Hopefully they're just hiding under the leaves for winter, I keep them in a small man-made pond. Pumpkin comes up sometimes, not often but I've seen her a couple times.
I really need more koi, I added 2 more fish sense... They were grey and orange.. pretty. My fish are still alive but my oldest fish pumpkin I'm scared ate them :oops:
I have a mix fish, koi mixed with goldfish. She is very pretty. I also have 2 other types of fish which I have no idea the breed. The longest living fish I had was a goldfish at 10 years old and he just died last year. He was so pretty.
