The fish, up close
Koi, also known as Nishikigoi, are a variety of common carp that have been selectively bred for their vibrant colours and patterns. They have a streamlined body shape, long flowing fins, and can display an array of colours including red, white, black, yellow, and blue. Koi are incredibly hardy fish and can live for several decades with proper care. They are prized for their beauty and are a popular choice for ornamental ponds and large aquariums.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
Koi are generally peaceful fish that can coexist with a variety of tankmates. They are social and active swimmers, often seen gliding gracefully through the water in groups. Koi can become quite tame and may even eat from their owner's hand with time and patience.
Tank planning
Maintaining good water quality is essential for the health of koi. They prefer water temperatures between 15-25°C and thrive in well-oxygenated environments. Regular water changes and filtration are crucial to keep their environment clean and free of toxins. Providing adequate space and hiding spots will help reduce stress and promote their well-being.
