I just freed my purple hasian anenamone today. I have a polishing filter in my 55 gal, and it was half in it. It was horrible. This thing is great to see. It is about 8 inches fully out and I came home and it was almost completely in the filter. I gently worked with it and it finally let go. I immediatly fed it gumbo because it was not moving at all and it was as good as dead. An hour later it is wide open.SHEEEWWW. Just be gentle and I think the trick was feed it immediatly, gave it strenght. "LUCKY" I dont know
