Long Tentacle Plate Corals are a large polyp stony (LPS) coral often referred to as a Heliofungia Plate, Mushroom, or Disk Coral. With its long tentacles extended, it takes on the appearance of an colorful anemone. It is a solitary, semi aggressive coral, and with its long tentacles can sting other corals that it comes in contact with. With placement in the aquarium, keep in mind that it will often inflate itself with water and expand to twice its size, with sweeper tentacles extending well beyond its base. It will do best on the bottom of a reef aquarium, preferably lying on a fine sandy substrate. The Long Tentacle Plate Coral is easy to maintain in the reef aquarium and makes an excellent candidate for the beginner reef aquarist.
Difficulty A hardy and easy to care for coral making it a good beginner coral.
Aggressiveness This is a semi aggressive species. They can sting nearby corals so leave a few inches between Long Tentacle Plate corals and other corals in the reef aquarium.
It requires moderate water flow.
It requires moderate lighting (PAR 100-150). T5's, Metal Halides, or LED's can all grow Heliofungia plate corals when the proper PAR levels are provided. We recommend a 14-20K color spectrum for best coloration.
For placement keep in mind that it will do best on the bottom of the reef aquarium, preferably lying on a fine sandy substrate. L.T. Plate corals often inflate themselves with water and expand to twice their size so enough room must be left for both the expansion and for its sweeper tentacles which can extend beyond its body.
Diet and Feeding
We recommend feeding both a liquid micro-plankton and brine shrimp.
In captivity, propagation of Heliofungia corals can be done by cutting the disc into multiple pie shaped wedges. Use a water saw or other saw that can quickly saw through the bone. Make sure the animal has been well fed and is healthy before attempting this type of fragmentation.
