3/4 type of Caulerpa. Not always bad but I wouldn't have in my dispaly but in a refugium where I could keep it from getting out of control.

These are the right identities, but personally I wouldn't want any of those in my display. Both the Caulerpa and the Halimeda can get out of hand (not to mention the hair algae!! haha), and the Halimeda uses up calcium in the aquarium (it is a calcareus algae as is coralline), and if it's really prolific can actually use up a noticable amount of calcium.
