Can clownfish kill coral?

Ya, never any guarantees with BTA, but I've had one in my tank for close to 4 years & it has moved, but never very far. Early in the game it moved behind, almost under the rock I placed it on & after about a month I had to turn the rock, otherwise it would have wasted away due to lack of light. That was a pain, since the rock was supporting others & most everyone knows what happens when you start shifting one rock....

It has split a number of times & has always hosted a Maroon, first a single, now a mated pair. The original BTA & one clone are still on the same rock, I've sold or traded at least three other clones. Things that will help keep them in place IME are, as mentioned already, a slight depression or hole for their foot and probably also a clownfish partner. The original BTA I have shifted again just recently, not sure why but possibly due to some nudging by my Maroon female. The pair has been spawning for some time now & quite often will encourage the nem to make room for the spot they select to put down the clutch of eggs. Just as I was starting to get a little nervous about where it might end up, it stopped shifting, not all that far from the spot it's been anchored on for a couple of years. I have two VorTech pumps & they would no doubt make short work of a wandering nem that got too close.
