I have a greenhouse pond,and it gets very warm in there during the summertime.90* plus,even with fans and doors open,although a nice breeze most of the time.
Anyway I only feed my fish once a day,but I offer them water lettuce and hyacinths,which the eat to pieces.
I was wondering if I'm feeding them enough,but I only feed my fish once a day in my outside pond,and there not as aggressive as the indoor fish.
