There are three smaller ones and the larger original colony. The small pieces are each about 4"x6" the main colony is about 6"x10". Its a scroll type hammer so a bit harder to break down into small frags hence the large pieces to rehome. I had to do some re-aqua scaping a while back to deal with it as it was starting to crowd the front glass. It is a lot of green right now, I'd like to get some more colour variation once I free up the space. The GSP is another battle to keep from overtaking the whole tank.
I guess excessive coral growth it is a good problem to have.
