How long have you been living near that pond? Koi's seem really rare to have where I am fun. Was it expensive to get a pet koi? 
It was more expensive to build his home and have the right environment for him. Now, it's perfect. 
Is there one one fish in your pond? I never got a chance to see a koi fish in person. Only on the internet. Why did you decide to get a koi fish? 
Yes, I only have the one. As you asked, yes they are expensive, and there are so many environmental and natural predators that could make it hard for the fish to survive. I think they are beautiful fish, hence my decision to get one. And they instill a form of peace.
That is pretty awesome. I thought about getting a fish myself but they are too expensive for me. And I have no room for it. What color is your koi fish. I am guessing Orange/White? By any chance did you decorate your pond?
