The Long Tentacle Anemone is also referred to as the Corkscrew Anemone, Sand Anemone, Red Base Anemone, and Long Tentacle Red Base Anemone. It has a similar appearance to Heteractis crispa, which has more tentacles and a tougher column. Its oral disc is usually visible and can grow up to 20″ in diameter. Its tentacles are spaced further apart than other similar anemones. It is found in various forms and color patterns, but its base is usually orange to red. It is a host to Clownfish, usually Amphiprion perideraion or Amphiprion clarki.

The Long Tentacle Anemone requires an aquarium with 4 inches of sand or rubble substrate in which it can hide.

The diet should include small pieces of fish or mussel, crustaceans, and frozen foods.

aquariablog’s take: I just got one of these guys. Be aware that many will caution you on adding one to your reef systems as they can “wander” the tank looking for a happy spot…stinging your corals along the way. I specifically cleared an area for mine at the bottom-middle of the tank and played with the water flow so that he’d find his way there and be happy. He hasn’t moved an inch so far and is beautiful. My Sexy Shrimp have hosted him and spend most of their time on or around him.
