Aqua Green Hammer Coral Frag
The Aqua Green Hammer is a striking Euphyllia coral known for its crisp aqua-green colouration and classic hammer-shaped tentacle tips. With bright, clean tones and constant, flowing movement, this coral brings a fresh, modern look to reef aquariums while remaining easy to care for.
Its balanced colour and dependable growth make the Aqua Green Hammer an excellent choice for both mixed reefs and LPS-focused systems.
Natural Habitat & Distribution
Hammer corals (Euphyllia ancora / Euphyllia paraancora) are found throughout the Indo-Pacific, including:
-
Indonesia
-
Australia (Great Barrier Reef)
-
Fiji and Tonga
-
The Philippines
They naturally inhabit sheltered reef slopes and lagoon environments, where lighting is moderate and water movement is gentle to moderate.
A Brief History
Hammer corals have long been favourites in the reef hobby for their movement, hardiness, and distinctive appearance. Aqua green colour morphs gained popularity as modern LED lighting highlighted their clean tones and strong fluorescence.
The Aqua Green Hammer remains a timeless Euphyllia variety that suits a wide range of reef styles.
