Overview
The Gilded Tempest Hammer Coral is a visual paradox—luxurious and fierce. With molten gold tentacles capped by cool, smoky grey tips, this Euphyllia ancora variety glows with understated drama. Under reef lighting, the soft grey tips give a metallic sheen while the golden body pulses like fire caught underwater.
Sourced from the dynamic reef zones of the Indo-Pacific, this coral is ideal for aquarists looking to balance motion with richness. Its fleshy, hammer-shaped tentacles create rhythmic movement, while the unique coloration adds contrast without overwhelming the eye—perfect for both minimalist and lush reefscapes.
Care & Feeding
Like all Euphyllia, the Gilded Tempest does best in stable systems with moderate lighting and indirect flow that allows its fleshy polyps to move freely. It is photosynthetic but will respond positively to occasional target feedings—try microplankton, reef roids, or finely chopped meaty foods 1–2 times weekly to boost growth and tentacle extension.
Optimal Parameters

Alkalinity (dKH): 8-11
-
Calcium (Ca): 420-460 ppm

Placement
Place the Gilded Tempest Hammer in the bottom to mid-level of your tank where it receives indirect flow and moderate lighting. Avoid high flow, which can damage the soft tissue, and give it plenty of space to account for aggressive sweeper tentacles. This coral can grow quite full and luscious over time—plan for expansion when placing it near other LPS.
