A Thorny Mystery Coral

  • It features a very spiky appearance given the elongated corallites of this species.
  • It is a coral rarely (if ever) seen in the marine aquarium trade.
  • A more-common relative is often appealing to beginners and grows well, but can pack a nasty wallop, easily dispatching neighboring corals in a large radius around it.
  • It is now being maricultured in Indonesia by Bali Aquarium, which may mean this unique coral will be available to you in the coming few years.
  • It is featured in the forthcoming July/August 2021 issue of CORAL Magazine.
