Is it bad all I can think out is workaholic koi fish episode. Where they want to have a fish fry with them I’m their honor. Lol, I know how much this hurt. We lost all our koi in a day due to a guy we hired to clean the pond before winter. He came too late in the day and instead of draining the water for cleaning, he lazily dumped in a ton of chemicals. Oxygen went, fish are gone. It was devastating, those fish had personalities and were so calming to have around.
Ah, that’s so sad! My grandmother went through a koi mishap a few years back. She had surgery and my grandfather was taking care of her and the house along with yard maintenance. Well, their koi pond is next to the pool. He got the chemicals mixed up for the koi/pool from just being exhausted. He realized about an hour later and was still able to save some koi by moving them to buckets but lost their largest ones that they’d had for years.
