Coral Care Info Scolymia

Scolymia corals, often referred to as “Scolys,” are highly sought-after large polyp stony corals known for their single-polyp structure, intense coloration, and thick, fleshy appearance. They are often used as premium centerpiece corals due to their vibrant patterns and ability to inflate significantly under proper conditions. Scolymia are relatively hardy but require stable water parameters, gentle flow, and proper placement to maintain their health and coloration.

Care Requirements

Lighting (PAR Range)

• Scolymia corals typically do best in 50-120 PAR.
• Moderate to lower lighting helps maintain deep coloration.
• Too much light can cause bleaching or tissue stress.
• Always acclimate new specimens slowly, especially those from new arrival corals.

Flow

• Low to moderate, indirect flow is ideal.
• Flow should gently move water across the coral without direct impact.
• Strong flow can damage fleshy tissue and prevent expansion.
• Gentle flow supports full inflation and feeding response.

Placement

• Best placed directly on the sand bed.
• Avoid placing on sharp rock surfaces that can damage tissue.
• Allow space for full expansion and feeding tentacles.
• Placement should be planned carefully in tanks with small polyp stonies corals, which may be sensitive to contact.

Aggression

• Moderately aggressive coral.
• Can extend feeder tentacles, especially at night.
• May sting nearby corals if placed too close.
• Should be given space in mixed reef environments.

Growth Rate

• Slow growth rate.
• Maintains a single-polyp structure rather than forming colonies.
• Growth is seen more in size expansion than multiplication.
• Stable parameters support long-term health.

Feeding

Scolymia corals respond very well to feeding and often show improved expansion and coloration when fed regularly. While they are photosynthetic, they actively capture food and benefit from supplemental feeding. Newly introduced specimens from newest corals should be allowed time to settle before starting a feeding routine.

• Feed meaty foods such as mysis shrimp, brine shrimp, or chopped seafood.
• Target feeding once or twice per week is typically sufficient.
• Ensure food is fully captured to prevent waste and maintain water quality.

Tank Compatibility

Scolymia are well suited for mixed reef aquariums when given proper spacing and placement. Their fleshy tissue makes them vulnerable to damage from aggressive neighbors. In tanks that include soft corals or spreading colonies like zoanthids, careful placement helps prevent contact and irritation.

• Keep on open sand away from aggressive corals.
• Avoid placing near species that may sting or overgrow them.
• Ensure stable placement to prevent shifting or damage.

Common Problems

• Tissue damage from placement on rock or rough surfaces.
• Bleaching caused by excessive lighting.
• Failure to expand due to strong flow or stress.
• Injury from nearby corals or unstable placement.

Tips for Success

• Always place Scolymia on soft sand.
• Provide gentle flow for full expansion.
• Feed regularly to support health and coloration.
• Maintain stable water parameters.
• Allow enough space to prevent aggression-related damage.

Frequently Asked Questions

Is Scolymia a beginner coral?
Scolymia can be kept by beginners with stable tanks, but they require careful placement and consistent conditions.

Does Scolymia need to be fed?
While they can survive on light, feeding improves growth, expansion, and coloration.

Can Scolymia be placed on rock?
No, they are best placed on sand to prevent damage to their underside.

Is Scolymia aggressive?
They are moderately aggressive and can extend feeding tentacles, so spacing is important.
