Why no Zoas or Clams?

[Raf]

they are nasty, we had to remove one from a clients tank and it involved removing the suspect rocks from where we thought it was hiding, dosing the rocks with soda water to bring the worm out and making sure all of the worm had been removed by chipping the rock apart where it lived. A big job but a must if you want to keep those corals...

I know snails did kill one of the clams. Sucked it out from the foot.

The Zoas I don't know.
