Possible Hitchhiker?

[djm]

Hi Guys,

I added my first coral to my tank on Monday, a single Rasta Zoa polyp. I did a coral dip using Coral RX Pro and Seachem Reef Dip.
Over the last couple of days I’ve noticed something that appears to be growing out from the base of the polyp.
Any ideas what this can be?

some sort of macroalgae,
possibly a type of caulerpa

Should I be concerned about it, does it need removing?

depends, some caulerpas get out of control if you don’t have herbivores like tangs and such

Thanks for the advice. Only 2 clownfish and a few hermits in the tank at the moment.
