The rocks are big enough that I cannot remove them all. In addition, they are infesting my refugium, which I think provides me with a constant supply. The nudibranch option sounds enticing.
I remember reading about those nudis (Berghia Verrucicornis) a while back in Coral magazine which had a great article about culturing them. Thought about trying to do it, they seem to reproduce easily and bookmarked this webpage as part of my research.
There is a ton of info out there on these guys. One thing I do remember about my research is that size is important with these guys, and there were suggestions you get the 'biggest' one you can as they seem to fare better with the strong currents in a reef tank. The smaller ones can get blown around.
Has anyone tried putting a rock covered with them in a micro wave oven? I haven't, but it seems like it would do them all in. I don't know what it would do to coralline algae. Anyway it's just a thought.

The best thing ive seen and used is a copperband butterfly they usally start with tiny fan worms then hit the Aiptasia till its gone , I have not seen the coperband do any damage to any corals at all, the down side to this is the coperband will usally die after all the Aiptasia is gone they starve to death, I have had 2 and cant get them to eat anything after they are done cleaning the tank. Also I have majono cant figuar out how to get rid of that as the copperband wont touch it, as for the myth Like I said I have had 2 nither will touch my LTA or corals.
