Overview

Hammer Coral is an attractive large-polyp stony coral that is widely recognized for its hammer- or anchor-shaped tentacles. These corals display a variety of colours, including green, tan, pink, and purple, and are prized for their flowing, waving tentacles that add movement and visual appeal to reef aquariums. This coral originates from the Indo-Pacific region and can adapt well to a variety of tank conditions, making it a popular choice for aquarists with moderate experience.


Behaviour and Placement

Hammer Corals have a semi-aggressive temperament due to their tentacles, which can extend and sting neighbouring corals. To avoid potential territorial issues, place them with adequate space around the colony, ideally at the bottom to the middle of the tank. Moderate lighting and flow allow the tentacles to sway gently without stress, creating an optimal environment.


Feeding

While Hammer Corals rely primarily on photosynthesis, they benefit from occasional feeding with meaty foods like mysis or brine shrimp. Target feeding once or twice weekly can enhance growth and vibrancy.


Care Tips
  • Maintain stable water parameters, as Hammer Corals are sensitive to fluctuations.
  • Provide moderate lighting and gentle water flow for best results.
  • Allow sufficient space between Hammer Coral and other corals to prevent stinging.


Compatibility

Hammer Corals are generally compatible with other peaceful or semi-aggressive coral species. However, they should not be housed too closely with other aggressive corals to prevent potential conflicts. They are reef-safe and make a wonderful addition to mixed reef tanks, where their movement and striking appearance can be fully appreciated.


Final Thoughts

Hammer Corals are a beautiful and dynamic addition to marine aquariums, offering a unique texture and motion. With moderate care needs and a forgiving nature, they are an excellent choice for aquarists looking to add character and colour to their reef tanks.
