2nd school for 29 gallon

[kiwi35]

So my 29 gallon has been sitting at half stock for awhile and I was looking for help. I'm wanting to add a second school. The current stock is a small gbr and 8 harlequin rasboras. My first idea was to add a school of 6-8 cories and bump up the harlequin school to 12. Another thought was to add 8 schooling fish of some kind, I like the look of serape tetras or black skirts but didn't know about size/aggression issues. My girlfriend is a major fan of tiger barbs but those are simply too aggressive right? So any help?

Have you thought of pentazona barbs? They look extremely similar to tiger barbs but are quite peaceful.

Had never even heard of them before, nor have I seen them at any local stores so those are probably out for me

They are sometimes called Clown Barbs at pet stores.

Emerald eye or neon green rasboras are small and very peaceful.
