Coral Care Info Pectinia

Pectinia corals, often referred to as Lettuce corals or Chalice-type LPS, are known for their thin, plating structure and sharp, jagged ridges that give them a unique, aggressive appearance. They come in a variety of bright colors and can develop dramatic shapes as they grow. Pectinia are visually striking but require careful placement due to their strong aggression and delicate tissue.

Care Requirements

Lighting (PAR Range)

• Pectinia corals typically do best in 75-150 PAR.
• Moderate lighting helps maintain coloration without causing stress.
• Too much light can lead to bleaching or tissue damage.
• Always acclimate new specimens slowly, especially those from new arrival corals.

Flow

• Moderate, indirect flow is ideal.
• Flow should keep debris from settling without directly blasting the coral.
• Strong direct flow can damage thin tissue edges.
• Consistent flow helps maintain overall health.

Placement

• Best placed in the lower to middle areas of the tank.
• Can be mounted on rockwork where it can grow outward.
• Requires significant space due to aggressive sweeper tentacles.
• Placement should be planned carefully in tanks with small polyp stonies corals, which can be easily damaged.

Aggression

• Highly aggressive coral.
• Extends long sweeper tentacles, especially at night.
• Can sting and damage nearby corals at a distance.
• Should always be given plenty of space from other corals.

Growth Rate

• Moderate growth rate under stable conditions.
• Grows in plating and branching forms with jagged edges.
• Growth can create dramatic, layered structures.
• Stable water chemistry supports consistent development.

Feeding

Pectinia corals benefit from occasional feeding, although they rely primarily on photosynthesis. Supplemental feeding can improve growth and coloration when done properly. Newly added specimens from newest corals should be given time to adjust before regular feeding begins.

• Feed small meaty foods such as mysis shrimp or coral-specific foods.
• Feeding once or twice per week is typically sufficient.
• Avoid overfeeding to maintain water quality.

Tank Compatibility

Pectinia corals require careful placement in mixed reef aquariums due to their aggressive nature. They are not suitable for crowded tanks where corals are placed close together. In systems that include soft corals or spreading species like zoanthids, it is important to maintain a safe distance to prevent stinging and damage.

• Keep far from other corals due to long sweeper tentacles.
• Avoid placing near delicate or slow-growing species.
• Best used as a standalone or isolated showpiece coral.

Common Problems

• Tissue damage from strong flow or handling.
• Stinging damage to nearby corals if placed too close.
• Bleaching from excessive lighting.
• Detritus buildup if flow is insufficient.

Tips for Success

• Provide moderate lighting and indirect flow.
• Give extra space due to aggressive sweeper tentacles.
• Handle carefully to avoid damaging thin tissue.
• Maintain stable water parameters.
• Place where it can grow outward without interference.

Frequently Asked Questions

Is Pectinia aggressive?
Yes, Pectinia is highly aggressive and can extend long sweeper tentacles that sting nearby corals.

How much space does Pectinia need?
Pectinia should be given plenty of space, as its sweeper tentacles can reach several inches beyond the colony.

Does Pectinia need to be fed?
While it can survive on light alone, occasional feeding can improve growth and overall health.

Is Pectinia difficult to keep?
Pectinia is moderately easy to care for but requires careful placement due to its aggression and delicate tissue.
