pretty much except one little thing well not so little ALWAYS WEAR GLOVES and eye wear. since these guys are toxic they kill hurt or worse case senerio kill you.
you can also add small pieces of rock beside the main colony and they will grow onto the them and then you can cut them away. you can also break the rock up they are on and cut the connected tissues to seperate the rocks.
there are many thing you can do. if you search the threads you can find reefkprz I beleive had a thread about fragging them.
