Lianne, What you are seeing is fairly normal. Like most territorial animals, your fry are practicing for the time when they have to establish & defend a territory of their own. A. panduro is one of the apistos that has little sexual dimorphism even as adults, so at 6 weeks of age I don't think I could sex them.
