Sebae Anemone

Sebae Anemone key facts

Care level

Advanced

Size

Oral disc 20-50 cm, tentacles 10-15 cm

Temperature

22〜26℃

Diet

Nutrition from symbiotic zooxanthellae, supplemented about once a week with meaty foods such as fish, shrimp and clam.

Lighting

Care tables for this family list lighting as high. It depends on its zooxanthellae and needs strong illumination; bleached specimens have lost their symbionts and are difficult to recover.

Flow & Placement

Flow should be moderate. It prefers hard substrate lightly covered with sand, and in the aquarium it usually wedges its foot where the rockwork meets the sand bed.

Water Temperature & Quality

Water 22-26C, specific gravity 1.020-1.025. It is difficult to acclimate and needs a mature tank with stable water chemistry.

Feeding

Besides photosynthesis, offer meaty foods such as fish, worms, clam and shrimp about once a week. A healthy specimen is very sticky to the touch.

Notes

The name Sebae Anemone is also applied to Radianthus malu, so check the scientific name when buying. It is not listed in the CITES Appendices.

About Sebae Anemone

A striking host anemone with a wide oral disc and purple- or blue-tipped tentacles. Known to host up to fifteen clownfish species, it demands experienced care.

7 things to know before welcoming a Sebae Anemone

1. 1Needs Strong Lighting

   The Sebae Anemone relies heavily on photosynthesis from its symbiotic zooxanthellae for nutrition. Strong lighting is needed for the oral disc to fully expand, and insufficient light can cause it to shrink or lose color. Check your lighting setup before bringing one home.

2. 2Provide Steady Water Flow

   Moderate water flow helps the tentacles spread and drift naturally, but flow that's too strong can damage the oral disc. Aim for varied, gentle-to-moderate currents in the tank and adjust based on how the anemone responds.

3. 3Sensitive to Water Changes

   This anemone is sensitive to sudden shifts in temperature, salinity, or nutrient levels, and can be easily stressed by rapid changes. It does best in a well-established, stable tank rather than a newly cycled one。

4. 4May Wander to Settle

   It's known to move around the tank until it finds a spot it likes. Because it can get caught in pump intakes or wedged in rockwork and injure itself, it's worth blocking off any hazardous areas in advance.

5. 5Clownfish Symbiosis

   The Sebae Anemone is known to host up to fifteen species of clownfish, and watching this symbiosis is one of its main draws. That said, not every clownfish will pair with it, as compatibility varies between individuals.

6. 6Handle Tentacles with Care

   Its tentacles carry nematocysts and can cause a mild stinging sensation on direct contact. Wear gloves when handling it, and give it enough space from other corals or anemones to avoid contact.

7. 7Best Suited to Experienced Keepers

   This species is demanding when it comes to lighting, water flow, and water quality, and is considered suitable for experienced keepers. It's best to have solid marine aquarium experience and a well-prepared environment before adding one.

Frequently asked questions about Sebae Anemone

Q.Is this suitable for beginners?

A.The Sebae Anemone has demanding lighting, flow, and water quality needs, and is considered a species for experienced keepers. It's best to gain some marine fish and coral keeping experience before adding one.

Q.How big does it grow?

A.The oral disc can spread to roughly 20-50cm across, with tentacles around 10-15cm long. It becomes a sizeable, eye-catching presence in the tank.

Q.Which clownfish will host in it?

A.It's known to host up to fifteen species of clownfish. That said, pairing isn't guaranteed with every combination, as compatibility varies by individual.

Q.What lighting does it need?

A.Because it gets much of its nutrition from photosynthesis via symbiotic algae, it needs strong lighting. Insufficient light can cause the oral disc to shrink or lose color.

Q.Can it be kept with other corals?

A.Its tentacles carry nematocysts that can sting and damage neighboring animals on contact. Since it may also wander around the tank, give it plenty of distance from other corals and anemones.
