It looks like a form of calupera to me. I've had it before, and now, LFS guy suggested a foxface, 6 days later, nearly gone. Just my opinion, someone else who knows more than i do might have something different.
It is indeed a type of caulerpa, but with that size of tank your only bet is to start pulling it out. It will start to overrun your tank quickly. Herbivores will quickly make a meal of it, but like you said the good ones are too big for that size of tank. Keep it manageable if you want it to stay, or pull it out if not.
