Cardinals – aquarium fish that are almost gone
Cardinal (Latin Tanichthys alboneubes) is a beautiful, small and very popular aquarium fish that you probably know. But, you know, what are you …
Cardinal habitat in nature has changed significantly in recent years, and this has affected the number of fish. Wildlife has become parks, hotels and sanatoriums. This led to the fact that the cardinal disappeared, and since 1980, for twenty years, there has not been a single message about the population.
The species was even considered extinct in its homeland in China and Vietnam.
Fortunately, a small amount was found in isolated areas of Goundong Province, and on Hanyang Island in China, as well as in Quang Nin Province in Vietnam. But this species is still very rare, and is considered endangered in China.
The Chinese government is taking measures to restore the cardinal population in nature. All individuals of the cardinal, which are now sold – raised in captivity.

Cardinal fish: compatible with other breeds
Optimal conditions for the flocks of good-natured small cardinals – a separate aquarium. There they will be most comfortable.
It is very interesting to watch their quiet games, and to multiply and behave in a calm atmosphere, the cardinals will be clearly more active. Calm and funny fish cardinals are too peaceful.
They can be offended by representatives of aggressive breeds. Dangerous neighborhood with predators such as astronotus, piranha, barbus, angelfish, goldfish. It is necessary to take into account the lack of agility of the Cardinals.
Even quite peaceful inhabitants of the aquarium, the size and strength of which is greater than that of these fish, will be their serious competitors in the division of food and territory.
Lack of food or a comfortable place will affect the general state of health, the ability to reproduce, the appearance of the cardinals. If you still want to observe the diverse inhabitants in your glass pond, you can look at guppies, fiery tetras, danios, rhodostomusam, crescents, neons, honey gourami, corridors, glass perches or shrimps.
Cardinals are considered to be peaceful and non-aggressive aquarium dwellers, which are recommended to be kept in flocks of 6-8. They get along well with ternetii, red neon, rhodostomusami and danios. Basically, the cardinals are kept in the upper layer.
You should not have any difficulties with keeping aquarium fish. Prepare a small aquarium, based on the proportion of 30 liters of water per pack of up to 7 pieces.
Make it the water level centimeters 25.
Aquarium soil can be used in the form of river sand, which must be processed before being laid in the aquarium. It is also possible to use small pebbles as a substrate.
It is also recommended planting aquarium plants, but not very thick. As a rule, they put an elodea, a people, a hornpole or a vallisneria into an aquarium. The parameters of aquarium water in an aquarium with fish cardinals should be the following: hardness: 4-20, pH: 6.5-7.5, water temperature: 18-21 degrees.
The aquarium requires filtration and aeration of water, as well as weekly changes of up to 20%. Cardinals also like bright lighting, especially light is needed in the winter.
There is a cardinal live and dry food. Perfectly eats cyclops, bloodworm, dry daphnia.
In nature there is almost all the time small insects.
|Breeding cardinals who, being in the general aquarium, are constantly malnourished due to inactivity, require special conditions.|
Therefore, in the spring, 10-15 days before the intended breeding, males and females are deposited in separate containers. Otsadniki, where fish are constantly fed small live food, can be three-liter jars filled with fresh settled water, which is periodically aerated. The water temperature is maintained at 22-23 ° C.
The cardinals nest consists of two females and one male. In order to avoid any accidents, two nests are prepared for spawning.
The readiness of the fish is determined by the female, whose abdomen acquires a noticeable roundness.
Spawning for one or two nests can serve as a low aquarium from 10 liters of water. The bottom of the vessel is covered with a layer of well-washed coarse-grained river sand, about 1/4 of the capacity is taken away under small-leaved plants, such as perististolemum, golodniknik or nitella.

The Ludwigius planted in the ground, Indian fern, and hygrophil are quite suitable. It is preferable to make water for the spawning area from “old” and fresh (separated) water, mixing them in equal parts, but you can also use fresh water.
The water temperature is not lower than the one in which the fish were prepared for spawning. Its level is small – 20-25 cm.
The lighting is moderate.
The fishes placed in the spawning grounds immediately become lively, and the males begin their courtship ritual – make elegant turns around the females. When water temperature is up to 25 ° C, fish liveliness increases.
Spawning can last for two days. During this time, one female sweeps up to 30 eggs.
If you need to get a second after the first spawning, and they can be up to ten with 8-12 days breaks, the producers are again seated in different containers and heavily fed with live food. Stopping breeding, the fish are placed in a common aquarium with the usual feed and temperature regimes.
Incubation of caviar lasts from 30 to 50 hours depending on the temperature of the water, which should not be subject to significant fluctuations.
Cardinals’ larvae are so small that they are barely visible with the naked eye. The larval period, when these crumbs hang motionless on a particular substrate, lasts up to 2 days.
p> The fledged cardinal fry are fed without departing from table 2, but because of their small size, feeding with infusoria or other starting food is somewhat lengthened. The small size of cardinals, the peculiarity not to destroy their eggs and offspring, even in the larval stage, as if by nature itself predetermined their content in the aquarium separately from other fish. In the 15-20-liter capacity, you can create a miniature copy of the natural reservoir, observing all stages of life of these fish, without disturbing them with transplants to prepare for spawning and spawning.
The device of a specific aquarium for cardinals (it will also be a breeding ground for 3-4 nests of these fish) provides for the presence of sand and a small number of plants on the bottom. The only difference between such an aquarium and an ordinary breeding ground is that the water in it ages, acquiring an amber-yellow color, and therefore 1/5 of it should be replaced with fresh water every week.
Normally feeding, even with surrogate foods or dry feed, the fish, being in optimal temperature conditions for breeding, are occasionally ready for spawning without special training. This makes it possible to observe the “tournament battles” of the males and see their courtship for the females.
With hasty movements with flowing fins, males hover around females, periodically bouncing off to the side, rushing into the midst of plants, as if inviting them to follow them. When the efforts of the males bring success, the fish hide in the thickets of plants, where the spawning takes place.

Before the eyes go through all the stages of life of a miniature fairy underwater world. A hank of caviar lasts not 2-3 days, as during normal spawning, but about a month, since every day a female spawns only 2-3 eggs.
Rest after such spawning lasts about a week or more. After this, the normal life cycle begins.
The fry that have appeared in 3-4 days from the moment of spawning begin to feed, as usual, with small living “dust” or artificially grown culture of ciliates. Since, in contrast to the temporary spawning grounds, there are always a small number of ciliates and other aquatic organisms in a lived-in aquarium, feeding newborns in the first period of their life becomes easier – in one way or another, they find food.
If day by day the number of fry increases, then without adding starter feed is not enough.

True, there may be a slight increase in the number of ciliates directly in the aquarium, if you provide them with food. For this, a thin slice of carrot or a small piece (1 sq. Cm) of banana peel is suspended on a stainless wire in the uppermost layer of water.
Getting wet and decomposing slowly (if there is aged water in the aquarium, but you should be afraid that it will deteriorate), they are a good environment for bacteria, and those, in turn, will contribute to an increase in the number of ciliates. After the first portion of the feed for the ciliates is completely decomposed, it will disintegrate, you can hang a new one.
The first fry, attracted by the abundance of small food in a certain place, remain there until this food ceases to satisfy them. In place of the grown-up fry (they go in search of a larger feed) come more and more new generations in need of an initial feed.
You can continue feeding juvenile cardinals on any surrogate feed, not excluding dry feed. Growth rate of fry naturally slows down.
And yet the fish eventually reach good size and full development, which allows you to get offspring from them.

Cardinal (fish) – fish of the carp family, of the class Ray. The name got its due to the desire of easy money merchants, who hoped that it would be better sold for industrial purposes.
The Latin, classical specific name is more euphonic: “alba nubes”, which literally translates as “white clouds”. For the first time these fish were found in China.
In Guangdong, China, in 1930, the leader of a pioneering movement named Tang Meng Yo made the first entries about cardinals. In the description, it was stated that this fish survives well in water with a low temperature, and, as it turned out later, aquarium conditions for it are also not a bad place. Later it was sold under different names, and the “cardinal” was not the only one.
Chinese danios, false neon, magnificent minnow – such names are often found on the market.
The fast south Chinese rivers are the natural habitat of the cardinals. Keeping and breeding them is available only in aquarium conditions, since they are almost wiped out in the wild.
Since the 1980s, there has not been a single notification about the places of their population. In China, this species was temporarily considered extinct.
Miraculously, it turned out that a small school of fish was found in some Chinese and Vietnamese provinces. All fish sold today are bred.
