A few questions about some corals I won on a raffle

[arc.flash788]

Hello! I won four corals from a raffle on Facebook, a colony of stargazer zoas, orange acan, Superman monti, and a galaxea coral. Everything that arrived looked alright besides the galaxea. Do you guys think it looks dead or do you think it can come back? Another question I have what in the world is that long skinny hitch hiker? It doesn’t look like a bristle worm to me and I’m going to assume the other bug looking hitch hikers were amphipods? My tank is only a month old so it’s still in the new stage. I also have a 10 gallon nano reef tank that I’m going to drain and redo to make a bare bottom qt/frag tank. Also let me know what you think of this coral placement, they arrived last night and I didn’t have a lot of time to put them in the tank. I’m thinking I need to move the acan closer to the bottom.

-thank you!

I forgot to ask what that reddish thing is growing off the monti frag plug. I think it’s some kind of macro algae but if anyone knows any more let me know
