You have a very nice pond!
Sometimes fish don't come to eat after something chased them or scared them in any way!
This year for the first time in 16yrs that I have the pond, my koi are dealing with a lot of stress over Bull frogs, if they don't come to me when I approach the pond, that's the first sign that a Bull frog is or has being around the pond.
Not much we can do about Bull frogs but do you have a cover to protect your fish from other predators?
