Can you post a pic of it?
Where did you get it from?
Are you sure it's not a sand dwelling anemome?
Mine tumbled around for a day or two till he found a nice quiet corner with little flow. He's now buried his foot in the sand and is as happy as a clam
"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 and A. clarki.
The Long Tentacle Anemone requires an aquarium with 4 inches of sand or rubble substrate in which it can hide."
