When I feed the fish, I unplug our waterfall for about 2-3 hours (they take their time when eating), and plug it back in after. I fed them late today (around 7:15pm), so when I went outside at around 10:30pm, the three large koi were all grouped around the filter box. One eventually swam towards the middle of the pond, but two stayed put. It looked like one (the large orange butterfly koi) was trying to suck off some algae from a rock, but the other just seemed to be...gasping? Is that what’s going on? I live in New Jersey and it’s been 85-95° every day lately, which I believe makes the oxygen in the water deplete faster, but it’s a pretty big pond in my opinion.
Can most of the oxygen deplete that quickly? If that is the case, what kind of solutions should I look into? More plants in the water? Less time with the waterfall unplugged? If you don’t think that’s the issue, what do you think is going on? The catfish, baby koi and sunny never do this. It’s just the three big koi and it’s not every day. I did feed them twice today, so maybe the waterfall was unplugged too long (remember, each feeding session is 2-3 hrs of no waterfall).
I took several videos (one has my pale white hand in it for size reference and so you can see how close I could get to them) and uploaded them to Dropbox. The link will be at the end of this post, let me know if it doesn’t work. I’ll post some screenshots from the videos here. Hopefully you guys have an idea what’s going on and the solution isn’t going to cost a fortune!
