Common name: mushroom coral

General information

Fungia concinna, commonly known as Mushroom Coral or Disk Coral, is a solitary polyp coral that is highly appreciated in the reefkeeping hobby for its unique shape and vibrant colors. Unlike colonial corals, each Fungia concinna is a single, free-living polyp that can move around the substrate. Its round, disk-like appearance resembles a mushroom, which is where it gets one of its common names.

Care

Mushroom Coral is relatively easy to care for, making it suitable for both novice and experienced aquarists. It thrives in moderate lighting and water flow conditions. Placement on the sandbed or a lower position in the aquarium is ideal to prevent damage to its delicate tissue. Feeding is not strictly necessary as it contains symbiotic algae called zooxanthellae that provide most of its nutritional needs through photosynthesis. However, occasional feeding with small meaty foods can promote growth and health.

Symbiosis

While Fungia concinna does not have the same type of symbiotic relationships as clownfish and anemones, its relationship with zooxanthellae is crucial. The zooxanthellae live within the coral's tissues and provide it with organic compounds produced through photosynthesis. In return, the coral provides the algae with a protected environment and the compounds necessary for photosynthesis.

Habitat

Mushroom Coral is found in the Indo-Pacific region, typically in shallow reef environments. It prefers sandy bottoms or rubble areas where it can easily move around to adjust its position for optimal light exposure and feeding opportunities.
