Wish I had that problem. Have a huge rock with the electric green gap, and some clove polyps on another. Both of which my wife loved and brought home as a gift, when she stopped at acc to buy fish food. the young dude at acc who knew me told her dont do it, hes not gonna like it hah. But she thought he was joking. And well I still have it and the 2 of them laugh about it every time where there. They're like the plague, the gift that keeps on giving in my tank lol. I keep cutting them, smushing them and they just keep on going like the Energizer bunny lol.
I like cloves but another that I cannot keep alive. New tank will probably go softies and try some LPS and bunch of fish and I am done.
