, and Mycedium, known for their encrusting growth and broad, flat polyps. These corals are prized for their vibrant colours, which can range from neon greens to deep blues and fiery reds, often highlighted by contrasting veins or luminescent accents. Their unique appearance makes them a standout addition to any reef tank.
Optimal Care for Chalice Corals
1. Lighting: Chalice corals thrive under moderate lighting. LED or T5 lighting that can be dimmed is ideal, as it allows you to adjust intensity based on the coral’s response. Too much light can cause the colours to fade, so it’s important to find the right balance.
2. Water Flow: Moderate water flow is best for Chalice corals. They need enough flow to keep detritus from settling on them but not so strong as to cause damage. Placement in the tank should be such that water movement is indirect to avoid stressing the coral.
3. Water Quality: Like most corals, Chalice corals require stable water conditions. Keep your tank’s temperature between 76-80°F, with a pH of 8.1-8.4. Calcium and alkalinity levels should also be monitored and maintained to support skeletal growth.
4. Placement: Chalice corals should be placed on the lower to mid parts of the tank where they can receive appropriate lighting and flow. They are aggressive corals and can extend sweepers to sting neighbouring corals, so give them plenty of space to grow.
Feeding: Chalice corals benefit from supplemental feeding. They can consume a variety of foods, including mysis shrimp, brine shrimp, and reef-specific foods. Feeding should be done at night when their feeding tentacles are extended.
Species Spotlight
1. Echinophyllia aspera: Often just called “Chalice coral,” this species is known for its smooth, flat surface and vibrant colour patterns. It’s one of the hardier species, making it a good choice for those new to Chalice corals.
2. Oxypora lacera: Known for its deeply ridged skeleton and bright colours, this species adds texture as well as colour to your reef tank.
3. Mycedium elephantotus: Often called the “Green-eyed Chalice Coral,” it features distinctive circular polyps that resemble elephant eyes. It’s particularly striking under actinic lighting.
Conservation and Ethical Considerations
It’s important to source Chalice corals ethically. Over-harvesting can damage natural reefs, so choosing corals from sustainable aquaculture facilities is crucial. At Blackfish Marine, we ensure that all our Chalice corals are sourced responsibly to not only give you the best quality but also to protect natural coral populations.
Conclusion
Chalice corals offer a stunning range of colours and patterns that can make any marine aquarium pop with life. With the right care, these corals can be both a rewarding hobby and a breathtaking display.
