the juli is asserting itself - africans in particular will work hard to establish where they rank on the social scale in the tank. They may settle down given time. You could add some more rockwork in there - get one side of the tank completely piled up. If they havn't settled down a bit in a couple of days re-arrange it. The juli is associating itself with the whole tank at the minute and if you get more rockwork in there it may focus on a more limited area to protect.
you may of course just have a bit of a character in the juli and might have to exchange but give them a few days before you decide this.
