Green star polyps out of control

[yannicksjh]

Looks like we all have the same problem. I liked it at first, now its got to go. I already got rid of the big piece of live rock it came on, but now i have to remove it from the rocks it jumped to. @ small area's about 3"X3" but i know what that will turn into in month. I had a large clown anemone go over one of them thinkking it was going to sting/suffercate it to death, but NOTHING happen to it. Guest you guys are remending that i should take care of it now!
