Bryopsis or hair algae?

[Miami Reef]

agree, those also tell me it's derbesia.
I once convinced myself that my GHA was something different because it was so distasteful to everything and I didn't see those little dark spores. So I emailed an academic phycologist... who sent me a few papers and told me it was just plain old derbesia.
So yeah, I asked a professional seaweed expert to look at ... GHA. lol.

update us on how that tang does with your tank GHA.

Thank you so much!!!

The Desjardini tang needs the algae to be free floating to eat it. It’s not picking at the rocks yet.
I believe with time it will start picking at them directly. For now; I can brush them, tweeze them, and pick them off.

I’m tempted to add a foxface temporarily to help handle the hair algae.

My experience matches yours: most herbivores do not like derbesia.

@taricha

The sailfin (Desjardini) completely eradicated the algae (derbasia)

Best purchase EVER!!

You could charge like 2-3x market value for a fish with that track record :p

I just brainstormed why I have hair algae now and not before. I rehomed my yellow tang recently. I never had hair algae even when I rehomed the foxface after several months.

I had a big patch of hair algae on the stalk of a candy cane. It’s also almost completely gone!

I just assumed zebrasomas = hair algae lovers. I found reports online on desjadini tangs loving bubble and hair algae, so I was sold. I got the biggest one my LFS had. :)

You provided 1/2 the solution.

Now I need a tank large enough for it.

I cant tell for sure in the picture.. does it look like a fern?

That is true bryopsis. I think @Miami Reef is into something else.

It was Derbesia (green hair algae).

The Desjadini tang I added ate it all.

It was Derbasia (green hair algae).

Glad you found a good solution. For me it is as many tangs & foxface as I can house.

Foxface are great, but I already removed 4 in my lifetime because they all eventually ate my trachyphyllia corals.
