Do they normally do this, or is it a sign of a problem? Mine grew large, and is now dropping "branches" left and right. All the polyps are open. I'm assuming this is just their natural means of spreading?
I was wondering how agressive they are... if it happens when I'm not around and the current carries them onto other corals.
I think only my zoo's and xeniids would be in it's path, but there are other corals if it gets blown off the bottom
I've never had any issues with the effect on other corals aside from the capnella colonies growing and casting a shadow. I do keep this coral in my tanks even though in my opinion, it's a very pretty coral, but it's also a weed and needs to be kept in check.
