ok I’m freaking out. We just moved 4 of our koi to a new larger pond yesterday. One of them had a rough entry and hit a rock on the way in but seemed fine for the following hours. Then it started to separate itself from the group and lying on the bottom. It will periodically swim in a circle and then lay on the bottom for a bit, then swim in a circle and lay on the bottom again and so on. It ate some yesterday but shows ZERO interest today. I have put pond salt and stress coat in the water along with Melafix because I was worried it could be a parasite or bacterial thing but there has been no change, she has also popped her head out of the water a handfull of times. The water was clear before adding the fish But has become a little murky. I tested the water quality and it’s good. The other fish are doing great so I’m at a loss. I consider myself a beginner in all this, I’ve had them for six years and only had small easily fixed issues but this is out of my league for sure.
