If they start running out of food I might have to resort to adding bait fish, I can go cast netting for a day and get hundreds of fingerling mullet to add to supliment food also. but I am following you, Cant add to many big fish eaters in a little pond.
It has no aration, I did however raise up the outflow pipe of the well water a couple feet about the water line to allow it to splash for better airation.
