hey, so im gonna be building a 6.5x3x2 300 gal indoor pond. Im gonna be stocking it with at least my silver aro who will be grown out a little more by then...Im wondering what are some other good fish to stock with. So far im considering 1 to 2 arowanas (1 silver 1 black), 1 to 2 tiger shovelnoses, and a peacock bass, do you think the max setup would work (2 aros 2 tigers and a peacock bass) would be over doing it? what do you guys think?
