I stumbled on this video this morning - very pretty water feature build from June 2020 - but I see they've tagged the video #koi and think "oh please no... NOT a koi pond!"
They do indeed introduce a number of koi into the water feature - a "4 in 1 Pond filtering system" (basically a fountain with a basket on it), a few floating hyacinths, and he says in the comments they "waited a week and tested the water" when someone expresses concern that they put fish into an un-cycled pond... zero hope for these pretty fish.
So I poke around a bit on their channel and, shocker - here's the video they posted a few months later:
Essentially all their fish have ulcers by this point. "How did this happen" they ask? They attribute it to "we didn't quarantine new fish!" (They added MORE fish? It's hard to count in the first video but there had to be at least 10-12 fish originally.) So he then goes into a demonstration on how to give a salt bath to fish with ulcers, how to do a scrape and how to treat ulcers with medication... he mentions water quality being critical to fish health, but doesn't seem to apply it to their pond situation.
I'm not picking on this particular YouTuber - this is just an example of what I see ALL THE TIME on the internet. People watch these videos, fall in love with the idea, and make the same mistakes. It's sad for the fish but it's also sad for people who get into ponding this way and will become very discouraged when they constantly have sickly fish.
Thanks for coming to my TedTalk.
P.S. Oh look - he built and EVEN SMALLER POND and put koi in that one, too! And shares the importance of adding salt to your pond... sigh.
