Mystery Macro ?

[Bpones]

Hi y’all!
I’ve had this macro algae in my reef for years. No clue where it came from but my foxface tends to ignore it beyond the occasional nibble. I have a bristle tooth in QT so it very well could end up being history soon. Curious if anyone has ever seen it or knows what it is.

I may end up rehoming it instead of letting the tang have it for lunch.

It's likely somewhat calcified, so not many herbivores other than urchins are likely to eat it:

the first thing that would come to mind would be an algae from the taxonomic tribe Udoteeae (like the Mermaid's Fan mentioned above) or a species from the taxonomic family Dichotomosiphonaceae.

I'm not familiar with all of the genera from Udoteeae and Dichotomosiphonaceae yet, but I know the genera Avrainvillea, Cladocephalus, Flabellia (this one I know is temperate, so it won't be from this genus), and Udotea all have species that may look at least superficially like this.

I had something much like this, as soon as it got big enough to make a post for ID my halloween hermit ate the whole thing, before I could post :(
Following along for ID

Could be Udotea Sp. (Mermaid's Fan)

Thank you! I just looked those up and I’d have to agree.

Thanks for all the info!

I did put a marble size tuxedo urchin in that tank two days ago so perhaps I’ll move the algae to another tank where it won’t be munched.
