Species: Zoanthus spp.
Coral Type: Soft Coral / Colonial Polyp
Emerald Nightmare Zoanthids are a dark, intensely colored designer zoanthid known for their eerie contrast and glowing green dominance. Each polyp typically features a deep emerald to neon green center that appears to “burn” against darker rings of black, deep purple, or forest green, with subtle contrasting skirts that heighten the dramatic effect. The overall look is moody yet highly fluorescent, giving the colony a haunting, high-impact appearance in reef aquariums. As they spread across rockwork, they form dense mats of glowing green polyps that create a strong visual focal point. Under actinic or blue-spectrum lighting, their emerald fluorescence becomes especially intense, producing a vivid, glowing “nightmare” effect.
Coral Type: Soft Coral / Zoanthid
Lighting: Moderate lighting requirements (approximately 75–150 PAR)
Flow Rate: Low to Moderate; gentle, indirect water movement supports healthy polyp extension and helps prevent debris buildup
Food Requirements: Primarily photosynthetic through symbiotic zooxanthellae; occasional feedings of fine particulate coral foods such as Reef Roids or Benereef may enhance growth and coloration
Aggression: Peaceful to Semi-Aggressive; generally reef-safe, though colonies can spread quickly and may overgrow nearby corals if not managed
Placement: Best placed on isolated rock islands or stable reef structures where colonies can expand freely under consistent lighting and flow conditions
We maintain a rigorous, veterinarian-approved quarantine program that includes proactive treatments, careful observation, and daily monitoring to ensure the highest standards of coral and invertebrate health. Our biosecurity practices reduce the risk of any cross-contamination between systems, meaning all our livestock are ready for your display tanks.
