This SPS (Pocilloporidae) coral is rated moderate difficulty and requires PAR levels of 200–400 with high flow. It derives most of its nutrition from photosynthesis via its symbiotic zooxanthellae. Best placed in the upper rock area of the tank, it has low aggression.

Lighting needs
Provide PAR levels of 200–400 µmol for optimal health and coloration. Moderate accuracy in lighting is sufficient, but consistency matters more than hitting exact numbers. When first placing the coral, start with lower light intensity and gradually increase over 1–2 weeks to prevent light shock.
Spectrum matters as well: a mix of blue (420–480 nm) and white light produces the best fluorescence and growth. Many hobbyists run heavier blue spectrums to enhance coral fluorescence while maintaining enough PAR for photosynthesis.
Flow requirements
Strong, chaotic or random flow is essential. Avoid direct, laminar flow pointed at the coral as this can damage tissue. Instead, use opposing powerheads or gyre pumps to create turbulent, variable flow patterns. The coral should sway gently but not be blasted. Dead spots cause detritus accumulation and increase disease risk.
Placement
Place this coral in the upper rock area of your aquascape. This coral has low aggression and plays well with neighbors. Standard spacing of 1–2 inches is usually sufficient, though growth patterns should be monitored over time.
Secure the coral to rockwork using reef-safe gel super glue or epoxy. Ensure it is stable and won't topple—falling corals get stressed and damaged. Let the glue cure briefly before returning the frag to the tank.
Feeding
This coral is primarily photosynthetic and derives most of its nutrition from light. Supplemental feeding is not strictly necessary but can boost growth and coloration. Broadcast feeding with phytoplankton, amino acid supplements, or dissolved coral foods benefits the colony. Maintain appropriate nutrient levels (nitrate 2–10 ppm, phosphate 0.02–0.08 ppm) to feed the symbiotic zooxanthellae.
Fragging
Fragging SPS corals is straightforward: use bone cutters or a Dremel with a diamond blade to snip branches. Cut at a natural branching point. Glue the frag to a plug with gel super glue—SPS corals encrust over the glue quickly. Recovery is usually fast (days), and the parent colony seals over the cut site. Frag during good health, never when the colony is stressed.
Common issues
- Tissue recession or bleaching: Usually caused by unstable parameters, excessive light, or chemical aggression from neighboring corals. Investigate recent changes in lighting, dosing, or new coral additions.
- Failure to extend polyps: Check flow strength (too strong?), lighting intensity, and water quality. Recent dipping or transport stress can also cause temporary retraction.
- Pests: Inspect for flatworms, nudibranchs, or other parasites. A prophylactic coral dip (Coral Rx, Bayer) upon introduction prevents most pest issues.
- Slow growth: Ensure adequate feeding, stable alkalinity (8–11 dKH), calcium (400–450 ppm), and magnesium (1300–1400 ppm). SPS corals especially need stable, consistent alkalinity for skeleton building.
Frequently asked questions
Is this coral good for beginners?
This coral is suitable for intermediate reef keepers who have stable water parameters and some experience with coral care. Beginners should start with easier species and work up to this one.
What PAR level does this coral need?
Aim for PAR levels of 200–400 µmol at the coral's position. Use a PAR meter to verify actual light levels in your tank, as fixture specs and manufacturer claims often differ from real-world measurements.
How fast does this coral grow?
Growth rate is fast. Factors that influence growth include lighting intensity, flow, feeding regimen, and stable water chemistry. Consistent alkalinity and calcium are the primary drivers of calcification rate in stony corals.
