Description
Ultra Teal Glow Wall Hammer Coral (Euphyllia ancora) WYSIWYG XXL is a hammer coral with broad, hammer-shaped polyp tips and flowing tissue. Its movement and coloration are best displayed when the coral is given stable reef conditions, suitable light, and gentle indirect water movement.
Hammer Coral Care
Hammer corals respond best to stable reef conditions. Place this coral where its fleshy polyps can sway without being folded over or driven against the skeleton by a direct stream. Acclimate it gradually to your lighting and leave open space around the colony for nighttime sweeper tentacles.
| Lighting | PAR 100–200 |
|---|---|
| Flow | Low to moderate, gentle indirect flow preferred |
| Placement | Lower to mid-tank with ample open space for sweeper tentacles |
| Feeding | Primarily photosynthetic; optional small portions of appropriately sized meaty foods 1–2 times weekly |
| 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 |
Placement and Acclimation
Wall-forming hammer corals have continuous living tissue along the colony and should be handled carefully to avoid damaging the fleshy margin. Start at the lower end of the stated light range, then adjust gradually while watching polyp extension and tissue condition. Keep the coral separated from neighbors that could be reached by its sweepers.
Maintain consistent salinity and alkalinity, and avoid sudden changes in light or flow. Do not force food into retracted polyps; stable conditions and appropriate placement matter more than heavy feeding.
