Information
Chalice Corals are a broad collection of corals that are loosely jumbled together. Several different genera of corals are represented ranging from Echinopora, Oxypora, Mycedium, and even Lithophyllon. As such, care requirements are going to be generalized more than other corals because these are very different corals that all get lumped in together.
Lighting
Moderate lighting is recommended for best coloration and overall health. Metal Halide lighting or a large bank of high output fluorescent can sometimes be tolerated but typically these corals do not fare well under extremely intense light. If not provided proper lighting, the colors may fade. Chalice corals tend to have some of the most impressive fluorescence in the reef keeping hobby which can be best viewed under actinic LED's. In the summer they tend to brown out considerably but will return to more attractive coloration once in a stable home reef aquarium.
Water Flow
Moderate water movement is recommended. Flow that is too low can allow detritus to settle on the colonies which creates dead spots. Flow that is too strong may knock a chalice over because the shape of the colony acts as a sail that can catch the water current.
Feeding
Chalice coral relies heavily on the products of their zooxanthellae, but are surprisingly one of the most aggressive eaters. We have tried feeding it a number of different types of food ranging from frozen foods to pellet foods.
