Hemprich's Sea Anemone is a large anemone. Its oral disc is covered in fine, branching brown tentacles, and grape-like sticky tentacles in purple and green line the inner edge. The oral disc reaches 20 to 30 cm across, so it stands out in any tank. Clownfish do not host in it, so it is not a stand-in for a clownfish host anemone. It is rated for advanced keepers, and reliable information on its lifespan is limited. It suits aquarists who are ready to learn its needs carefully and give it plenty of room.

About Hemprich's Sea Anemone
Hemprich's Sea Anemone is a large anemone with a 20 to 30 cm oral disc, fine brown tentacles and purple-and-green grape-like sticky tentacles. Clownfish do not host in it. Here is what advanced keepers should know before bringing one home.
7 things to know before welcoming a Hemprich's Sea Anemone
1Advanced-level difficulty
This species is rated for advanced keepers. If you are still building experience with anemones, gather information and get your tank stable before considering one.
2A 20 to 30 cm oral disc
The oral disc grows to 20 to 30 cm across. Plan your tank around the fully expanded anemone and leave plenty of open space around it.
3Not a clownfish host
Clownfish do not host in this anemone. If you want to watch clownfish settle into an anemone, look at other species. This one is best enjoyed for its distinctive appearance alone.
4Mind the stinging tentacles
Anemones in this family have strong venom, and the sticky tentacles grip hard. Never touch it bare-handed, do not keep it in the same tank as small fish or crustaceans, and place it well away from other cnidarians.
5It may change location
Anemones in general can relocate within a tank. After introduction, check often that it is not drifting toward pump intakes, overflows or corals.
6Stable water, daily checks
Sudden changes in water conditions are generally stressful for anemones. Check how open the tentacles are and how firm the oral disc looks each day, and ask the seller about feeding so you can adjust it to the individual.
7Lifespan is poorly documented
Reliable information on lifespan is limited, so no specific figure can be given. Keeping your own records of how the animal does in your tank is a practical way to build up knowledge.
