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.

Tanichthys albonubes, or simply cardinal – an ideal fish for those who are just starting their acquaintance with aquarist. These small and mobile creatures are not only beautiful, but also very simple in maintenance and care.

But first things first.

The rapid streams of mountain streams in southeastern China are considered to be the historical homeland of these carps.

From there, the cardinal was brought to Canada (1935), then came to the United States, and after that to Europe, and more precisely to Germany (1938).

It should be noted that from 1980 to the present, the cardinals have been considered an extinct species in China. This is due to the influence of man on wildlife and its transformation into parks, hotels, sanatoriums and so on.

A small number of fish survived in the provinces of Goundong (China) and Quang Nin (Vietnam), but it is negligible. The Chinese government is taking measures to preserve and restore the population.

And all the fish that go on sale and which we see in pet stores, are raised in captivity.

Tanichthys albonubes should preferably be settled in an aquarium with a large flock of 15 or more individuals (and there should be 2-3 males in the flock, not more). If the cardinals in the home pond will be a bit, then they become fearful, most of the time hiding and losing the brightness of the color.

And so it is very peaceful and friendly creatures that do not conflict with each other, do not touch their fry, and treat representatives of other species very well.

About how to choose the right fish in the aquarium will tell our article.

We advise you to read the article Unpretentious aquarium fish.

Small neighbors, similar in temperament, will become good neighbors for them: a galaxy, a guppy, a zebrafish microassembly, etc.

Big, aggressive fish for which the cardinal will easily become food are categorically inappropriate. The neighborhood with goldfish is also not very good – they can eat.

It is also better not to keep along with catfish, gourami, laliusi and similar slow-moving calm fish, in which the cardinals will divert food from under their noses.

Aquarium better to choose an oblong shape. It will be enough and a small 15-liter for 5-7 fish. But the ideal is still a 40 liter spacious container.

The water level should not be below 20-25 cm.

Water. Cardinals do not like warm water.

In such conditions, their coloring fades and their life expectancy decreases. Also, there should be no sharp temperature changes, otherwise the fish will get a fungus.

The optimal parameters of water is considered to be the temperature of 18-22 degrees, the hardness of 4-20 °, pH 6.5-7.5.

Filtration and aeration very desirable. Every 1-2 weeks is required to replace 30 percent of the volume of water.

Lighting Fish need bright, so you need additional lighting.

Priming better to choose the dark. Suitable as sand and small pebbles.

Plants. Despite the fact that the cardinals prefer dense vegetation, the algae must be placed so that the light can reach the bottom, and there is a place for swimming.

Fern, myriophyllum, Ludwigia, Elodaea, Limnophila, Wallisneria and other small-leaved varieties are well suited. On the surface, you can arrange duckweed or riccia.

Decor. For decoration, you can install snags and stones.

  1. In Asia, cardinals are sometimes kept as pond fish. They are not only beautiful, but also help in the fight against mosquitoes.
  2. These carp are able to withstand temperature drops from 14 to 30 degrees.
  3. The name Cardinal is a commercial move. The merchants gave it to these fish so that the goods sold better. Such a name was often found in German books on aquarism of the time, from which it got into Russian and took root.
  4. In China and England, fish are called minnows, mountains of white clouds, or Guangdong minnows. They are so named because of their habitat. Cardinals can be found in fast and cool water flows on Baiyunshan Mountain, which is also known as White Mountain Clouds.

As we can see, it’s really easy to care for cardinals. They are loyal both to the volume of the dwelling, and to the parameters of the water, and to the stern.

The only thing that is important is to maintain the purity of the water. And so these fish will delight the owner not only at home, but even in a mini-aquarium in the office on the desktop.

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.
