Description
WYSIWYG XL Green Fire Scoly (4″) – Homophyllia australis is a fleshy large-polyp brain coral whose inflated tissue and color are best supported by stable reef conditions, modest light, and gentle indirect water movement.
Care and Placement
Fleshy large-polyp brain corals respond best to stable reef conditions. Give the coral a flat, secure position where the tissue can expand without rubbing against sharp rock or being pressed against the skeleton by direct flow. Acclimate gradually to the stated light range.
| Lighting | Low to Medium — PAR 50–150. Use indirect or diffused light; avoid intense direct lighting that can bleach the polyp. |
|---|---|
| Flow | Low to Moderate — gentle indirect flow; strong direct flow can keep the polyp retracted. |
| Placement | Sandbed or lower rockwork, flat and stable, with room to fully inflate. |
| Aggression | Semi-aggressive — keep neighboring corals out of reach of its feeder tentacles. |
| Feeding | Primarily photosynthetic; offer small portions of appropriately sized meaty food after feeder tentacles extend |
| Care level | Intermediate |
| Water Parameters | Salinity 1.025–1.026 · Temperature 76–78°F · Alkalinity 8–9 dKH · Calcium 420–440 ppm · Magnesium 1300–1400 ppm |
Keeping the Tissue Healthy
Keep detritus from settling in folds and valleys, but avoid a direct powerhead stream. The coral may inflate beyond the visible skeleton, so allow room for daily expansion and nighttime feeding behavior. Handle the skeleton rather than the living tissue whenever possible.
Consistency matters more than chasing a single number. Make lighting and flow changes gradually, keep alkalinity and salinity steady, and watch tissue inflation as the clearest day-to-day placement signal.
