Long Tentacle Fungia Corals, Heliofungia actiniformis., also known as Plate Coral, Disc Coral, or Mushroom Coral, are flattened single-polyp corals with a central mouth and a disc-shaped body. Fungia Coral color variations include reds, yellows, greens, oranges, and pinks and often lined with a bright color. Usual sizes range between 2 and 6 inches in disc diameter. Juvenile corals are often pre-attached to substrate or other corals and bear a separation scar as an adult. Fungia Corals have the ability to inflate themselves to almost twice their original size in order to "move" with water currents - keep this in mind during placement. These corals are very easy to care for as they are hardy, require moderate lighting and waterflow, obtain nutrients through photosynthesis (though will take meaty food), and are best housed towards the bottom of the tank. Overall, a great coral for beginner and expert aquarists alike.
