Hi all. Any ideas what this is? Ive been looking for past few days as getting marks like this on some.of my sps

Looks like a nudibranch to me, but it's kind of out of focus

I am not sure about the coral, but the creature looks like a type of algae-eating Sea slug, maybe Elysia (which is not a nudibranch):

So, all nudibranchs are sea slugs but not all sea slugs are nudis?

Correct! Ex. Sea hares are Sea slugs, but not Nudibranchs.
