How many fish can your water hold?

Pick your water, choose fish and sizes from the shop, and watch them swim in it. When it looks right, add the whole plan to your cart.

Your fish
2,000 gallons

    A conservative starting point from common hobby guidance: about 250 gallons per koi, 50 per pond goldfish and 20 per fancy goldfish in a pond. In aquariums, 20 gallons for the first fancy goldfish plus 10 for each more, or 40 gallons for each comet or shubunkin. Koi are planned at adult size. Good filtration and regular water changes matter more than any single number. 1 cubic foot holds about 7.5 gallons. Fish are counted in the same packs the shop sells, at shop prices; shipping is a flat $72 per box.

    Japanese koi varieties you'll meet

    Our koi mixes draw from these classic Japanese varieties. Here's how to tell them apart in your pond. Touch the water to say hello.

    Questions

    Can I choose an exact fish?

    Not yet. Most lots are assorted and picked at the farm, so the photos show the kind of fish you'll get rather than the exact one. Lines without the Assorted tag, such as Yamabuki Ogon or Redcap Oranda, are one variety.

    How many fish are in a pack?

    Exactly the number listed on the pack, from 1 to 6 depending on size. We never count on extras. Every box is packed well under the farm's limit, so each fish has room and clean water for the trip.

    Can koi and fancy goldfish live together?

    Koi and slim pond goldfish like comets share ponds well. Fancy goldfish such as Orandas, Ranchu and Bubble Eyes are slower swimmers and do best in an aquarium or a calm pond of their own.

    What size pond or tank do I need?

    Koi grow large and need a pond, ideally 1,000 gallons or more and at least 3 feet deep. Fancy goldfish do well in an aquarium with about 20 gallons for the first fish and 10 more for each one after.

    Do you ship everywhere?

    We ship within the US by UPS Next Day Air, Monday to Wednesday only, so fish never wait in a UPS hub over a weekend. In very hot or cold weather we may hold an order a few days so the fish travel safely, and we'll email you if we do.
