Hanover Koi Farms LLC

We are one of the top breeders of Koi and Butterfly in the USA! Best Longfins anywhere worldwide As well no one has a better quarantine and treatment protocol.

Hanover Koi Farms is one of the top breeders of Koi and Butterfly Koi in the USA. No other breeders breed more varieties/breeds of Koi, and this includes the much sought after Butterfly/Longfin Koi. We go to great lengths to assure you get the healthiest, parasite free Koi as is possible. Each time we process Koi from the ponds we literally look at them under a microscope to identify any possible parasitic intruders, and treat them as needed. We then look at them once again under the scope to make sure the treatments did their job in irraticating any such parasites. Very few other retailers do this very critical step of treatment and quarantine. We have the largest selection of Koi and Butterfly Koi in the USA as well. Our fish far exceed that of all the other places that sell Koi for both health, and quality. The quality is VERY noticable and you will see the difference between what a quality fish looks like as compared to the low quality fish that most other places sell at comparable prices.
