WYSIWYG Double-Head Toxic Green Hammer Coral – Euphyllia ancora

Double-Head Toxic Green Hammer Overview:

The Double-Head Toxic Green Hammer Coral (Euphyllia ancora) is a striking LPS (Large Polyp Stony) coral, celebrated for its vivid green coloration and unique hammer-shaped tentacles. With two prominent heads, this coral offers enhanced visual appeal and dynamic movement, making it an excellent centrepiece for reef aquariums.

Lighting Needs:

This coral flourishes under moderate lighting conditions, with a PAR range of 80–150. Suitable lighting options include LED, T5, or hybrid systems. Gradual acclimation to lighting changes is recommended to prevent stress or bleaching.

Water Flow Requirements:

Moderate, indirect water flow is ideal. This ensures the coral’s tentacles sway gently, mimicking natural reef conditions. Avoid direct, high-intensity currents, which can cause tissue damage or retraction.

Aquarium Compatibility:

While the Hammer Coral is semi-aggressive due to its sweeper tentacles, it can coexist with other Euphyllia species like Torch or Frogspawn corals when adequate space is provided. Ensure a minimum distance of 6 inches from other corals to prevent stinging incidents.

Feeding & Nutrition:

Primarily photosynthetic, this coral benefits from supplemental feeding 1–2 times per week. Suitable foods include mysis shrimp, brine shrimp, and specialised coral foods. Target feeding during polyp extension periods enhances growth and vitality.
