I have a 4-5 inch AT Dat with my 5-6 inch P-Bass and 15+ Silver Arowana. The AT Dat is showing lots of aggresion to my P-Bass. He doesnt let the P-Bass leave the corner of the tank. He also constantly swims under my silver arowana as if using the arowana for cover. My wife says he picks on the P-Bass then runs to his big body gaurd. Is it normal for a datnoid to show this kind of aggression towards other species?
