Common name: Long Tentacle Plate Coral

General information

The Plate Coral, Heliofungia actiniformis, is a large polyp stony (LPS) coral known for its long, flowing tentacles and striking resemblance to a sea anemone. It is a solitary coral, meaning it consists of a single, large polyp attached to a skeletal base. This species is often appreciated for its movement in the water, as its tentacles sway with the currents, adding a dynamic element to the reef aquarium.

Care

Plate Corals require moderate to high lighting and moderate water flow within the aquarium to thrive. They are photosynthetic and host zooxanthellae in their tissues, which provide nutrients through photosynthesis. However, they also benefit from supplemental feedings of meaty foods like mysis shrimp and finely chopped seafood. Care should be taken to ensure that their long tentacles do not come into contact with other corals, as they can sting and damage neighboring species.

Symbiosis

While Heliofungia actiniformis does not have a symbiotic relationship with fish like clownfish and anemones do, it does host zooxanthellae, symbiotic algae that live within its tissues. These algae provide the coral with the majority of its nutritional needs through the process of photosynthesis.

Habitat

Heliofungia actiniformis is found in the Indo-Pacific region, typically in shallow, warm waters on reef slopes or lagoons. They prefer sandy bottoms where they can anchor themselves and extend their tentacles to capture food particles from the water column.
