Overview
What to know before you buy.
Koi are ornamental varieties of carp, famous for their beauty, size, and longevity, often kept in outdoor ponds. They come in a vast array of colors and patterns, such as Kohaku, Sanke, and Showa. While peaceful, their massive size and waste production make them unsuitable for all but the largest indoor aquariums.

Care guide
Everything you need to keep Koi healthy in a South African setup.
Water parameters
Keep pH 7–8.5 and 15–25°C. Stable parameters matter more than chasing perfect numbers — acclimate new arrivals slowly.
Feeding
Koi is an omnivore. Feed a varied diet appropriate for freshwater fish — quality flakes, pellets, or frozen foods sized to the mouth.
Behaviour
Koi is generally peaceful. Observe during feeding and at lights-out for true temperament.
Tankmates
Pair with similarly sized peaceful tankmates in freshwater fish. Avoid fin-nippers or species that outgrow this fish.
Breeding
Breeding notes for Koi vary by line and water chemistry — ask your local shop about proven pairs in SA.
Settling this fish in?
Condition the tap water, seed the filter, test through the first weeks — most early losses trace back to one of those.
