Bartholomea annulata
One of the commonest sea anemones on Caribbean reefs. It is recognised by its translucent, corkscrew-twisted tentacles, favours soft sediment and seagrass beds, and frequently hosts commensal cleaner shrimps.
Bartholomea annulata is an anemone in the family Aiptasiidae, ranging from the Caribbean Sea and Gulf of Mexico into the western North Atlantic. It is one of the commonest anemones on Caribbean reefs, and its English names ringed anemone and corkscrew anemone refer to the long, spirally twisted tentacles marked with rings of nematocyst batteries. It is not brightly coloured but is a ghostly, pale translucent animal, and that translucence and tentacle form are its appeal. It prefers soft sediment and areas with seaweed or seagrass over hard rock, so it suits a planted refugium better than the display tank. Cleaner shrimps such as Pedersen shrimp often live with it. It is easy to keep, but the family also contains Aiptasia, and like that genus it can multiply to the point where removal is difficult, so its spread must be managed.

The ideal temperature for the Curlycue Anemone is 24〜27℃.
Origin
Western North Atlantic (Caribbean Sea, Gulf of Mexico, West Indies)
Temperature
24〜27℃
Photosynthesis via zooxanthellae plus meaty foods
It carries zooxanthellae, so moderate lighting is enough; intense light is not required.

Cnidarian sea anemone (Actiniaria, Aiptasiidae). Not listed by CITES because it is not in the stony coral order (Scleractinia). Not designated as a specified invasive species. Like Aiptasia in the same family it reproduces readily; manage its spread in the aquarium.

Give moderate flow and offer soft sediment or seagrass where it can bury its base, rather than bare rock.
Hold 24-27 C and 1.022-1.025 specific gravity steadily; it dislikes sudden swings.
Besides photosynthesis, target-feed minced fish or shrimp onto the tentacles to keep it in good condition.
Like Aiptasia in the same family it spreads readily. It stings, so keep it from touching other corals.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
