However, crowding reduces growth rates independent of food availability, water quality, and so on.

Are they referring to crowding as in many fish per tank or as in 1 fish in a small tank. I think there is a difference. If the former I agree, too many fish causes reduced growth rates no matter how much you feed and clean. On the other hand, unlimited food availability and a continuous water flow will allow for pretty large size fish in a pretty small tank.
