Brentirwin Posted March 14, 2022 Share Posted March 14, 2022 My Oscar’s been together for over a year and got along ok with some mild bumping but now they straight open mouth jaw locking fights going on is this normal? I moved them from a60 gallon to a130 gallon . My red Oscar pushes the fight with my tiger , that leave my other fish alone. I test my water to make sure they not stressed and all my numbers are good thank you Link to comment Share on other sites More sharing options...
