I have a brand new 180 gallon fish tank set up ,, I'm thinking about putting in , Jurdini arowanna, 2-4 Asian wild oscars , and one peacock bass . Witch type do u guys recommend . All the fish I mention will be 2-4 inches at first . The pbass I like the most is the diamond pbass (temensis ) because of the spots . I read on different sites that these fish need bigger then a 180 and then when I talk to fish stores they tell me that I would be fine . Please help . I spent enough money on this tank set up and I have no room for a bigger tank
