Haven't seen any runners. There's a few single strands that appear to grow from nothing. The photos I've seen of Caulerpa make it look like its a bit rubbery, is it? This stuff I have is very feathery

Just read on Wikipedia that Lettuce nudis arent actually nudis, not even related. They're Lettuce sea slugs (Elysia crispata)

Hmm so spot treatment with Tech M? Could give that a try

yes, the stems and runners are "rubbery" if its caulerpa
