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.
Key traits
Care guide
Keeping Koi healthy in a South African setup.
Tank setup
Size the aquarium to Koi's adult size and activity level. Provide hiding spots and stable, well-filtered water; it suits a community 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
Omnivore. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Peaceful. Keep it in a group for natural behaviour.
Tankmates
Choose tankmates of similar size and temperament with the same water needs. Avoid fin-nippers and anything large enough to eat it.
Breeding
Breeding success with Koi depends on the line and water chemistry; ask your shop about proven pairs.
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.
