Assorted Koi

Koi are the ornamental colour forms of the common carp (Cyprinus carpio), selectively bred in Japan over generations and now kept by hobbyists worldwide. Our assorted koi arrive in a mix of whatever the shipment brings, so you may see white and red, black and orange, metallic single colours or patchwork patterns, with either regular or reduced scaling. They are calm, curious and quick to learn who feeds them, which is a large part of their appeal.

Aquarium care

• Assorted koi are sold small, but they grow into big, deep-bodied fish and need a large volume of well-filtered water as adults.
• They are omnivores and take sinking or floating prepared foods readily.
• Koi are social and settle better in a group than kept singly.
• They root around in substrate and will uproot or graze soft plants.
• Strong biological filtration and consistent water changes matter more than heating; they tolerate cool water well.
• A secure cover or adequate freeboard helps, as startled koi can jump.

Assorted koi suit a keeper who has, or is building, a large system and wants long-lived fish with real personality. They are best kept with other koi or similarly large, peaceful coldwater fish rather than small community species that could be swallowed. Common carp is invasive in many places it has been introduced, so never release koi into a lake, river, irrigation canal, storm drain or any natural waterway; contact us about rehoming if your circumstances change.
