Long Tentacle Plate Coral (Heliofungia actiniformis)

3"+ Diameter 

Add incredible movement and a unique centerpiece to your reef with the Long Tentacle Plate Coral (Heliofungia actiniformis). Known for its exceptionally long, flowing tentacles and vibrant coloration, this free-living LPS coral creates an anemone-like appearance while adding constant motion to the lower areas of the aquarium.

Long Tentacle Plate Corals are best placed directly on a soft sand bed where their delicate tissue has room to fully expand without rubbing against sharp rockwork. With moderate lighting, gentle to moderate water movement, and stable reef parameters, they can become an impressive centerpiece in both established and developing reef aquariums.

Placement & Care Tips

Place your Long Tentacle Plate Coral on an open area of the sand bed with plenty of space around it. Avoid placing it directly on rockwork, as its soft tissue can become damaged against sharp or uneven surfaces as the coral expands.

Provide enough water movement to gently move the tentacles without causing them to whip aggressively or remain retracted. Occasional target feeding with appropriately sized foods such as mysis shrimp or other quality reef foods can help support healthy growth and coloration.

Because Long Tentacle Plate Corals can sting nearby corals, leave adequate space between the plate coral and neighboring livestock.

Why Choose a Long Tentacle Plate Coral?

The combination of long flowing tentacles, impressive expansion, and unusual free-living growth makes Heliofungia actiniformis one of the most distinctive LPS corals available. It's an excellent choice for reef keepers looking for a showpiece coral that brings movement and character to the sand bed.
