We’ve now discovered this interesting, high-density, patchwork colonization of substrates by Galaxea fascicularis in several different and distant locations. It may be that this is a common occurrence throughout the Coral Triangle.
It’s a beautiful sight; a Torch Coral garden, but it’s under stress. I encountered a mild bleaching event while visiting some island offshore reefs in Tomini Bay, the equatorial gulf which separates the Minahassa (North Sulawesi) and East Peninsulas of the island of Sulawesi in Indonesia. The Togian Islands lie near its center. To the east, the Gulf opens onto the Molucca Sea. It’s one of the most diverse coral zones in the world.
This species of coral is very resilient and can tolerate a wide range of water parameters, making it an ideal choice for beginner SPS aquarists.
