Feather duster (or Aiptasia) and Hydroids?

[reefomatix]

I got some corals from WWC about two weeks ago. I didn't dip them upon arrival as I'm new to corals...

I've kept them in a separate tank to monitor them. Here's what I see so far in terms of possible pests/hitchhikers. If you can please help me identify them and possible remedies, I'd be greatful:

My guess: Feather duster (harmless)?

My guess: Hydroids (possibly bothersome?)?

Should I just scrape these off in tank water (then discard)? Should I dip these? I currently have Bayer Advanced, CoralRx, and Revive if needed.

Lastly, for future reference: can Bayer Advanced be used for Softies & LPS as well (I've previously heard it mentioned several times to be used with SPS)?

Thanks!

First one is definitely a harmless feather duster.

Not sure about the second picture.

1st is cool. 2nd isn't aiptasia so if you aren't already going through a quarantine procedure with you i'd just let it grow and welcome diversity

TheBackAndForth is right

LOL. I just watched this movie again last week. What're the odds...

Scrape all away to eliminate any nuisance hitchhikers

Is this related to the second picture? If so, says they can be harmful to certain corals...

Agree with feather duster on number 1. Number 2 may be hydroids but the picture is not super clear on my end. To be safe, you remove the coral from the plug completely and glue to another plug or rock.
