Wanted: Caulerpa prolifera and maybe C. crassifolia

That's entirely possible. Every site I posted ID threads on has had a different opinion. All I know for sure is that it's pretty and grows very quickly, given the right conditions. It volunteered after I upgraded my lighting. Desperately needs to be pruned soon, so if no-one here is interested, I'll be dragging in a bunch of it to Colby at Elite to go with the other stuff I often sell him.
