it has all the 'charecteristics' of an anemone as far as feeding. That being: tentacles, stinging, grabbing, meat-eater.
Supposedly it will grab whatever walks by, but I have never had any fatalities and mine is in a tank with very susceptible prey such as hermies, snails, nudibranch, pompom crab, and my late mandarin.
- just like a anemone but in a tube, and doesnt need light. (thats the short version)
