Useful from YT!
Ian-qw1zb Okay so I'd like to be corrected on this if it's not true but can't find anything saying that they can handle water below 40°. I have one he's probably about 10 inches and I separated him from my koi when I finished my outdoor pond and put my koi outside. And it's because I can't find anything saying they can handle it when the water freezes over. As a matter of fact i have been told they can't handle our New York Winters.. their comfort range is 55 to 72 they go dormant below 55 (the same as koi) and to my understanding they go belly up below 40 degrees Fahrenheit. They're from the Yangtze River and I don't believe the Yangtze River ever freezes it stays cold year round but. But like I said I can't find nothing saying they can.
Jack-gh3vs I can give you my first hand experience keeping one in northern Colorado. I got about a 4 inch high fin in late march of 2023 and put him into my koi pond. He’s fed solely on algae within the pond and is growing well. He overwintered perfectly, just as the koi and goldfish do. The ice on the pond got to about 5 inches thick. I do have a waterfall and a couple of air stones running on the pond just to give you an idea of my setup. The pond is 3 foot deep in the deepest part, and probably about 1,000 gallons
Ian-qw1zb thank you that helps first-hand experience is what I was looking for. And I bet the algae will make it grow well.. they seem to be a picky eater preferring to graze and never to compete.. super docile fish. So then there's the only other thing is can they handle 90 degrees +excessively in a 3-foot pond mine is roughly 1400 gallons planning on building one adjacent to it with a connecting stream next year..
Fish-Story Wonderful input, thank you so much! My two thoughts connected to this are that this pond is on the small and shallow end and there is a risk that it'd freeze all the way to the bottom at some time (cold winter, cold spell), which would kill all fish. And the other thought is trivial, I am sure you know - the pond needs to have a breather hole open all the time it is iced over for gas exchange.
Fish-Story A couple of visitors of ours were from Massachusetts and maybe NY or NJ and had had High Fins in their koi ponds for decade+. I am sure their ponds freeze over. But no personal 1sthand experience of mine. You did make me doubt!
I am so grateful for the Colorado Jack's input.
Fish-Story As I reported before and also in this video, our prior attempts with High Fins led to their demise at temps over 85F, despite superb aeration. I believe. Can't prove it but the two tries with multiple fish each time seemed quite consistent to me.
