It's so weird. I know Japanese and I know chatGPT mostly confidently wrong. But still I wanted to believe it and give it the benefit of the doubt. I was wondering if fish had another pronounciation in addition to sakana.
うお is indeed a valid reading of 魚, just not in 青い魚. But 飛び魚 (flying fish) for example is とびうお. btw, the bit chatgpt spit out about い in 青い meaning to be is just totally wrong
