Hi.. From my experience, Jardini is harder to com with other Aros. They always start fights and can be a mean bully to other smaller fishes. If you want to keep other fishes with your jardini, just make sure the other fishes are much bigger.
dont put anything in with ur jardini, best thing that u could do. i had my 7" jardini in a tank with a 2" texan cichlid for about 3 wks, until i came home one day to find my jardini basically tore to shreds
y didnt i just keep him in a tank to himself
