I will be setting up a 500 gallon soon and I want to get silvers. These are generally to expensive so I would rather raise them myself. Should I buy 1 to 2 inch fish and start them in a 55 gallon or would I be better off buying them at 3 or 4 inches and put them directly in the 500 gallon? The big tank would give them plenty of room to move but will a tank that big make it hard for them to find their food? Does any one have experience growing baby silvers to 4 foot or more?
