Overview
What to know before you buy.
Not a true anemone but a cerianthid, living in a buried tube on the sand bed. Its sting is potent enough to take small fish, so it is best kept in a species or fish-free system.
Care guide
Keeping Tube Anemone healthy in a South African setup.
Placement & light
An anemone chooses its own spot and will walk until it finds the light and flow it wants. Cover pump intakes and powerheads first, then let it settle.
Water parameters
Keep pH 8.1–8.4 and 24–27°C, with salinity around 1.025–1.026. Alkalinity, calcium and magnesium matter more than any single reading: keep them stable and test weekly.
Feeding
Carnivore — meaty foods. Target-feed small meaty foods such as mysis once or twice a week.
Stinging & spacing
Powerful sting; not reef safe. Many corals and anemones sting what they touch, some with sweeper tentacles that reach well beyond the colony at night. Leave clear space around Tube Anemone as it grows.
Reef compatibility
Large angelfish and butterflyfish nip at corals and anemones; most reef fish, shrimp and snails leave it alone.
Propagation
Some anemones split on their own in a stable tank; they are not cut.
