The Branching Green/Purple Splatter Coral, Euphyllia parancora, also known as the Anchor Coral, features hammer or anchor shaped tentacles similar to the Torch Coral's. It has brightly colored green, and purple polyps often with neon yellow or green accents that especially shine under actinic lighting. The Branching Green/Purple Splatter Hammer is most active during the day and generally retreats into its skeleton at night. A photosynthetic energy-obtainer, it will also benefit from trace element supplements. It is best kept in a tank with moderate water flow and lighting and should not be kept near other corals due to its stinging nematocysts. If the Hammer Coral gets attacked by any organism, be sure to attend to it quickly as it can cause an infection for other corals. 


The Hammer Coral, scientifically known as Euphyllia parancora, is a captivating addition to saltwater marine aquariums. Its distinct branching structure and vibrant green and purple splatter coloration make it a sought-after species among reef enthusiasts. This comprehensive guide delves into the essential aspects of keeping Hammer Coral in captivity, covering its habitat, care requirements, compatibility, and why it's an excellent choice for your aquarium.

Habitat and Natural Environment of Hammer Coral

The Hammer Coral, scientifically known as Euphyllia parancora, is native to the Indo-Pacific region and thrives in shallow reef environments with moderate water flow and ample sunlight. It typically inhabits areas with sandy or rocky substrates, anchoring itself securely and extending its sweeping tentacles to capture prey.

Reef Compatibility of Hammer Coral

The Hammer Coral is considered perfect for reef aquariums but should be cautiously placed near other corals, as its extended sweeper tentacles can sting neighboring species.

Size and Lifespan of Hammer Coral

Hammer Coral can grow to impressive sizes in captivity, with branching colonies reaching up to a foot or more in diameter. They can live for many years with proper care, with some specimens surviving for over a decade in well-maintained aquariums.

Diet in Captivity

Hammer Coral is primarily photosynthetic, deriving much of its nutritional requirements from symbiotic algae (zooxanthellae) within its tissues. Additionally, it benefits from supplemental feedings of small meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood to promote growth and vibrant coloration.

Aquaculture and Availability

Aquacultured specimens of Hammer Coral are increasingly available to hobbyists, offering benefits such as reduced impact on wild populations and greater adaptability to captive conditions.

Compatibility with Tank Mates

Hammer Coral can coexist harmoniously with peaceful tank mates such as Clownfish, Royal Gramma, Firefish Goby, Cleaner Shrimp, and Coral Banded Shrimp.

Sexual Dimorphism and Coloration Changes

While Hammer Coral does not exhibit significant sexual dimorphism, juveniles may display different coloration than mature colonies, with colors influenced by lighting, water quality, and feeding regimen.

Tank Requirements for Hammer Coral

Minimum Aquarium Size: A tank with a capacity of at least 30 gallons is recommended for a single Hammer Coral colony to provide stability and space for growth.
Water Conditions: Maintain stable water parameters with a pH of 8.1-8.4, salinity between 1.024-1.026, water temperature of 75-80°F, and moderate water flow to simulate natural reef conditions.
