Critter/Algae ID

[wookiefever]

Hello there,

I have noticed some algae in my tank and wanted some sort of ID on it for educational purposes. Also I found a sea star hidden among my rocks and I was wondering if it could be ID. Finally, I see something that resembles a feather dusters but I am not sure...

Thank you so much in advance.

pic 1 looks like an aptasia anemone, pic 2 looks like cyano bacteria (try to siphon it it)... pic 3 and 4 i cant really make out. but dusters are common in live rock, so i wouldnt be suprised, they're small ones that will remain small, they wont turn into the big ones you buy as feather dusters.

thank you so much. I wish I could get the cyano but I am unable to. Hopefully with time it will go away.
