I was lucky enough to pick up this tank cheap because the owner ordered peninsula tank, so excited to build it and stock it earlier than I expected. Right now I have a 125 gallon I have a 12 inch arowana and a couple 5 inch black bar silver dollar. What else could I add? I am thinking of putting a sump filtration band probably change 50 percent every 1-2 weeks.
