Its a 150gallon with two silver arowana, no fighting.. sometimes they will fight over for food.. but not the the point of hurting each other... occasionally u will see some damaged fins.. but nothing serious.. no lost scales at least..
two four inchers should be interesting.. i've never done it.. i've heard some deaths from it.. mostly jardins.. i dunno about silvers.. but if they are in a big tank.. should be fine..
there are quite a lot of guys here with 2 silvers..there is media lounge post of people with 2 silvers.go check that out..plenty of pics. there is no fighting between my 2 silvers as well.
nice yea the little guys are being pretty good together if there is fighting going on i will get a third for a little while they are going into a 150 here when they get about 6 inches. dont want my 7 inch oscar having a snack right now. they are growning out in a 55 gallon with some angel fish.
