🧬 Overview
The Golden Venom Hammer is a rare and electrifying morph of Euphyllia ancora, celebrated for its toxic yellow luminescence and fluid motion. Its fleshy anchor-shaped tentacles sway gracefully with the current, catching the eye instantly and becoming a centrepiece in any reef layout.
This variety is particularly prized by collectors and aquascapers seeking bold colour impact without sacrificing natural elegance. Its glow intensifies under blue-spectrum lighting, making it appear almost molten.
🍽️ Care & Feeding
Though primarily photosynthetic, this Euphyllia benefits from occasional feeding. Offer mysis shrimp, enriched brine, or specialised coral pellets once a week to support tissue growth and polyp inflation.
Avoid high, direct flow and sharp rock edges, as its delicate tissue can easily be damaged. Provide sufficient space between other corals to prevent stinging by its sweeper tentacles.
📈 Optimal Parameters
-
Alkalinity (dKH): 8–11
-
Calcium (Ca): 420–460 ppm
-
Magnesium (Mg): 1250–1350 ppm
-
Nitrate (NO₃): 2–10 ppm
-
Phosphate (PO₄): 0.01–0.05 ppm
📍 Placement
Place in mid to lower areas of the reef with moderate, indirect water movement. This morph prefers open, stable surfaces and performs best under hybrid or blue-dominant LED systems that enhance its fluorescent yellow tones. Ensure space for polyp expansion and protection from aggressive neighbours.
