Vine like super-algae. ID Please

[Simsung]

Hello,

I am battling this alga for the past year and a half. It seems to be coming back no matter how hard I hit it.
At one point I took all the rock out, spent 5 hours picking it out off the rock but it came back eventually.
I tried vibrant and it slowed down considerably, but it never went away.
When I thought its gone, I added a bit of Cheatogro and it is back again.

I want to get a fish that will eat it (if one exists?) but first, I need to ID it.

Does anyone know what algae is this?

Thank you!

Caulerpa I think. Pretty common in fuges but I've always heard it warned it could go sexual and be very destructive.

Best guess

Hmm, I looked up the Caulerpa, and the Serrulata resembles it.

Best guess

I think that is it, nothing else in the caulerpa family is even close.

Pretty sure it’s Caulerpa brachypus.

Looks like either Derbesia or Taxifolia Caulerpa
