🧬 Overview
The Euphyllia ancora “Banana Hammer” is a striking hammer coral known for its bright golden-yellow tentacles and large flowing polyps. The classic hammer-shaped tips create a beautiful waving motion in reef flow, bringing life and movement to the aquarium.
This L-size colony already displays multiple fully developed heads, forming a large fleshy cluster that becomes an immediate centerpiece within reef aquascapes.
The warm banana-yellow coloration stands out strongly among green or purple Euphyllia varieties, creating a vibrant focal point especially under blue-spectrum reef lighting where the fluorescence becomes even more intense.
Large colonies like this are highly desirable as they deliver instant visual impact and mature coral structure.
Selected for:
• Bright banana-yellow coloration
• Large multi-head colony structure
• Thick fleshy hammer tentacles
• Healthy inflated polyps
• Excellent fluorescence under reef LED lighting
🍽️ Care & Feeding
Hammer corals benefit from occasional feeding which promotes stronger growth and polyp expansion.
Recommended feeding 1–2× weekly:
• Mysis shrimp or finely chopped seafood
• Reef roids or LPS coral foods
• Target feeding with gentle flow paused
📈 Optimal Parameters
Parameter | Ideal Range
Alkalinity (dKH) | 7.5–9
Calcium (Ca) | 420–450 ppm
Magnesium (Mg) | 1300–1400 ppm
Nitrate (NO₃) | 5–20 ppm
Phosphate (PO₄) | 0.03–0.10 ppm
📍 Placement
Place in the mid to lower areas of the aquascape where moderate lighting and gentle oscillating flow allow the tentacles to move naturally.
Allow adequate spacing from neighbouring corals, as Euphyllia can extend sweeper tentacles.
