need an upgrade any idea?

[Sir-KS]

i was thinking a 55 GAL 48 x 12 x 21.

2 oscars red & albino both about 5 inches and 1 silver arowana about 5 inches

Equipment ---> black sand bottom
fluval 305
aqua clear 50

a 55 wont be big enough for the oscars and a silver arowana will need like 125gal i would say you need a 200 atleast
