i got a new malaysian green arowana for my 90 gal and my silver is fighting him. the malaysian green doesn't fight back and lets the silver attack him. the guy i bought him from had it with other species of arowana (no dither fish) rtg, super reds, silvers and jardinis (all juvenile 5 - 7 inches) in 600+ gal aquarium. they all seem friendly with each other. will the fights stop and will the damage to the fins heal? what would you guys suggest i do. the malaysian green is about 5-7 inches and the silver is about 12+ inches.
