“Platygyra” is a large polyp stony (LPS) coral that is more commonly known as “maze” or “closed brain” coral.

This corals appearance can be described by the genus name in Greek words; “Platy” meaning flat and “Gyros” meaning wide circle.

Platygyra colonies are normally massive and either flat or dome-shaped. The skeleton walls are shared between multiple polyps which twist and turn throughout the coral forming maze-like valleys. These valleys can be irregular in length and shape, even within the same colony.

Platygyra can be seen in shades of grey, green, purple and brown with contrasting valleys. In the wild, Platygyra is found growing in shallow reef environments.

Platygyra is also identified as a semi-aggressive coral species extending sweeper tentacles at night.

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.”
