I've always kept my jardini with tank mates big cats , birchirs as mentioned work well , maybe one or two tuff cichlids from a young age along with some ditherer fish to attract some of the attention but expect casualty's most jars go crazed killers once hit 10"+ unless the tank mates can handle it they won't last long once it starts
As for bass I've tried it they didn't last I've found bass to be very weak when it comes to constant jardini bullying , unless there loads bigger than the jar and then you run the risk of the jar being swallowed or eventually catching them up in size then over powering them
I've never kept Asians but I've got mates with some , some of them I've noticed like my mates rtg excepts tank mates that are smaller than him or pose no threat for tank space like clown loach , rays and cats but like jardini will still fight for upper level territory with cichlids , bass
Yet others I've seen are fine with everything people decide to house them with
I guess its a case of trying tank mates out as each aro's behaviour is so different
