140g tank stocking help

[danskim]

Hello everyone. I'm looking for ideas for tank stocking options.

It's a 140g Oceanic (48x24x29), and currently it has 3 large fish: 1 yellow tang (4"), 1 purple tang (4"), and 1 fairy wrasse (don't know which species, but it is peaceful - 4.5-5").

I was thinking to at least add a small school of green chromis - like 7 or 9 of them. Also, probably a lawnmower blenny, a small goby (maybe pistol shrimp pair), and an ocellaris clown pair.

What other fish would you guys recommend?

Is it going to be a reef tank and what type of filtration and skimming do you have on it?

Yes, a reef tank.
Filtration is done with phosban reactor, asm g3.
