Not sure if this is Aiptasia or not. its a very bright teal green. I had Aiptasia before, years ago, but it was a dull tan and ugly. this is actually kinda nice looking but seems to be growing and spreading. Might need to get a peppermint shrimp.

It's not aptasia. Picture is blurry on my phone. Could be colonial hydroids or FD I can't tell.
Lots of reefs have these. There unsightly and often show up with other algae as its believed they are excess nutrient delivered. Managing import typically keeps them in balance.I think you’re correct. I looked up Colonial Hydroids and it does resemble it. The question now would be is it harmless?
Searching online I haven’t been able to find a reasonable way to get rid of it, so if it’s relatively harmless I’ll leave it alone.
I can’t just remove the rock. It’s in several different places on many different rocks most of which are fairly large and are supporting other rocks. Beside, the only way to be sure I got it all would be to remove all the rocks.
Not sure what I should do. Any advice?

I’ve personally never dealt with hydroids before but I’ve heard that they tend to disappear on their own & that peppermint shrimps will also feast on them like they do with aptasia.
