WYSIWYG Reverse Multi-Head Hammer Coral

Reverse Multi-Head Hammer Coral – Euphyllia parancora – Unique Colour Shift with Active Polyp Growth

The Reverse Multi-Head Hammer Coral (Euphyllia parancora) is an eye-catching variant of the classic Hammer coral, known for its unusual and dramatic reversal of colour. Instead of green-tipped tentacles, this coral boasts bold violet hammers against glowing green stems, creating a striking focal point in any reef setup.

What sets this specimen apart is its multiple polyp heads, signalling vigorous growth and the potential for future splitting and propagation. This branching LPS coral performs best under actinic or blue LED lighting, which amplifies its fluorescence and enhances the depth of its unique colouration.

The coral prefers moderate placement in tanks with gentle to moderate water flow, allowing the tentacles to sway freely without damage. Due to its semi-aggressive nature, it should be spaced from other corals to prevent stinging via sweeper tentacles.

Lighting Requirements:

• Best under low to moderate lighting (PAR 100–150)

• Fluorescence enhanced under actinic or blue LED lighting

• Gradual acclimatisation is recommended for higher intensity setups

---

Water Flow:

• Requires gentle to moderate, indirect flow

• High flow may inhibit polyp expansion or cause tissue damage

• Place in an area that supports flowing tentacle movement

---

Aquarium Compatibility:

• Suitable for medium to large reef aquariums

• Semi-aggressive – allow at least 5–10 cm spacing from other corals

• Works well in Euphyllia gardens when spaced appropriately

• Thrives in tanks with stable parameters and low nutrient fluctuations

---

Feeding Information:

Primarily photosynthetic, but benefits from supplemental feeding:

• Mysis shrimp

• Brine shrimp

• Reef-safe coral foods

Feed 1–2 times per week to encourage continued growth and colour vibrancy.
