I'm with the Capn on this one. In the middle of this pic you can see the torch under the xenia. Since this picture was taken the Xenia has moved all the way to the tip of the rock to avoid being stung.
On the left you can see muy anchor and some blue shrooms next to it. Although it doesn't look like it, they are about 6 inches apart and the srhooms still get stung once in a while.
The anchor and torch are my most aggresive corals to date. The only other thing that's doing a lot of stinging in my tank is the apstia infestation I've been working on.
