To date, aquarium fish, or rather, their varieties are quite numerous and varied. But always the most important among them are considered, in fact, the legendary goldfish.
Interesting golden inhabitants of the underwater world are far from simple creatures. And in order to ensure proper care, to maximize their life expectancy and prevent diseases (do you wonder how many years such fish live?), Finally, in order to ensure their reproduction, many nuances should be taken into account.
Typically, the length of goldfish comes to 30-35 cm. However, in aquarium conditions, the indicators are much more modest: you rarely find fish over 15 cm.
The body of these aquarium fish is slightly elongated in length, has the shape of an ellipse, flattened from the sides.
As for the fins, the dorsal is very long, starting in the middle of the body. The anal fin is relatively short (it is related to the tail). Usually these creatures have red, slightly reddish or completely yellowish fins. The belly, as a rule, has a yellowish tint, the sides are golden, and the back is red-golden.
However, there are various types of these aquarium dwellers that may have pale pink, red, black, white and even spotted color.
Goldfish require carefully selected aquarium conditions. First of all, you need to understand that keeping one fish requires at least 50 liters of water. However, as the number of fish in an aquarium increases, an increase in their population density is allowed.
At the bottom of the aquarium should be a coarse-grained soil, because the fish love to rummage in it. Pebbles need to pick rounded, which do not have sharp edges. The content also implies plants, only it is better to let them not with small leaves, since the dirt lifted from the ground will settle on such leaves. Floating plants will also be useful. they can be used for feeding.
Now let’s talk about the parameters of water: its temperature varies from 16 to 24 degrees (lower temperature is needed in winter, as the summer period approaches, it is necessary to gradually increase the temperature of the water); rigidity. at the level of 8-18 degrees, the acidity is needed around 7.
In general, water should be given maximum attention (after all, its quality affects even the life expectancy of the fish themselves, i.e. it depends on how long the fish in question live). It must be rich in oxygen, must be clean. Every day should be replaced about a tenth of the water. Without a filter can not do. Inadequate water quality provokes disease.
Speaking of longevity. How long do these funny inhabitants of the water live? No one can name the exact period how long they live, but there is a case when a goldfish has lived to 34 years without a single disease. How long do they usually live? From 3 to 10 years. The length of life of these creatures depends on what their content.
Now consider compatibility. Here it is necessary to take into account the variety of goldfish, because not all species have complete compatibility with other fish. In addition, even the compatibility of fish with each other is not always observed. Check compatibility with one or another fish is still not worth it. In any case, peaceful and calm neighbors, not too large, will ensure almost absolute compatibility.
How to feed?
To feed the fish in question is very difficult, especially for beginning aquarists. Why? Goldfish are very voracious creatures that almost constantly ask for food. You can say this: how many live, eat so much. However, feeding them too often is strictly forbidden because they develop diseases.
The recommended feeding regimen is once or twice a day (otherwise diseases are observed). Portions should be made small: let the fish eat everything for about seven minutes. But what can you feed?
The answer to this question is very simple: you can feed almost everyone, because goldfish are omnivorous creatures. Because of this, the diversity of their food suggests the presence of:
- live food;
- specialized dry food;
- plant foods (i.e. need plants).
It is advisable to buy live food frozen (this will exclude the likelihood that the fish will have the disease), then to thaw it and feed them to the fish. Dry it is recommended to pre-soak in a small saucer with aquarium water. Plants before you start to feed the fish should be scalded (this will also prevent disease) and grind. It is noteworthy that adults can eat the plants even if they are not crushed.
What plants can be? It should be particularly highlighted salad. The leaves of this plant are very fond of fish. Plants can be perfectly supplemented with fruit.
In general, it should be noted that the issue of nutrition of goldfish should be approached very responsibly. It is very important to feed these aquarium inhabitants properly and in a timely manner. If all requirements are met, fully-developing adult fish will easily endure a two-week hunger strike (in case of leaving for a vacation or a business trip).
In addition, there is the possibility of leaving the fish for a longer period if there is such a need. Then they can be left in the aquarium a little more of the horn.
We also point out that a number of experts recommend supplementing the ration of goldfish with cereal porridge. Such porridges should be cooked in water without salt. It is desirable that they were crumbly.
Having thoroughly studied the basic rules that ensure the proper maintenance of goldfish, one should also consider the issue of reproduction.
So, if you wish to reproduce these aquarium dwellers should stock up on a spawning aquarium. Such an aquarium should be about 80-100 cm in length (different types of fish require to some extent different care when breeding). Spawning need to close on top. It is important that it be planted with small-leaf bushes.
Water must be fresh, saturated with oxygen. Its performance is generally similar to those established in an ordinary aquarium.
In early spring, the fish begin mating games. It is recommended to plant them for 2-3 weeks, providing a good feeding. Then, two or three males and a female should be selected for spawning.
In goldfish, spawning usually occurs in the morning and lasts until the middle of the day. How is everything going? The female swims among the plants (or directly above them), where she spawns. This calf is then fertilized by the male.
After that, the fish should be removed from the spawn (remember about compatibility: not only different species can not live together, but also individuals of different ages), and the eggs should be provided with the right care. This implies, above all, the protection of the eggs from sudden fluctuations in temperature, on which the life expectancy of future fish depends. How long do the eggs live? After two days the fry already appear, and on the 5th day they swim boldly.
These are the key features relating to goldfish. Recall: you need to take into account also that these aquarium inhabitants are very diverse, their different types have different compatibility with other fish, but in any case they are voracious. In addition, often goldfish affect certain diseases. By virtue of all the above, it is rather difficult to ensure the content of these creatures. But competent care greatly facilitates the situation. In addition, we noted that the correct conditions of detention affect the lifespan of the fish. And how much do these fish live with you?
