and there is the lights out critters

[MercerNoob]

I don't know if they are the common bristleworms or fireworms (hope it isn't this) but there is a few of them lol like 4 or 5 also this came out at night it looks like hair or something lol (hair algae maybe I donno wasn't there before though. then last picture is the starfish that's in there think its eating the coralline algae it will probably be removed.
the last thing I just found is a bug I think lol sorry it moves so fast pic is bad

after looking through many hitchhiking guides I cant tell what the worms are or the hair stuff maybe Aiptasia? the bug I think and I am pretty sure is a gammarids
