Please help me pic a new fish!?

My tank is cycled and 2 clowns are coming out of quarantine, so eager to start QT on another addition.

I'm trying my best not to impulse buy

Online sales isn't a big thing in my area. So here's what the LFS got for sale.

Keen to hear if anything stands out / anything that I should definitely not get at the moment.
Down the line I 100% want to get tangs, which I'm not too sure of yet. Also not sure when the best time is to introduce them?

Kinda had my heart set on an Emperor Angel, but the more I read the more I think it might be a bad choice.

FYI, don't have any inverts / CUC yet.. Tank is 180g.

Fish:
Orange Spot Goby / Six Spot Goby
Juvenile Emperor Angel (Look amazing, but worried it's going to eat my corals later on?)
Purple tang ( $$$ )
Black Cap Basslet / Chalk Basslet / Tabacco Basslet
Midas Blenny / Klausewits Blenny / Red Scooter Blenny
Purpel velvet wrasse ( $$$ )
Flame Cardinalfish

Inverts:
Banded turbo snail
Cleaner shrimp / Fire shrimp
Scarlett reef hermit crab
Porcelain anemone crab
Arrow crab

Thanks all!

If corals, no emporer. Also borderline on tank size long term anyway for that guy.

Purple tangs can be jerks. I want one, but I cannot bring myself to take the risk.

Others all look good to me.

My fire shrimp is awesome, dude loves to eat. The color it adds is also a huge plus.
