what do u do when it gets too big!

[traco]

So, got your attention. What does a person do when a stony coral gets too big for your tank? I have a large red doughnut coral who is definately cramped on floor space. This poor thing extends every day up the front of the glass and under some rockwork. There is no other place to place this coral in my tank.

What do you do? Anyone interested? I would say that fully extended during the day, is close to a foot around. The hard base is about 3"- 4". Very healthy, eats well. Have no reef tank friends so am kind of stuck on what to do about this.
