i realize that but their physical attributes are very similar... with long stinging tentacles, hence the reason I offered up my experience
also, I dont believe that they are filter feeders as mine readily eats large pieces of meat by grabbing them with his tentacles and propelling the meat toward his orifice to be consumed. He also pulls large pieces right out of the water when Im feeding.
I do not think tube anemones are filter feeders, and Im just basing that on their anatomy and behavior. Although I could be wrong.
EDIT: they are filter feeders according to wwm
but again, thier physical attributes are similar to the common anemone, the reason why I mentioned it.
