It's like we're sharing a brain, lol
Looks like a hair algae possibly byropsis but hard to tell from that picture..
Look into peroxide dips and zoos.. it will cure it for ya!
How old is your tank? Algae will grow regardless, but you really don't want it irritating your coral...
It's fairly new, so I'll Google a bit and look for some tutorials on how to dip the zoas in H2o2. I imagine for the night it will be alright, or so I hope haha.
You’re fine.. it might eventually spread but it’s not something that happens over night.. those are hard to remove from a frag plug but any lps or Sps it’s best to ditch the frag plug and glue them to rock rubble or a rock etc.
That's good to hear. I broke away some of the frag plug, but was being super cautious as not to damage the zoa. I chipped away some of the frag part (the white part exposed is where I lessened the disk), but I was hesitant to chip away anymore, as I didn't want to damage the zoa.
There are a few others, but to your point, some coral won't tolerate any H2O2 unless its so diluted it's lost it's effectiveness on algae. Very generally speaking, soft corals are the most tolerant, followed by *some* LPS, and then the rest of the lps and SPS. Chalices and hydnophora, for example, can almost melt if you get too strong of a solution on the flesh (ask me how I know
). And obviously, don't use on anemones or feather dusters.

I have some zoas that were in pretty bad shape after being stuck in shipping for over 2 days. I dipped the zoas in full strength 3%. Most of them recovered within a few days but a couple are just now opening, weeks later. Pretty tough corals!
That's incredible, appreciate the anecdote! Didn't realize a couple of weeks was even a thing. Here's hoping! Mine have a couple of heads that are starting to open again, but most are still closed.
