I have a pond at home with a pet koi named spot. He's red with a large black spot.
That sounds cool and I'm sure provides a nice aesthetic. Are there any distinctive features of the koi fish?
They can be distinguished by their color, patterns, and scales.
That's cool, I think they are traditionally found or popularized in Japan. Do you only have one koi fish?
Correct, because they were first domesticated in East Asia and used for food. Yes, I only have one.
I didn't know they were originally used for food. They look so cool it seems like it would be hard to only own one. Are they tedious or difficult to take care of?
No, they are easy to take care of because they can adapt easily to a variety of climates.
