I had a datnoid about 4-5 inches and silv. arowana about 8 inches and 2 silver dollars about 3 inches already. Yesterday i just bought 2 monoculus bass of about 3 inches and i am not being able to feed them. I feed my other fishes market shrimp which the bass are showing no interest in also they cant compete with the dat. Should i seperate them with a partition until the bass gets big enough?
