Some Previously Adopted Hybrid Koi Goldfish

Example Koi-Comet (goldfish) Hybrid

This is a typical hybrid between a koi and goldfish. This one shows a hybrid's typical distinctive trait which is the large hump behind the head. Not all hybrids have this hump, but most do.


- Hybrids are sterile and can't reproduce.
- The hybrids I have experienced grow to 12" including the tail, and some up to 15" long.
- They seem to be tougher than koi and can take the lower water quality like goldfish can.
- Not sure on their life span (goldfish is about 10, koi is 60+).
- They also do not seem to attack plants like koi do.

With qualities like these, I am surprised that they aren't a more popular pond fish, and breed for commercial sale. I have seen many backyard ponds in the 500 gallon size, and hybrids would be a great fish for those types of ponds. Another great application would be a water garden and lots of plants -- the hybrids get bigger than goldfish, but not huge like koi, and won't tear up the plants.

Some report that hybrids have small barbels, but the ones I have seen do NOT. But here is the problem - all of the fish I could easily identify as hybrids came from mixed ponds, and there might be hybrids with barbels that look like regular koi. Someday I plan to do an experiment where I mix one goldfish with one koi, and then catalog the results. When I do that, will post a link on this page.

Guinness Record For World's Longest Goldfish

The current record holder for the world's longest goldfish at the Guinness Records isn't actually a goldfish. It is a hybrid between goldfish and koi, as you can clearly see in the picture to the right. It is 18.7" long from overall including the tail fin.
