What is this?

Here is a pic.

Appears to be some sort of algae or bacterial growth. Any chance you could get a pic with just the white channel on? Might help get a cleaner shot

Here you go.

Looks like there is clusters of polyps? If so then those are hydroids. Look into fenbendazole and let's see if anyone from #reefsquad will chime in to confirm

Hydroids

 

[Aidanwolf]

Should I do anything about them?

Yes. Look into fenbendazole. They can/will spread.

I was read peppermint shrimp might help, but I have a CBS so the peppermint shrimp would probably end up as food lol.

Would it effect zoas?

Peppermint shrimp will not eat hydroids.

I don't know if the is a viable option, I have tons of cerith and nassarius snails. I couldn't imagine taking them all out.

This is one of the tough decisions to make in the hobby. You might not be able to "imagine" taking out all your inverts, but sometimes measures like that are necessary.

There is a very slim chance a pep might do something if you starve the tank completely.

You could also try a butterfly fish.

There are some varieties of nudibranchs that might eat hydroids.

I've heard that aiptasia eating filefish MIGHT eat them.

You could make a mag/kalk paste and smother them with it.

Get a very powerful laser and burn them off.

Manual removal is also an option, but they can sting and will most likely spread more after being scraped or scrubbed.

Thank you for helping out.

I've had Pepps eat hydroids. It's not a definite, similar to them eating/not eating Aips, but mine wiped out the same species of hydroids the OP posted.

Makes me want to start a pest tank just to raise Peps to eat all the nasties. I know it can be done if there is little to no other food sources available.
