Placement: On sandbed or soft substrate, away from rock edges
🧬 Overview
The Heliofungia actiniformis “Gold & Negra” is a large, free-living plate coral admired for its elegant tentacle movement and rare metallic coloration.
Our L-size specimens are aquarium-grown, tank-adapted, and selected from long-term in-store colonies to ensure:
-
stable pigmentation and excellent feeding response
-
full, healthy tentacle extension
-
resilience to aquarium conditions
-
natural plate growth pattern with vibrant contrast
Each coral is unique, displaying individual blends of gold, amber, and graphite tones that shift beautifully under varying light spectrums.
🍽️ Care & Feeding
Heliofungias respond well to regular target feeding. Offer:
-
finely chopped mysis or enriched brine shrimp
-
reef pellets or soft coral foods
Feed 1–2× weekly to maintain energy reserves and encourage full inflation.
Avoid placing on sharp rocks; these corals can inflate and move slightly across the substrate.
📈 Optimal Parameters
| Parameter | Ideal Range |
|---|---|
| Alkalinity (dKH) | 7.5–9 |
| Calcium (Ca) | 420–450 ppm |
| Magnesium (Mg) | 1250–1400 ppm |
| Nitrate (NO₃) | 5–15 ppm |
| Phosphate (PO₄) | 0.03–0.10 ppm |
📍 Placement
Place directly on the sandbed or a smooth rock plate in low to moderate, indirect flow.
Avoid direct contact with other corals. Provide room for tentacle movement and to prevent accidental stinging of nearby LPS or soft corals.
