Unknown Brown Hair Algae

[ReeferRobbie]

Hi, I could use some help identifying this brown hair type algae. My CUC won’t touch it. Any ideas? I know there’s a lot of Dinos mixed in unfortunately.

Looks like GHA to me. Light spectrum can make it look brown. Shine a flashlight at it, it's probably green. Most CUC won't touch it once it gets long with the exception of Urchins and Sea Hares. You probably need to do some manual removal as short as possible to get your CUC interested and you probably need more of them.
