I have a jardini with a pbass together in the same tank and it doesn't work. The jar keeps bullying my pbass though the jar is only around 2cm longer, not mentioning the thickness of the pbass. Thay are both juvenile, the jar is around 11cm and the pbass is around 8cm, I've heard the jars often gets their aggression when they are around a certain length, but this should be way too soon, any idea why the jar turned so aggressive so suddenly??? It can't stand the pbass but it ignores my panaques.
