At a glance the quick version
Looks how to spot one
Soft coral (no hard skeleton)
Soft stalks topped with clusters of eight-tentacled polyps that look like little hands. The polyps open and close in a steady rhythm, so the whole colony seems to breathe.21
Personality what they are like
A peaceful coral best known for its constant pulsing. It may stop pulsing at times, and that alone is not a cause for concern.21
Daily activity how busy a day looks
Sessile, but always moving: the polyps pulse to push water away from the colony.2
Grooming and care the hands-on bits
Add iodine and trace elements. It spreads quickly, so give it space away from other soft corals and thin it out when needed.1
Home where they are happiest
A reef aquarium with moderate to high light and medium to strong flow. Stable reef-aquarium water: about 22-26 C (72-78 F), pH 8.1-8.4, alkalinity 8-12 dKH, specific gravity 1.023-1.025.1
Food basics what goes in the bowl
Most of its nutrition comes from the algae in its tissue; weekly micro-plankton or filter-feeder food is suggested on top.1
Company who they like around
Colonial; it grows into dense groups and should be spaced from other sessile animals.1
The story where it all began
Lamarck named the genus Xenia in 1816, and new species were still being described as recently as 2022. Its rhythmic pulsing has made it a favourite in reef tanks, and much of what is sold today is aquacultured.21
Fun facts for the dinner table
- 1
Xenia is one of very few corals that visibly pulse, opening and closing its polyps over and over.2
- 2
Each polyp has eight feathery tentacles.1
- 3
More than 70 Xenia species are recognised, some described as recently as 2022.2
- 4
It can multiply fast enough in a good tank that keepers regularly trim it back.1
Recognised by the official bits
- Taxonomy (via Wikipedia)
- Genus Xenia Lamarck, 1816 (family Xeniidae); WoRMS lists over 70 species. Xenia elongata is one commonly sold form.2
- LiveAquaria (trade)
- Aquacultured Xenia elongata sold as 'Silver Branch Pumping Xenia'.1
The care rhythm Furry Diary remembers it for you
A typical home-care rhythm for a Pulsing Xenia. It is our own starting plan, not a vet's advice, and you can change every line in the app.
- FeedingDepends on species, many feed from the light and the watervaries
- Salinity checkevery week
- Water testevery week
- Top-upTop up evaporation with fresh RO water, not salt waterevery day
- Water changeAbout 10 to 20% of the waterevery 2 weeks
- Light checkevery month
Owner questions the things everyone asks
How often should I feed my Pulsing Xenia?
Most of its nutrition comes from the algae in its tissue, so you only need to offer food about once a week. Furry Diary's starting plan suggests a weekly micro-plankton or filter-feeder food. For exact amounts, check the food label and ask your reef aquarium vet.1 Furry Diary plan
What does a Pulsing Xenia eat, and what should it never eat?
It gets most of its energy from the algae living inside it, and you can offer weekly micro-plankton or filter-feeder food as a supplement. Never feed it anything that could foul the water, like large meaty foods, as this coral is sensitive to poor water quality.1
How much space does a Pulsing Xenia need?
It spreads quickly, so give it plenty of space away from other soft corals and thin it out when needed. In a reef aquarium, a few inches of separation from other sessile animals is a good start.1
What temperature, light or water does a Pulsing Xenia need?
It needs stable reef-aquarium water: about 22-26°C (72-78°F), pH 8.1-8.4, alkalinity 8-12 dKH, and specific gravity 1.023-1.025. Provide moderate to high light and medium to strong flow, and top up evaporation with fresh RO water daily.1 Furry Diary plan
How often should I clean a Pulsing Xenia's home?
Furry Diary's starting plan suggests a 10-20% water change every two weeks, and a weekly water test and salinity check. Also add iodine and trace elements as needed, and thin out the coral when it grows too dense.1 Furry Diary plan
Can a Pulsing Xenia live with others?
Yes, it is a peaceful colonial coral that grows into dense groups, but it should be spaced from other sessile animals because it spreads quickly. It can live with other reef-safe fish and invertebrates that do not nip at corals.1
How long does a Pulsing Xenia live?
With proper care in a stable reef aquarium, it can live for several years, but exact lifespan varies. Ask a good breeder or reef aquarium vet for more specific guidance.
Can I handle a Pulsing Xenia?
It is best not to handle it directly, as it is a soft coral with no skeleton and can be easily damaged. If you need to move or thin it out, use clean tools and gentle handling in the water.21
