Green Octospawn Coral

Fimbriaphyllia yaeyamaensis — formerly Euphyllia yaeyamaensis

The Green Octospawn Coral (Fimbriaphyllia yaeyamaensis) is a standout large-polyp stony coral prized for its thick, branching tentacles and bright neon-green tips set against a rich purple to lavender base. Under blue and hybrid reef lighting, this coral displays intense fluorescence and constant, flowing movement that makes it a true centerpiece coral.

Previously classified under the Euphyllia genus, Fimbriaphyllia yaeyamaensis is closely related to frogspawn and hammer corals but is easily distinguished by its unique multi-lobed “octo” tentacle structure. Its fleshy polyps extend generously, giving the colony a full, high-impact appearance.

This species is considered moderately hardy and does well in established reef aquariums with stable parameters. When properly placed, it shows excellent extension and steady growth.

Care Guidelines

• Lighting: Moderate
• Flow: Low to moderate, indirect
• Placement: Mid to lower areas of the aquarium
• Temperament: Semi-aggressive — provide adequate spacing from neighboring corals
• Feeding: Optional but beneficial; accepts fine meaty foods and coral blends

An excellent choice for reef keepers seeking bold color, movement, and a distinctive take on classic Euphyllia-type corals.
