Hey guys, I have a 120g that is heavily filtered and I do 80% water changes a week. I currently have a Jack Dempsey, 1 Convict, 1 Salvini, 1 Firemouth, 3 Silver Dollars, and 3 Burmese Border Botia Loaches. All the fish are under 5inches. I was wondering if I could add 1 small Albino Tiger Oscar to this tank to round it out. I know this maybe pushing it a little on stock, but I keep up with water changes, and my water readings are always on the money. What do you guys think? Thanks
