So I'm looking to remove a lot of my live rock from my tank, however I have corals that have attached to large bits of rock that I don't want in my new landscape. Can I cut them at the base and reattach to another bit of rock or will this kill them? Some are still attached to their original frag plugs but many are not. They are soft corals, I'm worried if I cut the rock around the coral base they will suffer from being out too long, also I didbt want to attach pieces of rock if I didnt have to. Any suggestions?
