same biotope, yes.. unfortunately for us their biotopes tend to be a little bigger than 6x2x2.. they might be fine until the jar hits 8-10" if the jack haven't snapped before that..
there is always the off chance it works but browse the arowana sticky threads and all the failed attempts to com jardinis.. multiply that by another aggressive fish and your odds are thinning even more.. sure, if you buy 20 jars and 20 jacks you could get a couple that works but the logistics will be hell..
