well here is an idea and thought.... i still have both my oscar's one tiger and one albino the tiger ive had since he was super tiny like 2" nursed him back to health after a major disagreement with my female JD (which is in a different tank now) i thought what if i traded in my bigger albino and kept my tiger oscar and got fish that were about his size or bigger ? would that be a good idea or no... i dont really wanna get rid of my tiger oscar as i have attachment to him more then anyone else i have lol ... (albino was just a rescue) and the tiger always surrenders to the bigger albino she is the boss in the tank as far as im concerned as she is the biggest outta everyone....
so the tiger is about 9" max, if i got a 12" aro, 12-15" orante bichir, 10" peacock bass, would those be a good size to be ok with together ? or do you advise not to do it ? im just thinking of a ways to possibly keep my tiger if i can as i dont have another tank for him here
