Olive Green Critter a Friend or Foe Please? :)

[Colorz]

After searching in here for 3+ hours to identify this, it's time for my 1st post in hopes you can help me figure out what it is

AIO 28g nano is 2 months cycled, live rock, 2 clown fish, cleaner shrimp currently.

Showed itself 4 days ago...
Olive Green color, about 1.5" seems to have grown spike looking pieces off main body which I've seen a few pieces of sand on them.

Any advice is greatly appreciated!!!

So the green thing is actually an animal and not just some sort of algae?

i think it’s bryopsis

That looks like a piece of caulerpa, macro algae.

Have zero clue and hoping to figure it out with this post

Looks like something I would just pluck off with a tweezers and hope it doesn't show back up.

Some type of macro algae. As said above, it looks like calurpa.

Just snagged another pic! Looks like it has an open tube appearance. Base of it goes further under rock than I thought! Still holding a few pieces of sand on its 'branches'.

It’s caulerpa , roots are starting to take hold , keep or remove will take over tank slowly unless trimmed
