Euphyllia ancora

Datasheet

General Description

The Hammer Coral, scientifically known as Euphyllia ancora, is a large polyp stony (LPS) coral characterized by its hammer-like, anchor-shaped tentacles. Its polyps, visible both day and night, conceal its skeletal base. This coral can exhibit colors ranging from gold, green, tan to brown, with vibrant lime green, yellow, or pink tips on its tentacles that fluoresce under actinic lighting. Some varieties may have branched structures, resembling the appearance of Torch Coral (E. glabrescens).

Demands and Hardiness

While being moderately challenging to maintain, the Hammer Coral thrives well under proper water conditions in an aquarium setup. It necessitates moderate lighting and water movement within the tank. Care should be taken during nighttime as its sweeper tentacles can extend up to six inches, requiring ample spacing between neighboring corals. To ensure its sustained well-being, regular supplementation of calcium, magnesium, strontium, iodine, and other essential trace elements into the water is vital. Additionally, feeding the Hammer Coral weekly with micro-plankton or brine shrimp contributes to its overall health.

Lighting

Moderate lighting is recommended for the Hammer Coral to support its photosynthetic needs and vibrant coloration. Adequate lighting helps in the growth and sustenance of this coral species within the aquarium environment.

Water Flow

Maintaining a moderate water flow is crucial for the Hammer Coral. Providing moderate water movement aids in the dispersion of nutrients and oxygen, preventing detritus buildup around the coral. This balanced flow ensures the coral's overall health and well-being.

Feeding

Supplementing the Hammer Coral with additional food weekly, such as micro-plankton or brine shrimp, enhances its nutritional intake and supports its growth. Feeding this coral regularly contributes to its vitality and resilience in a captive environment.

Propagation

Hammer Coral can be propagated through fragmentation, where carefully cutting and fragging a healthy portion of the coral can lead to the growth of new colonies. Proper handling and care during the propagation process are essential to ensure successful outcomes.

Localization & Habitat

In the wild, Hammer Corals are commonly found in the Indo-Pacific region, inhabiting shallow reef environments with moderate water flow and ample sunlight exposure. They are often situated on rocky substrates or sandy bottoms, showcasing their distinctive hammer-shaped tentacles in the vibrant marine ecosystem.
