Can 12 Chromis be introduced at the same time into a 190g?

Thanks guys for all the input. I had put 7 in my old 125g and in the end 5 lived the 4 years that the tank was up. I am hoping for the same (I'm figuring 2-3 to die due to pecking order fighting), and figure it would be nice to see them schooling. I hope the achilles keeps them on their toes, as was mentioned, the 5 I had in the past schooled less and less as time went on. I was thinking a shoal of anthias would be cool, but they are picky, have extra feeding needs if you get them eating, and cost a lot more.

Chalk Bass were always one of my favorite schoolers...

Not as aggressive as Chromis but still became an issue eventually.
