I live in Florida and have inherited a small pond, maybe 500 gallons with 5 koi in it. It's been very hot and dry for the past week or so, and I recently replaced the pond filter with the same brand and size as the previous one. The pond has a waterfall, but water temp has gone up since the hot and dry weather has persisted.
For the past 3 days, all of the koi stay on the bottom of the pond and in the shade, which I understand, but they are also not eating. I had the water tested and all levels are normal and healthy. I even loaned the pond my beach umbrella to provide some shade for the koi, but they are staying right under the waterfall, completely hidden. I try to give them tiny amounts of food every day, but I don't see that they are actually eating it. How long can they go without food, and what (if anything) I am supposed to do for them?
