what they do is at night they perch up on their arms and form a sort of cage and then sit and wait for a fish to think they have found a cozy spot to sleep and BAM! they twist around and trap the fish and shove it in their mouth. I've seen video of them doing it and they have been clocked in the fractions of a second in how fast they can trap prey.

when mine got big, about 14"-16" tip to tip, he would sit in that posture very often and then fish began to disappear, so........
and I found this little guy crawling around the other night. unusual for them to climb the sides of the tank.
I found one in my refugium yesterday that is probably 4" arm tip to arm tip and a body disc about as big as a shirt button. Would get a pic but he is woven into a mass of chaeto...LOL
there are literally hundreds of them all over.....
