Starting to grow everywhere. Peroxide kills it somewhat.

Any fish/CUC that will eat this? I have a cleaner shrimp, various snails (trochus, astrea, and some others), and hermits in the tank.

Hair algae (maybe bryopsis), sea urchin do a great job eating that stuff and yellow eyed kole tang is also very good at handling that.

But my advice is that you attack it from different fronts, mechanical removal, cuc, utility Fish and nutrient balance.

I have a blue hippo and yellow tang in there. They ignore it.
They usually ignore that stuff, there are 4 Fish i know of which i have seen with my own eyes that i know for a fact work and those are foxface (mangifica), yellow eyed kole tang, purple tang and lawnmower blenny. I own these 4 Fish and they all munched down on that stuff until extinction. Main reason why i got rid of my GHA was because of them and now i suspect my cuc is what keeps it at bay.

I’ll look into a blenny then. Thanks.

Keep in mind though, your 2 tangs might get really ticked off at the blenny and chase it like crazy. My yellow eyed kole tang started doing it about 2 weeks ago after 1 year togethur with no issues before that so now my blenny lives in my refugium 😅

Not even the best herbivore will touch it that long. You need to manually remove as much as possible and then the CUC will do the rest.
Usually probably true but I did catch a cerith in my tank swinging from a long bit of hair algae like George of the Jungle recently lol

I think it was actually a stretch they came partially loose from the rock though to be fair

If fish not touching it, it could potentially be Chlorodesmis Fastigiata, they won’t eat it as is toxic for them.
