"Today's dinner is goldfish."
Translation:오늘 저녁은 금붕어 입니다.
Apparently they're edible, though I can't imagine they're worth the effort. Perhaps it works for owls...
Apparently, you are correct. Although they aren't palatable to humans as water has more taste than their meat. I'm saying this out of experience.
It's a common dish in my country but I guess the word "goldfish" itself kills my childhood cause I imagine the fairy odd parents being a dish.
