Help with identifying algae

[thisguy1]

Wondering if anyone can help me identify this type of “algae” or whatever it is?

That does not look like algae. My best bet would me micro featherdusters, those would be completely harmless but @ISpeakForTheSeas should be able to help too, just in case I'm wrong

Kinda look like hydroids imo, don’t really think it’s algae

Yeah, those are hydroids - you'll want to remove them.
