Green Purple Branching Hammer Coral

Euphyllia paraancora, commonly known as the Green Purple Branching Hammer Coral, is a captivating species that thrives in the shallow waters of the Indo-Pacific region. This coral is noted for its striking coloration, featuring vivid green and purple hues that can add a dramatic flair to any marine aquarium. The branching morphology of this coral allows for a dynamic display, as its tentacles sway gently with water movement, creating an enchanting visual effect that is both soothing and lively.

In its natural habitat, the Green Purple Branching Hammer Coral typically resides in lagoons and reef slopes, where it can benefit from ample light and moderate water flow. This species is a symbiotic organism, relying on a mutualistic relationship with zooxanthellae, the photosynthetic algae that inhabit its tissues. This relationship not only provides the coral with essential nutrients but also contributes to its vibrant coloration. In addition, the Hammer Coral is known for its ability to rapidly grow and expand, forming dense colonies that can provide shelter for various marine species.

Behaviorally, the Green Purple Branching Hammer Coral is relatively peaceful, making it compatible with a variety of tank mates. However, it does have a potent sting and should be placed away from more delicate corals to avoid aggression. This species can also extend its tentacles at night, providing a stunning display and potentially attracting small planktonic prey, which it captures for additional nourishment.

Overall, the Green Purple Branching Hammer Coral is not only a beautiful addition to aquariums but also an important species within its ecosystem, contributing to biodiversity and habitat structure in coral reefs.

To thrive in captivity, the Green Purple Branching Hammer Coral requires specific water parameters. Ideally, maintain a temperature range between 24°C to 28°C, with a salinity of 1.023 to 1.025 ppt. A pH level of 8.1 to 8.4 is recommended to ensure optimal health. This coral benefits from moderate to strong lighting, ideally provided by LED or T5 fluorescent fixtures, to enhance its vibrant colors and promote healthy growth.

Feeding the Green Purple Branching Hammer Coral can involve a combination of direct feeding and reliance on photosynthesis. While it can capture small zooplankton and particulate foods, providing a variety of coral foods or finely chopped meaty foods a few times a week can promote growth and vitality.

In terms of compatibility, this species generally coexists well with other corals and marine life, but caution should be taken as it can exhibit aggressive behavior towards neighboring corals with its stinging tentacles. When introducing this coral to a new aquarium, a careful acclimation process is essential to reduce stress. Quarantine new arrivals for at least two weeks to monitor for any signs of disease or pests before introducing them to the main display tank.

The Green Purple Branching Hammer Coral is suitable for shipping due to its hardiness, provided it is packed securely with appropriate moisture and temperature control. It is recommended to ship in insulated containers to maintain stable temperatures during transit. A packing density of 1 coral per 5 liters of water is ideal to prevent stress. Ensure temperatures remain between 22°C and 26°C during shipping. This species is not listed under CITES, simplifying export regulations.
