I wonder if the tweezer extraction was enough for those guys.
I kinda doubt it. They (majano) can be just as pesky as aiptasia in that any portion of it that's left on the rock can regenerate...even "tiny" portions. Maybe you can borrow someone's Raccoon Butterfly for awhile - they will definitely eat the majano, but will also wipe out helpful worms (featherdusters and the like). Berghia won't eat the stuff.

LOL - I may be nutz, but I think majano is kinda pretty - too bad it's a nuisance anemone :roll
