Im new to the forums, and I would like to know what kind of predatorial fish can fit in a 55-60 gallon tank (fully grown). Arowanas, flowerhorns, and clownknives are out of the picture
. I would really appreciate answers quickly because im getting either of the tanks in a few days. Thanks in advanced!
