Well fed perch fry can grow 1mm per day. Growth rate slows as they get larger. Females grow faster than the males. Any entire year class of perch at 1 yr old can range in size from 2" to 8.5" often most of them will be in the 4"-6" range. Ample food is important for good growth. Usually the smaller ones will be a large percentage male and largest ones will be females. Expect variation.
