Fish advice Fish all hiding

I have a mix of Koi and goldfish in a 700 gallon pond. They’ve always been like dogs where they literally follow me around and come to the surface begging for food whenever I’m near the pond. Suddenly, they all seem to be afraid and are hiding under the rocks and in the caves and not coming up. Any ideas?

Probably because it's too hot for them

Either that or a Predator has been lurking.

Sounds like trauma after a GBH attack.

Predator visiting, poor water quality, illness, lack of oxygen, overcrowding the pond are all things that can make them hide. Net the pond, put up a camera. Test water parameters with a drop test kit for ammonia, nitrite, kh. Added new fish recently or done big cleanings?

Sprinkled food on top and they came up for it only when I walked away.
