I have 3 anemones in my tank the latest addition a H.Mag. The Mag. seems happy until the condy is in its full glory and has spread out its full 12". Then the Mag. starts to move, chemical warfare it seems. I want to remove the large condy I have, but it is very much attached to a very large supporting rock at the bottom in a crevice. How can I get rid of him? .
