Care
Care Notes
Flow
moderate indirect flow should move tissue gently without folding it into sharp skeleton or neighbors.
Stability
For Scolymia Coral, verify salinity and alkalinity trends before changing placement; repeated moves and direct corrective swings can irritate fleshy tissue.
Variability
Scolymia Coral requirements vary by specimen, aquaculture history, shipping stress, and tank maturity; use these ranges as starting points, not guarantees.

How to tell apart
Separate Scolymia Coral from Trachyphyllia Coral and Cynarina Coral by checking single large fleshy polyp, round body, and bold radial color bands 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
Compatibility depends on specimen size, flow, growth, aggression, and spacing. Use these references conservatively and watch for contact over time.
Usually compatible with spacing

Avoid close placement with
Spacing recommendation: keep about 4 inches of clearance, then adjust based on extension and neighboring coral response.
Troubleshooting
Common Problems
Use these as troubleshooting checks, not a diagnosis. Symptoms may point to more than one issue.
Scolymia Coral mantle deflation or exposed rimOpen for symptoms, likely causes to check, and practical next steps.
Symptoms that may indicate it
- single fleshy polyp stays folded, exposes skeleton, or loses smooth inflation
- Scolymia Coral shows less normal extension, inflation, or feeding response than its recent baseline
- changes are localized rather than a confirmed single-cause condition
Likely causes to check
- sand abrasion, sharp rock contact, light shock, or unstable alkalinity
- recent placement, lighting, flow, or chemistry changes affecting Scolymia Coral
- possible irritation from neighbors, pests, detritus, or handling depending on the coral group
Quick checks
- check Scolymia Coral alkalinity trend and look for nearby stinging contact
- reduce direct flow if tissue is pressed against skeleton
- increase spacing and observe the coral under white light and after lights out
Checklist
Common Mistakes
- keep Scolymia Coral on clean sand or a smooth cradle rather than sharp rock
- placing Scolymia Coral before confirming single large fleshy polyp and its spacing needs
- using Scolymia Coral color or trade name alone instead of comparing it with Trachyphyllia Coral
- changing light, flow, and chemistry together when Scolymia Coral looks irritated
- ignoring fleshy tissue protection from direct flow when keeping Scolymia Coral

FAQs
FAQs
Is Scolymia Coral beginner friendly?
Scolymia Coral is better treated as intermediate because placement, flow, feeding response, or aggression can vary by specimen.
Where should Scolymia Coral be placed?
Start Scolymia Coral low in the tank or on the sand/low rockwork when its tissue form allows it. Use 60-160 PAR and moderate flow as a starting point, then adjust from tissue extension, color, and nearby coral response.
Should I target feed Scolymia Coral?
Scolymia Coral may benefit from careful target feeding with mysis, small meaty foods, and LPS pellets. Use the listed frequency as a starting point: weekly or when feeder tentacles are extended. Feed only when the coral accepts food and avoid forcing food into stressed tissue.
Can Scolymia Coral touch other corals?
Give Scolymia Coral about 4 inches of clearance as a starting point. Its database aggression level is Moderate. Use caution near Favia, Favites, and Chalice Coral. Avoid close placement with Torch Coral and Elegance Coral. Compatibility is not a guarantee, so check contact points as colonies expand.
What should I check if Scolymia Coral looks stressed?
Use this as a troubleshooting check. For Scolymia Coral, single fleshy polyp stays folded, exposes skeleton, or loses smooth inflation and Scolymia Coral shows less normal extension, inflation, or feeding response than its recent baseline can indicate Scolymia Coral mantle deflation or exposed rim. Likely causes to check include sand abrasion, sharp rock contact, light shock, or unstable alkalinity and recent placement, lighting, flow, or chemistry changes affecting Scolymia Coral. Start with these database checks: check Scolymia Coral alkalinity trend and look for nearby stinging contact and reduce direct flow if tissue is pressed against skeleton.
What stability issue matters most for Scolymia Coral?
For Scolymia 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.
