Green Duncan 2 Head

Green Duncan 2 Head is a colorful lps coral selected for saltwater reef aquariums. Allow new corals time to acclimate after shipping and avoid sudden changes in lighting, flow, salinity, or alkalinity.

Care Guide

• Care Level: Easy
• Lighting: 75–150 PAR
• Flow: Low to moderate
• Placement: Lower to middle reef
• Salinity: 1.024–1.026 specific gravity
• Temperature: 76–79°F

Placement & Acclimation

Start the coral in a slightly lower-light area than its final target and increase light exposure gradually. Watch polyp extension, tissue inflation, and coloration when adjusting placement. Duncans are hardy and often respond well to occasional small meaty feedings.

Water Chemistry

Stable parameters are more important than chasing exact numbers. A practical reef range is alkalinity around 7.5–9.0 dKH, calcium 400–450 ppm, and magnesium 1250–1400 ppm with measurable nitrate and phosphate. Avoid rapid swings.

Feeding

Most photosynthetic corals receive much of their energy from light, but appropriate coral foods and naturally available plankton can support growth. If target feeding, use small portions and avoid overfeeding the aquarium.

AquaGemCorals Tip

Give new corals time to settle before making repeated adjustments. Stable water chemistry, appropriate light, and suitable flow usually produce better long-term results than constantly moving the coral.
