It looks like he just tickles them, and off they come. :eek:

if u point a powerhead at them it seems to get them to move or rub an ice cube on the foot (have not done this just read it in the anemone forum on rc)

the ice doesnt work.. its just a hassle. All's I do is take my finger nail, and pry the foot off the rock. BTA's are so hardy , don't worry if you have to get a little rough. In time it will just get tired and let go, and presto... I have done this many times.
