So I want an Oscar and was thinking about throwing one in a 48"x 30"x 17" tank. I know it is weird dimensions but you work with what you got. I am not worried about the length or width housing one for many years. Especially since I like to buy small fish and grow them out, but would 17" depth be enough for a 12"+ fish. I keep going back and forth on this in my head so I am looking for some advise from you all. How tall is a 12"+ Oscar?
