Arowana1;4010846; said:Bderick67 you may want to put a small Rio flow pump in your tank (a the top) for your Arowanas. The smaller pumps produce a slow water current that I think Arowanas are fond of. Plus with the extra swimming make a 450 gallon into a 600 gallon tank (minus the flows).
Thanks, but I already have 6 different reutrns that are producing current near the surface. Why waste money and energy on rio pumps.
