I personally would go 1 or 3(edit ^ he beat me to it lol) unless those two are already fine living together somewhere else..(Judy's blues?)
But honestly I'm only saying that if you really want a blue. Because if you really want a jardini I would probably take my chances as long as I have an exit plan for it if it doesn't work. I would think by 10-12" you should have an idea how your jar is acting, and around that size should be easy to get rid of if it don't work.
