Blastomussa species are a resilient large polyp stony (LPS) coral that have a unique growth form, where each polyp can grow upward and outward until it is no longer considered a colony.

After growing apart it is then possible that the individual clones will compete with each other for space and resources.

They are most commonly found with red or purple rims and a green center, but have also been found to have gold rims in some rare cases.

Each polyp is fleshy and when healthy can expand to hide the base of the skeleton in a ?dome? shape.

In the wild, Blastomussa species are found in turbid waters on the lower reef slopes.

Acclimation Guide

  • It is highly recommended to acclimate all corals to a new environment to prevent shocking corals.
  • Place the corals in the water from the packing bags and slowly add the water from new environment (Dripping method is recommended).
  • Use the water parameter above as a guide.
  • When the vessel becomes full , replace the water with the new environment water by a small amount at a time.
  • Ensure the water temperature matches with the new environment’s water.
  • After the corals have spent adequate time in the acclimation water, gently place the corals to a new environment.
  • It is recommended to place new corals under lower light intensity than usually required. Once corals show no signs of stress, it can be moved to higher lighting area gradually.”
