Chalice corals are a group of stony corals belonging to the family Pectiniidae. They are popular among reef aquarists due to their vivid coloration, diverse morphs, and growth patterns. Here is a guide to caring for Chalice corals in your aquarium:
1. Placement: Chalice corals are not strong swimmers, and they prefer to be placed on flat surfaces. Many varieties grow outward horizontally, so they need space around them to avoid contact with other corals. Ensure that they have enough room to grow without bumping into other corals, which can lead to coral wars and injuries.
2. Lighting: Chalice corals have medium to low lighting needs. They generally don't require as much light as some other types of corals like Acropora. They can adapt to a wide range of lighting conditions, but drastic changes can cause stress. It's recommended to start with low to medium light and gradually increase if needed. Sudden high-intensity light can cause bleaching.
3. Water Flow: Chalice corals prefer low to medium water flow. Too strong a flow can cause stress and prevent the coral from fully expanding its tissue. However, adequate flow is necessary to bring them food and nutrients and to keep their surface clean from debris.
4. Water Quality: Like most corals, Chalice corals need clean, stable water parameters. Ensure to maintain proper levels of calcium (400-450ppm), alkalinity (8-11 dKH), and magnesium (1250-1350ppm). They also prefer a pH of around 8.1 to 8.4 and specific gravity between 1.023 and 1.025.
5. Feeding: While Chalice corals get a significant portion of their nutrients from the zooxanthellae algae living in their tissues, they can also benefit from occasional supplemental feeding. Feed them small pieces of marine-based meaty foods like mysis shrimp, brine shrimp, or specially formulated coral foods.
6. Compatibility: Chalice corals are relatively peaceful but can be aggressive if other corals encroach on their space. They can extend sweeper tentacles that sting other corals, so it's essential to provide them with adequate space.
7. Diseases and pests: Chalice corals can be susceptible to diseases and pests like brown jelly disease, rapid tissue necrosis, and pests such as flatworms. Monitor your coral closely for signs of disease or pests. If you spot something wrong, it's important to act quickly and seek advice from an experienced aquarist or a marine biologist.
Remember, each coral is unique, and its requirements can vary depending on its species and individual needs. Always research and observe your particular coral to provide the best possible care. Also, introducing any new coral to your aquarium should be done with caution to avoid introducing diseases or pests to the existing ecosystem.
