Fish Cardinal male and female

The female lays several eggs every day. Calf and fry parents usually do not eat. When floating fry appear, the producers are transferred to another aquarium, and in the first one they begin to feed the fry.

Food for the start – rotifers, cyclops nauplii, egg yolk or simply triturated dry food.

Feeding aquarium cardinals must be correct: balanced, diverse. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses.

Article “How and how much to feed aquarium fish” talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.

In this article, we note the most important thing – feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.

Popular and popular feed for fish, of course, are dry food. For example, hourly and everywhere can be found on the aquarium shelves of food company “Tetra” – the leader of the Russian market, in fact, the range of feeds of this company is striking. In the “gastronomic arsenal” of Tetra are included as individual feeds for a certain type of fish: for goldfish, for cichlids, for loricarids, guppies, labyrinths, arovan, discus, etc.

Also, Tetra has developed specialized foods, for example, for enhancing color, fortified or for feeding fry. Detailed information on all Tetra feeds, you can find on the official website of the company – here.

It should be noted that when buying any dry food, you should pay attention to the date of its production and shelf life, try not to buy food by weight, and also keep the food in a closed state – this will help avoid the development of pathogenic flora in it.

Thanks to its compact size, even in a small aquarium, you can make a flock of naughty and mobile fish. The cardinals are adapted to the gregarious way of life. Aquarists say that their behavior is very interesting to observe.

The great advantage for keeping fish in domestic aquariums is their peace-loving nature. Ideal neighbors for cardinals:

  • Guppy;
  • Danio;
  • Ternetia;
  • Red neons;
  • Rodostomusy and others

But do not forget that overcrowding aquarium will have a bad effect on the content. So, for a small group of 6-8 fish should be at least 15-20 liters of water. Designers are often used in the premises of low, long aquariums.

It is very beautiful and fits well into any interior. Cardinals have enough fish in water for 25 centimeters, so in China they inhabit shallow rivers. To aquarium fish feel great, you need to take care of the correct, close to the natural range,

In the aquarium must have:

  • Ground;
  • Plants;
  • Shelters;
  • Some pebbles;
  • Compressor for aeration;
  • Purification systems.

Soil is best used

vat sterilized river sand. If you can’t find it, you can use smooth small pebbles lined with a small layer on the bottom of the aquarium.

Plants that are actively growing need to be periodically cleaned, since for a freedom-loving fish, limiting space is the right way to the blues. It is better to place the algae near the back wall, leaving the cardinals a place to frolic, and you can easily watch their fun.

Water requirements:

  • The optimum temperature is 20 degrees;
  • Acidity from 6.6 to 7.6pH;
  • Stiffness from 4 to 20 degrees;
  • Frequent change ¼ of the water.

The content of the cardinals is not difficult. But, if you want to observe in your aquatic world adorable individuals who will look great and behave very lively, you will have to carefully monitor their diet.

Cardinals from the entire feed prefer a more natural for their natural habitat – live food. It can be purchased at pet stores.

In this case, aquarium fish tolerate dry food well, if you suddenly have to leave and leave the care of the fish to a friend.

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.

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.


Cardinal – a unique aquarium fish. The fact is that the cardinal has a very narrow habitat. His homelands are fast mountain streams in South China.

Since the 30s of the last century, the fish began to enjoy a certain popularity among fans of exotic aquarium inhabitants.

Fish are distinguished by absolute harmlessness, so that they can coexist with almost all aquarium inhabitants. It is necessary, however, to take into account that individual fish can harm the cardinals, so the neighbors should be chosen carefully. Often, aquarium cardinals are found together with freshwater shrimp.

But absolutely any kind of peaceful fish will be good neighbors: it can be neons, guppies, tetras, pecilia, and many, many others.

The content of cardinals in a large aquarium, which is rather densely planted with various aquatic plants with small leaves, is recommended. It is important that the fish have enough free space for swimming at the front glass of the aquarium.

Aquarium capacity sufficient for cardinals is 30 liters. The aquarium should be oblong (at least 60 cm long), so it’s not long to think about the shape.

It is recommended to close the aquarium cover. At the bottom of the aquarium, you can sprinkle small pebbles.

Considered aquarium fish is very demanding of cleanliness. For this reason, it is necessary to ensure a one-third daily water refreshment.

In addition, you need to place the aquarium in a place that has sufficient lighting. Water should have a temperature in the range of 17-24 degrees, while its acidity should be 6.2-8.2, and the hardness – 4-20 degrees.

When feeding, cardinals are good to live food, combined and dry. Feed should be about 3-4 times a day.
