Firstly, I wanna move my oscar outta my 6ft by 3ft thousand litre tank. He is terrorising my pacu. Which in turn upsets the whole balance of my tank. The thing is I only have an empty 60 gal to move him into. I am loath to move any fish into a small tank, but he is damaging him self when the pacu bolts and he gets slammed into the glass if he is near the top or sides. And he isn't stopping. Would he get depressed if I moved him? When they aren't fighting, or when they scared like when I dig in tank, they are always together side by side. They have grown up together from inchlings, I separated them for a little while when the oscar was 6 or 7 inches, and he seemed to get depressed with only catfish companions. Would you say I should move him? Or just leave him.
