Scientific name: Cyprinus rubrofuscus (variedades domésticas)
Long-lived and large fish that require spacious ponds and good water quality year-round.
How this species lives in its natural environment, with the waters, shelters and resources it needs.
The koi carp is a symbol of aquatic gardening and Japanese culture, but requires serious and well-designed facilities.
They require deep, well-filtered and oxygenated ponds, with shaded areas and refuges.
They are social, form active groups, and spend much of their time filtering the bottom in search of food.
Their contrasting colors (red, white, black, yellow…) make them very visible, which increases their vulnerability to predators outdoors.
They are not threatened as such, but can hybridize and compete with wild carp if released.
Striking details about this species that help better understand its biology and role in aquatic ecosystems.
Summary of the most critical points if this species is kept in aquariums, ponds or specialized facilities.
In captivity they need large-volume ponds, powerful filtration, and constant oxygenation.
They suffer in small spaces, with poor filtration or without protection against intense frosts.
Handling must be very careful, using appropriate nets and avoiding injuries to fins and scales.
General information aimed at professional facilities, public aquariums and educational projects. It does not intend to promote capture or impulsive keeping of aquatic fauna.
Their maintenance is appropriate for botanical gardens, parks, and individuals with adequate facilities.
Feeding should be adjusted to water temperature and season of the year.
It is advisable to partially cover the pond and offer refuges against predators.
They should never be released into rivers or reservoirs, due to their potential impact on native ecosystems.
Many aquatic species suffer from massive captures, uncontrolled trade and irresponsible releases. The priority should always be to protect rivers, lakes and seas, reduce pollution and consume seafood responsibly.
