Common names: disc coral, plate coral, tongue coral, fungia, mushroom coral
Natural origin: Indo-Pacific
Sensitivity (Level 1 to 3): Sensitivity depends on genus and species. Species from the genus Fungia are generally tolerant and tend to have excellent success rates among aquarists. Heliofungia
species (often distinguished by their long tentacles) have a reputation
for being much harder to care for and experience relatively poor
success rates in aquaria.
Feeding: These corals have strong
prey capture ability and can feed on meaty marine foods. The size of the
food should easy fit the size of the coral's polyp mouth or mouths.
When in doubt, feed smaller chunks. Slipper corals, Lithophyllon sp. and Polyphyllia sp. often appreciate chopped krill.
Lighting (Level 5 to 8):
These corals can adapt to a range of lighting conditions, but most need
at least moderate lighting for good health and growth. As always,
proper acclimation to new lighting conditions is important.
Water flow: They do well in areas of moderate water flow.
corals should be placed on a flat surface (sand beds are usually best,
but gravel and bare bottoms will do). They can be a bit aggressive, so
please give a little room.
corals can be quite dynamic. They can move independently across flat
surfaces (even up to several inches overnight) and can sometimes even
flip themselves over after falling upside down. Tentacles usually come
out at night, but in captivity they can come out during the day too (or
instead). In healthy tanks, they can show remarkable recovery from
injury or disease. They're also known for occasionally producing babies
called "anthocauli" upon their death.
