How big do fathead minnows need to be to re populate in a pond? I really only put the fathead in July 1st and they were between 2-2.5"s long. See picture added.
I have thousands and thousands of small clear .25" up to 1" schools of minnows all around the pond. I let the water go again to that greeny blue colour and backed off on the pond dye once I spotted these guys. The first school I seen have doubled in size.
