Lighting
50-150 PAR is a starting range; fleshy tissue should expand without paling, stretching, or pulling against skeleton.
Echinophyllia spp. / Oxypora spp.
Identify Chalice Coral by thin encrusting or plating body and bright eyes or mouths; then set low placement, moderate flow, and enough separation from Montipora Capricornis and Favia.
Compare thin encrusting or plating body, care range, and nearby lookalikes while checking an ID.

Ranges
These ranges are approximate starting points from the coral database and should be adjusted to the stability and history of your system.
Care
50-150 PAR is a starting range; fleshy tissue should expand without paling, stretching, or pulling against skeleton.
moderate indirect flow should move tissue gently without folding it into sharp skeleton or neighbors.
For Chalice Coral, verify salinity and alkalinity trends before changing placement; repeated moves and direct corrective swings can irritate fleshy tissue.
Chalice Coral requirements vary by specimen, aquaculture history, shipping stress, and tank maturity; use these ranges as starting points, not guarantees.
Feeding
ID
Chalice coral is fleshy with visible eyes, unlike thin SPS Montipora plates with tiny polyps. Separate Chalice Coral from Montipora Capricornis and Favia by checking thin encrusting or plating body, bright eyes or mouths, and sweeper tentacles at night in normal white light. Then confirm corallite walls, polyp shape, tissue inflation, and where recession begins; avoid using a trade name as the only ID evidence. Because trade photos can exaggerate color, skeleton shape, polyp layout, and expansion pattern are stronger clues than color alone.
Placement
Compatibility depends on specimen size, flow, growth, aggression, and spacing. Use these references conservatively and watch for contact over time.
Spacing recommendation: keep about 6 inches of clearance, then adjust based on extension and neighboring coral response.
Troubleshooting
Use these as troubleshooting checks, not a diagnosis. Symptoms may point to more than one issue.

FAQs
Chalice Coral is better treated as intermediate because placement, flow, feeding response, or aggression can vary by specimen.
Start Chalice Coral low in the tank or on the sand/low rockwork when its tissue form allows it. Use 50-150 PAR and moderate flow as a starting point, then adjust from tissue extension, color, and nearby coral response.
Chalice Coral may benefit from careful target feeding with small meaty foods, LPS pellets, and mysis. Use the listed frequency as a starting point: weekly when feeder tentacles are extended. Feed only when the coral accepts food and avoid forcing food into stressed tissue.
Give Chalice Coral about 6 inches of clearance as a starting point. Its database aggression level is High. Use caution near Blastomussa, Candy Cane Coral, and Brain Coral. Avoid close placement with Zoanthids, Mushroom Coral, and Acropora. Compatibility is not a guarantee, so check contact points as colonies expand.
Use this as a troubleshooting check. For Chalice Coral, nearby corals retract while the chalice edge looks intact or slightly pale and Chalice Coral shows less normal extension, inflation, or feeding response than its recent baseline can indicate Chalice Coral nighttime sweeper damage from the growth edge. Likely causes to check include too little spacing, flow carrying sweepers into neighbors, or hidden nighttime contact and recent placement, lighting, flow, or chemistry changes affecting Chalice Coral. Start with these database checks: check Chalice Coral alkalinity trend and look for nearby stinging contact and reduce direct flow if tissue is pressed against skeleton.
For Chalice Coral, verify salinity and alkalinity trends before changing placement; repeated moves and direct corrective swings can irritate fleshy tissue. The database lists 4 months as the minimum tank age and 20 gallons as the minimum tank size. For LPS-style care, protect fleshy tissue from repeated moves, direct flow, and abrupt chemistry corrections.
