Common name: mushroom coral

General information

Fungia horrida, commonly known as Horrid Mushroom Coral, is a solitary polyp coral that is part of the Fungiidae family. Unlike colonial corals, each Fungia horrida is a single, large polyp that is capable of free movement. Its common name 'horrid' is derived from the coral's rough, spiky appearance, which is due to the numerous sharp spines on its skeletal surface.

Care

Horrid Mushroom Coral is relatively hardy and can be a good choice for both novice and experienced reefkeepers. It requires moderate to high lighting and moderate water flow to thrive. Placement on the sandbed or on a piece of rock where it can receive ample light without being damaged by excessive flow is ideal. It's important to ensure that the sharp edges of the coral do not damage other nearby corals or the hobbyist during maintenance.

Symbiosis

While not known for hosting fish or invertebrates, Fungia horrida does have a symbiotic relationship with zooxanthellae, photosynthetic algae that live within its tissues. This relationship allows the coral to receive nutrients from the algae's photosynthesis, which is particularly important for its growth and coloration.

Habitat

Fungia horrida is found in the Indo-Pacific region, typically in shallow reef environments. It prefers areas with sandy bottoms where it can easily reposition itself to optimize light exposure and feeding opportunities.
