Red Chalice

Chalice coral is another popular type of LPS (Large Polyp Stony) coral in the reef-keeping community. Known for its striking colors and unique, often wrinkled or undulating surface, chalice corals are visually captivating and can be a showpiece in any reef tank.

### Key Points About Chalice Coral:
– **Appearance**: Chalice corals come in a variety of vibrant colors, including reds, blues, greens, and oranges. They often exhibit multiple colors in a single specimen, with intricate patterns. The coral’s surface can be smooth, bumpy, or highly convoluted, and the polyps are usually small and embedded in the coral tissue.

– **Lighting**: Chalice corals prefer low to moderate lighting. Intense light can cause them to lose color or even bleach, so it’s essential to place them in areas of the tank where they are shielded from direct, strong light.

– **Flow**: They thrive in low to moderate water flow. High flow can cause tissue recession or inhibit the coral’s ability to extend its feeding tentacles.

– **Feeding**: Like Acan corals, chalice corals are photosynthetic but benefit from supplemental feeding. They can be fed small meaty foods such as brine shrimp, mysis shrimp, or specialized coral foods. Feeding typically occurs at night when their feeding tentacles are extended.

– **Placement**: Chalice corals should be placed on the substrate or lower areas of the tank, away from direct light and strong flow. They can be somewhat aggressive, with sweeper tentacles that can sting neighboring corals, so they need sufficient space.

– **Water Parameters**: Chalice corals require stable water conditions, similar to other LPS corals. A specific gravity of 1.023-1.025, a temperature range of 75-80°F (24-27°C), and balanced levels of calcium, alkalinity, and magnesium are ideal.

Chalice corals are often sought after by collectors due to their beautiful coloration and unique shapes. While they are relatively hardy, they do require attention to lighting and flow conditions to thrive. Their dramatic appearance makes them a standout addition to any reef aquarium.
