How to contain these corals...?

I have had the same problem with all three of those. The GSP overgrows other corals and eventually kills them. And the kenya are notorious for sending branches all over the tank and starting new colonies. I honestly just rip them off now. Same with the GSP take a razor blade and peel them off so you can frag them, and watever doesnt peel off nice i just scrape till its gone. Be careful these corals can over take your tank in a blink of an eye.

Thanks everyone. I'll try to see if i can isolate any of them. I don't have a sand bed so would the GSP grow onto the bottom of the glass?
