Help ID a mystery macro... Seems to be melting

[ackshee]

Does anybody recognize this species, or even have a guess of genus? Under natural lighting it's greyish brown, and translucent. Under the blue reef lighting, it glows red.

I received this macroalgae as a freebie from my local fish store. Unfortunately it seems to be melting a few days later, it's losing its red color. I want to ID it so I can try my best to save it. Thank you.

What fish store did you get it from in Portland? World of Wet Pets?

I've been calling it Acanthophora sp.
Seems to be super variable in terms of color based on lighting.

Strong white lights makes it a dark grey while blue reef light gives it a strong red coloration.

Delicate and highly palatable. Fast grower for me.

I do grow it under high Par and nutrients. It prefers ammonia over nitrate.

Always have some to trim if you want to try it fresh.

Wow thank you so much for the quick and informative reply.

I got it from Cuttle Fish & Corals. That's the only reef store I've been to in Portland, so far. Is World of Wet Pets your go-to?

Just assumed World of Wet Pets. I frequent all the fish stores in Portland, especially Cuttlefish.

Gotcha, thanks. I will probably run into you there sometime. I have been stopping by almost every weekend.

I've bought some that was looked similar and was red. Sold under the name

Red razor Algae | Bryothamnion triquetrum​

Is that how red yours got under the blue lighting?
