Can I house a 2ft Channa Maurulius ( aka Sri lankan Channa Ara) with 2 , 18 inch alligator gars. I have added the gars fist into the tank and its been a while now. Would the Channa Maurulis attack my gars? The tank I am about to house them is 9ft long, 3.5 ft wide and 4ft tall. Its definitely a temporary tank and I am aware of the huge max sizes both the fish species grow to.
