I have four 6"-8" Oscars that have grown up with each other for the last 6 months in a 150gal. For the last couple of nights an I mean nights 2 of my Oscars have been fighting very,very seriously I am only sure of one of the participant's because of the disturbed scales on the forehead. What do u think is causing this and how to get them 2 stop because it is very violent and all the splashing in the middle of the night is keeping me up !!!
