Ideas for last fish?

[bues0022]

I have a 30 cube, and I’m undecided on what I want for my last fish. So far:

 

pair of percs

firefish

hectors goby

diamond goby

 

I really like the different colors/shapes/personalities of all of the fish, but I’d love to have a fish that spends more time swimming in the water column. I have a peaceful mixed reef, so things like dwarf angels are out. I’m browsing fish online, but any suggestions are appreciated. 

 

Maybe a a pair of Chromis? Would and orchid dottyback be too aggressive if I only get one, as I don’t think I have room for a pair?

 

Edit: I don’t care for cardinal fish of any color.

I have an orchid dottyback in our 34gal Red Sea Max and it does just fine with the other fish.  Tankmates are a pair of ocellaris clowns, a pair of neon gobies, a yellow watchman goby, and a miniature foxface.

I had one of these in my 40. Loved it!
It was always out and about. I don't think I have a picture that you couldnt see him in.
