my rogue cichlid is causing mayhem in my tank, hes taken to chasing the other cichlid to the point where he doesnt come out now and my poor 2 and a half yr old cory is terrified as he is bearing a fair bit of his anger too. i dont have another tank to put it in and really dont know what to do. i cant take it back until tomorrow, should i just float a bag with him in on top of the tank? im really worried that im going to get up tomorrow and find half my fish dead
