What fish should I add next?

[cimulation]

I have a 180g tank that's been running for about 6mos. now. I currently have
2x Mocha Clowns
1x Blue Green Chromis
1x Powder Brown Tang
1x Chocolate Tang
1x Tomini Tang

I'd like to get more Tangs and Wrasses, maybe a Purple Fire Fish or Royal Gramma. I'm just not sure which one to get and what order to add them in. What are your thoughts?

Get the one you want most. You shouldn't have issues in a 180g tank with only those fish.
