At Hydrosphere Water Gardens & Fisheries pond fish are our speciality. We quarantine all our new arrivals of koi and goldfish and inspect them before they are allowed to be sold. We only import koi from respected breeders that are regularly tested for KHV and SVC. We guarantee all our pond fish to be healthy and free from disease, so it’s safe to add them to your fish collection. Due to factors beyond our control once the fish leave our location (such as water quality, fish stress etc) we guarantee our fish for a period of 5 days from the date of purchase. We also recommend that all new fish (from us, or any other supplier) be quarantined before introducing them into you pond.

We have an excellent selection of koi all season long to suit every taste and budget. We import quality Japanese koi directly from the best breeders in Japan. All our Japanese koi are quarantined upon arrival, and are sure to be healthy when you are ready to add them to your pond. 

If you are new to keeping koi and aren’t ready to pay the higher price of Japanese koi, or just have a smaller budget to stick to, we also have some great domestic koi available imported from one of the premier koi farms in the United States. 

Butterfly are always popular with pond keepers. With their long tails and flowing fins, they make a great addition to ponds. We carry all sizes of domestic butterfly koi.

Goldfish make great pond fish for ponds of any size. However, if you have a small pond, goldfish are the best choice because they don’t grow nearly as big as koi. We always stock red and white Sarasa comets and Shubunkin goldfish in a range of sizes sizes. We also occasionally have Wakin goldfish available.
