Keeping koi carp in a pond
Japanese koi carp can live anywhere from 25 to 35 years in captivity.
Some breeds of koi carp that are genetically closer to their wild ancestor are known to reach lengths of up to 130 centimeters. However, they are typically only 90 to 100 centimeters long.
Considering the aforementioned, it makes sense that keeping koi carp in a pond as opposed to an aquarium is preferable.
One can construct a pond with both soft waterproofing and a concrete base. For the latter, synthetic rubber (EPDM) is utilized. It allows you to design reservoirs in any size or shape. Using fleece, a specific backing, is also required if there are jagged stones in the ground. This will shield the EPDM film from harm. Although it costs more, a concrete-base pond is the most long-lasting. You can increase the water volume of a concrete pond by creating steep vertical banks, which conserves space. This is a forum for maintaining fish in ponds.
Furthermore, we would like to draw your attention to the products of the well-known Dennerle brand, which are designed for ponds; you can read more about them here. You can get the aforementioned supplies, tools, and other practical items for aquarists from the reputable FF online retailer Aqua Logo Shop. We advise against it!

Minimum pond dimensions that are advised:
– 8 tons in volume (3 x 2.46 x 1.23 meters).
Keep in mind that these brocade koi require a large pond because they are highly active fish that must swim. Since everything depends on how many koi carp you want to settle in the pond, there is naturally no precise data on what the pond’s volume and depth should be.
Suggestions for where to put the pond are: somewhere near the house (so you can watch the koi regardless of the weather) but in a peaceful, quiet area of the garden (as far away as possible from noisy places, like a highway). The pond should be lit by the sun’s rays the entire day.
Water from nearby areas should not enter the pond when snow or rain melts. To achieve this, either the pond is raised or a storm drain is built around it.
It’s crucial to install a strong biological and mechanical two-stage filtration system in the pond. In addition to ensuring that fish waste products and nitrogen cycle products—ammonia, nitrite, and nitrate—are effectively removed from the water, it should also preserve a regular gas regime.
It is theoretically impossible to use the filtration system in a large flow-through pond that has aquatic plants in it. However, it’s possible that koi will begin to eat underwater vegetation or scavenge the ground for food. Thus, the best ways to set up a filtration system are to construct a second regeneration pond with aquatic plants or a bioplateau, which is a small pond or stream that is entirely covered in pebbles and has aquatic plants planted in it so that water can circulate out of the pond.
The volume of the pond determines the majority of factors that impact biological balance, including temperature and dissolved oxygen content. Therefore, it is easier to maintain biological balance in larger ponds.
Keeping koi carp in an aquarium
We believe it is unnecessary to focus on the fact that a koi carp aquarium needs to be big—500 liters or more is preferable—in order to accommodate the fish. Of course, a beginner aquarist might find these figures shocking, but for experts and enthusiasts, they don’t seem that high. All of us have seen aquariums holding African or American cichlids that are 1000 liters or larger. And these are now commonplace items rather than a luxury.
Water parameters for keeping koi carp: general hardness 4–10 GH, carbonate hardness 1–7 KH, nitrogen compounds should be at zero: NH4 0, NO2 0, NO3 is acceptable up to 40. Every conscientious aquarist should always have a set of drop tests on hand, at least for nitrate and phosphate. Fortunately, they have become inexpensive now, there are no problems with their assortment and acquisition. For example, we can recommend you with a clear conscience the cool drip ones that we have tested on ourselves UHE tests, but they are sold only online. In the shops of your city – offline, you can find inexpensive Vladox tests. Keep an eye on nitrogen compounds, keep them in check and everything will be fine for you and your pets.
Koi prefer water that is between 15 and 30 degrees Celsius, while carp can withstand variations in temperature between 2 and 35 degrees Celsius. However, their immune system "turns off" at the same moment. Neutral pH ranges from 7.0 to 7.5 are ideal. The ideal O2 concentration in the water is 4-5 mg/l, but fish can survive with as little as 0.5 mg/l.
Maintaining adequate filtration is crucial for keeping koi carp in aquariums. This can be accomplished by using phytofiltration in addition to installing two filters that focus on mechanics and biology. It is possible to use medications, such as Tetra EasyBalance, that remove nitrogenous materials and phosphates.
Fine or medium-sized sand should make up the aquarium’s floor. The aquarium itself is furnished to your preference, but don’t go overboard because the fish will always dig up and rearrange the ornamentation as they see fit.
Based on the information provided, we can deduce that while koi carp are incredibly gorgeous and widely available in pet stores, they are definitely not suitable for novice fishers. This fish is intended for an experienced aquarist, ideally with a home in the village.
Speaking of which, novices in aquaristics frequently mistake koi kapov for goldfish because of certain similarities between the two species. This is untrue, though, as they only have one family—carp. The genus, however, is distinct. goldfish, genus Carassius (crucian carp), and koi, genus Cyprinus (carp).
Types of koi carp
There are many different colors of koi carp, but the primary ones are white, black, red, yellow, blue, and cream. More than eighty rocks are present. They are separated into 16 groups for convenience, each of which is connected by one or more shared traits. Gosanke, which includes the kohaku, taisho sanshoku, and showa sanshoku, is the most widely recognized breed of koi.
Kohaku is a type of white carp that has distinct red or reddish-orange markings on its back.
Sanke, also known as Taisho sanshoku, is a white carp with red and black spots. christened in Emperor Taisho’s honor.
Carp with red and white spots on a black body, known as showa sanshoku. christened in Emperor Showa’s honor.
Tancho: Koi with a red spot on their head, regardless of color. There are several names for "tantcho," including tantcho shyowa, tantcho sankei, and tantcho goshiki.
Koi known as asagi (asagi) have red (red-orange) scales on the sides and blue scales on the back.
Shusui (shusui) – A variant of Asaga that is somewhat larger; the carp has blue on the back and red (red-orange) spots on the sides.
Bekko is a black-spotted white, red, or yellow carp.
Black koi with red, yellow, or white markings are known as utsurimono.
Goshiki are primarily black koi with patterns in red, white, brown, and blue.
The most popular colors for ogon, or solid koi, are red, orange, grey, yellow, and light yellow.
Koi with shimmering silver (kinrin) or golden (ginrin) scales are known as kinginrin (Kinrin/ginrin).
Varieties of koi that do not fit into any of the aforementioned categories are known as kawarimono or kawarigoi.
Doitsu-goi: German carp with multiple rows of scales, similar to mirror carp, or without scales altogether.
Koromo are white koi with neat red and black dots covering them.
Golden-silver hues blended with a metallic sheen characterize Hikari-moyomono-koi.
GhostKoi, or Ghost Koi, are a "hybrid" breed of wild carp and ogon. lacks nishikigoi status.
Dragon carp, also known as butterfly koi, or veil koi, are the longest-bodied species of koi on the list. lacks nishikigoi status.
Feeding koi carp
Like any aquarium fish, koi require proper, balanced, and varied feeding. The secret to successful fish keeping is to follow this basic guideline. We would like to bring the Tetra product line for the pond to the readers’ attention. Excellent, tested feeds!
It should be mentioned that when purchasing any dry food, you should be aware of the manufacture and expiration dates, avoid purchasing food by weight, and store it in a closed environment to prevent the growth of harmful flora.
Breeding koi carp
We will state up front that doing this at home is very difficult. You’ll need a big aquarium for this.
Before they reach puberty, it is impossible to determine the floor of carp koi. When a fish reaches spawning age, or roughly 23 cm in length, sexual dimorphism manifests. However, it can occasionally be challenging for adults to determine the floor.
The primary indicators of sex differences in carp koi. Females are heavier than the body, which is connected to the requirement for nutrients for the proper functioning of the eggs. Males have more pronounced and aesthetically larger relative body fins. Similar to goldfish, during the mating season, koi males emerge on the tuberculi gill covers.
When the temperature rises, which occurs in late spring or early summer, carp in the pond will spawn. 20 C is the optimal temperature for spawning.
You can witness mass spawning if the pond has a large number of koi. Although this type of spawning produces healthy progeny, many aquarists steer clear of it because the fry typically have a much paler color than their parents. Breeders typically choose two producers and place them in different spawning ponds. The spawning pond doesn’t have to be fixed; it can be a kid’s rubber pool or another type of reservoir. Frequent water changes are implemented during the spawning period, and the fish are fed an abundance of live, high-protein food.
After spawning, the producers are eliminated in order to produce more offspring because the parents can consume the eggs and fry. For fry to survive in a pond, there must be adequate aeration. After a week, the eggs hatch into fry, which cling to the pond’s edges and stay there for two to three days. The koi carp fry then start to swim freely. The young must begin feeding at this point.
This brings the article to a close, and we will state here that these precious fish are passed down as family heirlooms and property in Japan. The most expensive koi carp was once sold for 50,000 US dollars, but you can get a fry for 50 rubles.
These and a variety of other fish are always available at the physical supermarkets Aqua Logo and the internet retailer Aqua-Shop. Live goods delivery is available in Moscow and the surrounding areas.
Beyond simply being gorgeous accents to any pond, koi carps add a serene and beautiful element that can completely change your outdoor area. Both casual observers and fish enthusiasts like them for their graceful movements and vivid colors. Whether you’re an experienced fish keeper or a beginner, koi provide an engaging experience that’s difficult to top.
Although it takes some time and effort to maintain koi, the benefits are priceless. These fish can grow and thrive with the right care, giving you years of enjoyment. Maintaining a clean, healthy environment, feeding your koi appropriately, and maintaining a regular pond are all essential to their happiness and vitality.
In the end, koi carps are living works of art that bring elegance and serenity to any environment. They are more than just fish. Giving them the attention they require will guarantee their wellbeing and deepen your respect for these amazing animals. Koi are a great addition to any aquatic setup, whether you’re just enjoying their presence or appreciating their colors.
Beyond being merely decorative fish, carp koi are colorful, durable friends that can enhance the beauty and tranquility of any garden pond. These fish, which are native to Japan, have many different hues and patterns, each with an own appeal.
