okay i got 260 gallons maby 300 but that wold only make the tank taller. Right now its planned to be 6 ft long, 2 ft tall and 3 ft wide. I can add another foot to the tank. But im really looking for the smallest species of pbass that i can get. I was thinking Monos, oris, or oces. How many can i put in here? Witch species? And any tank mates? i was thinking of adding like a Gold Saum? or a Uara?
