WHY SHOULD I BUY THIS CORAL?
The V.A. Witch’s Poison Hammer Coral is a striking, collector‑grade hammer coral known for its eerie, high‑contrast colouration. Displaying toxic‑looking neon greens, acid yellows, and ghostly teal or purple undertones, this coral appears to glow with a “poisoned” effect under blue lighting. Its thick, fleshy hammer‑shaped tips and slow, hypnotic movement create a dramatic and otherworldly presence, making it a standout feature coral for premium LPS and mixed reef aquariums.
CARE LEVEL
Easy–Moderate
Suitable for established reef systems with stable and consistently maintained water parameters.
WATER REQUIREMENTS & GENERAL CARE
• Temperature: 24–27 °C
• Salinity: 1.024–1.026 (32–35 ppt)
• pH: 8.1–8.4
• Alkalinity: 8–10 dKH
• Calcium: 400–450 ppm
• Magnesium: 1250–1350 ppm
Stable water chemistry is essential for maintaining intense colour contrast, healthy tissue, and consistent polyp inflation.
LIGHTING
• Moderate
• PAR Range: 80–150 PAR
Moderate lighting enhances the coral’s toxic neon tones and fluorescence. Gradual acclimation is recommended to avoid colour stress.
PLACEMENT
• Bottom / Lower rockwork
Place on stable rockwork or the sandbed with the skeleton fully supported. Allow adequate spacing to accommodate expansion and nighttime sweeper tentacles.
FLOW
• Low–Moderate
Provide gentle, indirect flow that allows the hammer polyps to sway naturally without being blasted or forced to retract.
FEEDING
• Photosynthetic: Benefit from feeding
Recommended feeding schedule:
• 1–2 times per week
Accepted foods:
• Finely chopped mysis or brine shrimp
• LPS pellets
• Reef roids or fine powdered coral foods
• Liquid coral foods or amino acids
Supplemental feeding supports thicker tissue, improved growth, and enhanced colour saturation.
COMPATIBILITY & BEHAVIOUR
• Temperament: Semi aggressive
• May extend sweeper tentacles, especially at night
• Requires spacing from neighbouring corals
• Can coexist with other Euphyllia / Fimbriaphyllia species if given adequate space
ADDITIONAL INFORMATION
• Family: Euphylliidae
• Origin: Indo‑Pacific
• Natural Habitat: Lagoonal reefs and sheltered reef slopes
• Typical Depth Range: 5–25 m
