Do I need to attach it to live rock?

No, as a solitary coral it doesn't need to be attached to rock — placing it on the sand bed is actually the natural way to keep it. Choose a stable, flat spot for it.

Is it okay to place it near other corals?

When its tentacles extend, contact with neighboring corals can cause stinging damage, so it's best to leave ample space around it.

Will clownfish always host in it?

Clownfish may take up residence in it, but this isn't guaranteed. It depends on the individual fish and the tank's conditions.

Does a shrunken tentacle mean it's unhealthy?

Tentacles can retract when flow or lighting is too strong, or when feeding is insufficient. Review the tank conditions and try feeding if needed.

Can beginners keep this coral?

This species is considered suitable for intermediate keepers, so some experience managing flow, lighting, and water quality is reassuring. It's best to get comfortable with basic coral care first.

Heliofungia (Long Tentacle Plate Coral)

Heliofungia, also known as the Long Tentacle Plate Coral, is a solitary LPS coral with long, anemone-like tentacles that sway gracefully in the water flow. Unlike colonial corals, it lives as a single individual and is typically placed directly on the sand bed rather than mounted on rock. Its flowing tentacles create a striking visual focal point in any reef tank, and it's not uncommon for clownfish to take up residence within them. Keeping this coral well calls for intermediate-level experience, but it rewards patient keepers with a lifespan of 10 years or more, eventually growing to a substantial 15-30cm across.

About Heliofungia (Long Tentacle Plate Coral)

Heliofungia (Long Tentacle Plate Coral) is a solitary LPS coral with long, anemone-like tentacles, kept on a sand bed. An intermediate-level species that clownfish sometimes inhabit.

7 things to know before welcoming a Heliofungia (Long Tentacle Plate Coral)

1Best Kept on a Sand Bed
This species has a solitary skeleton that doesn't attach to rock, so it's kept on the sand bed rather than live rock. Choose a stable spot away from strong direct water flow so it won't roll around.
2Mind the Long Tentacles
When extended, its tentacles can sting and damage neighboring corals on contact. Leave plenty of space around it when choosing a placement.
3Moderate Flow and Light
Excessively strong flow can cause the tentacles to retract. Moderate lighting, rather than very intense light, helps the tentacles extend and spread more freely.
4Occasional Clownfish Hosting
Clownfish sometimes take up residence in it as a substitute for an anemone, but this isn't guaranteed and depends on the individual fish and tank conditions.
5Feeding Supports Condition
When the tentacles are retracted, offering plankton-type foods or liquid feeds can help it recover. Adjust feeding based on how the coral is doing.
6Suited to Intermediate Keepers
This coral is considered suitable for intermediate keepers, requiring experience balancing water quality, flow, and lighting. It helps to have basic coral-keeping knowledge before bringing one home.
7Plan for Long-Term Care
With a lifespan of 10 years or more and an adult size of around 15-30cm, it's worth planning your layout in advance with its future size and spacing from other corals in mind.
