My childhood friend's cousin is planning to do a major renovation to his semi outdoor pond. He asked me if I could take care of his koi (11 in total) while renovation is ongoing. It's gonna be lots of extra bioload added to my existing 8000 gallon system and serious precautionary actions are needed, but I eventually told him I would take them in. As a token of gratitude, he said I could keep 2 of his koi. I'd love to hear your opinions, feel free to judge them. Hopefully I could learn a thing or two from this
I was told #1 and #2 were bought in June 2023, #3-6 in October 2023, #7-11 in January 2024, all were bought as Tosai around 6-7". As of January 2025, the smallest is #7 at 13.5", biggest is #4 at 18.5". The scale in the pictures is in centimeter mind you.
Someone please enlighten me about their IDs. My guess #1 is kohaku, #2 doitsu kogane ochiba, #3-5 karashi koyo, #6 kogane ochiba, #7 sanke, #8-10 showa, #11 shiro utsuri but I'm not so sure. He doesn't remember either, he said his wife picked them because they're cute. That's what she said I guess![]()
