Plant/Algae ID please

Can anyone identify this plant/algae that's growing around my Palys and if I should be worried about it? It looks kinda neat. . .

Looks to me like Caulerpa Serrulata. Like most caulerpa's it can be invasive, I had it in my Macro tank it just took weekly trimmings to keep it at bay. If you dont want to have to put in that much work on keeping it at bay, then I would remove it.

Thank you!! It's just a small patch and easy to contain.
