Danio pink: content, compatibility, breeding, photo-video review
This article depicts and describes the pink, artificial breed danio rerio! True danios pink looks like this:
Order, family: Carp.
Comfortable water temperature: 21-25 ° C
Ph: ph 6.5–7.5, water hardness: 5-15 °.
Aggressiveness: not aggressive.
Compatibility Danio Pink: compatible with all “peaceful fish”: danios, terence, minor, tetra, scalar, soma, etc.
Useful tips: In my opinion the most beautiful fish of the kind “danok.” Look great flock, on a dark (blue) background of the aquarium film. Fishes quick and gregarious.
They can coexist with many species of fish, even with fish of medium and increased aggression: scalar, goura and even with small cichlids.
In order that the pink color of the fish was juicy, I recommend to buy specialized food (for example, Tetra-color).
Danio pink lives in the slowly flowing waters of Southeast Asia.
A small fish with a body length of up to 4.5 cm. The body is elongated, flattened laterally.
Body of fish beautiful pink, along which alternate white stripes pass. Fins transparent, colorless.
Fish are kept in the aquarium flock (from 6 copies). Danio pink contain in general aquarium with a length of 60 cm and a volume of 20 liters. The decorations of the aquarium can act – thickets and floating plants, stones, snags.
Fishes also need free space for swimming.
Comfortable water parameters: temperature 21-25 ° С, dh 5-15 °, ph 6.5–7.5, regular weekly water changes (1/5) will have a positive effect on the health of the fish. Need filtering and aeration.
Feeding Danio Aquarium Fish 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.
Two males are planted on one female for spawning. Sometimes they practice group spawning with the same sex ratio. Females, like other species of this genus, are susceptible to the formation of a cyst, which makes it sterile.
And since the expression of eggs from small fish is problematic, it is better to select females under the age of one year for spawning. The selection of males is less complicated.
Approximately two weeks before spawning, females are upset from males, kept separately and fed abundantly with live food (bloodworm, pipeker, enkhitrei). During this time, the belly of the female is strongly rounded, which indicates its readiness for spawning.
For reproduction of pink danios, a spawning area of 10 liters per female is settled.
The form of their bodies by nature itself is adapted for rapid movements.
At the bottom of the stack separator grid, which should cover the entire bottom and is located at a height of about two centimeters from the bottom. Instead of separator mesh, you can use small-leaved plants pressed to the bottom by small stones.
Water for breeding pink danios should be fresh settled. Approximately one third is boiled for optimal stiffness.
It is still better to check. It should be no more than 10 ° dH. pH = 7. The temperature at landing in the spawning area of fish should be the one at which they were kept until that moment.
The water level should be no more than 5 – 8 centimeters above the separator grid.
In the spawning area in the evening, the males are placed first, and after a few hours, the females. Set on the thermostat the temperature is 4 – 6 degrees higher.
It should be 26-28 ° C. And after that they turn off the light in the breeding ground.
The next morning, with the first rays of the sun or with the inclusion of artificial lighting, spawning begins.
It lasts for several hours. During this time, the female sweeps up to two hundred eggs gently milky.
After spawning, it is necessary to remove the producers from the spawning area. You can remove the plants and separator grid by carefully and carefully brushing off their eggs.
Incubation lasts about one and a half – two days. And in three or four days the fry will swim, and they will need to be fed with infusoria, Artemia nauplii, living dust.
As the fry grow, it should be transferred to larger feed and to a larger aquarium. Puberty reaches sexual maturity at six to eight months.
Reproduction of pink danios is not difficult, but requires accuracy. And you will definitely be rewarded for your efforts.
The optimal temperature for fish in an aquarium and how to maintain it
About temperature limits for warm and cold-water inhabitants of reservoirs
Tropical and subtropical regions are not characterized by frequent changes in water and air parameters. In Southeast Asia, the temperature range of air is the same throughout the year, sometimes ranges from 3 ° C (26-29 degrees), and the difference in water is almost imperceptible.
In South America, hot and humid, throughout the year to air 25-28 degrees.
There are species of fish that prefer wide temperature ranges, and there are those who live only in a narrow range. Only the fry of most fish are resistant to the drop to.
When the amount of dissolved oxygen in the water decreases, all fish are less sensitive to temperature changes. Hydrobionts get used to high temperatures in a few days, and to cold temperatures – in almost a month.
For normal acclimatization, a gradual increase in to 1-2 degrees, and a decrease in 0.5-1 degrees is necessary.
Watch the video about the aquarium heater.
All fish species have their own upper and lower threshold to. Fish are sensitive to those parameters that go beyond the permissible limits.
When the border is violated by several degrees, the health of the fish deteriorates dramatically. Frequent and sudden changes in temperature adversely affect the health of pets.
In order to maintain an optimal temperature regime in an aquarium, you need to familiarize yourself with the allowable temperature conditions for warm-water and cold-water fish.
For warm-water fish to water below 18-20 degrees is considered unacceptable. In aquarium fish in this category it is possible to survive in the lower ranges for a long time.
But this fish needs a lot of oxygen and space, good aeration is necessary.
For cold-water fish suitable aquarium without heating, 14-25 degrees for them – the maximum. They also need an abundance of dissolved oxygen.
Is it true that cichlids tolerate different temperature ranges?
Aquarium danio fish are completely unpretentious in care and their maintenance at home is subject to even the most inexperienced beginners. The aquarium will fit from 50 liters of elongated shape, which is important to keep with the lid closed so that the fish do not jump out.
School danios love to swim in a group, so you need at least 6 of them.
For a soil base is better to take small stones and gravel. Plants can choose any, but not plant them too much space, as the fish need space and good lighting. The same applies to the decor of the aquarium, which should be laid out at the edges.
It is undesirable to plant floating plants, as danios used to stick in the upper layers of water. It is necessary to take into account the correct compatibility of the fish with other inhabitants of the aquarium, so that there is no competition in the occupation of a personal area or layer of water.
The most appropriate water parameters will be the following: the temperature regime should be changed depending on the season, in the summer of 20-25 ° C, in the winter of 17-21 ° C. Acidity 6-7.5, hardness not more than 10 °. It is important to regularly replace a quarter of the volume of water and high-quality aeration with filtration.
It is possible to improve the content of danios by means of a pump-filter, thanks to which the fish will feel the flow of water as in natural conditions. Fish danios live up to a maximum of 6 years.
For the prevention of diseases danios, in the aquarium need good aeration and clean water. Also the cause of the disease may be overfeeding fish.
One of the most common diseases in danios is bug-eyed, in which their abdomen increases and their eyes bulge.
Trichodinoz disease is provoked by an infusorium that enters the aquarium together with non-disinfected plants or soil. All treatments are performed in a quarantine aquarium by adding salt and changing water every 2 days.
Excellent swimmers, rapidly and abruptly changing the direction of movement, danios love space and usually live in the middle part of the water.
Aquarium. Therefore, a long rectangular aquarium with a capacity of at least 50 liters is best suited for their maintenance.
It is possible to lay small pebbles or coarse-grained river sand on its bottom, and also to dissolve small-leaved aquatic plants. For danios pink it will be exactly what you need.
Lighting. It is necessary to take care of him. If you place the fluorescent lamp closer to the front wall of the aquarium, the appearance of the pink-pearl moving creatures will only benefit from this.
It is also recommended to illuminate the aquarium with natural sunlight, at least 2-3 hours a day.
Temperature. There are no special temperature requirements for these fish.
They feel good in water of room temperature (from +20 to +23 degrees) with low salt content.
Oxygen access. An indispensable condition is a good constant aeration of water, its high-quality cleaning and periodic replacement.
It is advisable to replace from 25 to 30% of the aquatic environment once a week, at least.
Security. The aquarium, where danio pink flocks live, must always be kept under the hood (between the water surface and the lamp), as these frisky decorative carp are not only excellent swimmers, but also excellent jumpers in height.
For breeding danios pink, you definitely need a separate aquarium at the rate of 15 liters of water per 1 individual, since in the total capacity the caviar will be quickly eaten.
The requirement for the amount of water due to the fact that in the mating season, and especially during spawning, the fish are actively moving in different directions.
In order for pets to not get hurt, the bottom of the pit should not contain large stones and soil with sharp edges, it is better to cover it with peristristis, Canadian elodea or moss. And in order for plants not to emerge, you can put small pebbles.
Clean, defended water (2 days is enough) in the spawning area should be made a little warmer than in the main aquarium, raising its temperature to +28 degrees. In this case, the liquid should undergo easy aeration.
In the breeding ground, first one female is deposited, it is well fed, mainly in the root, since it contains the necessary nutrients and there is no fat at all. As soon as the female’s tummy is strongly rounded (in 10-14 days), two males are placed on it.
At night, the light turns off.
The next morning, the female begins spawning, which can last up to several hours. At this time, she randomly tossed from side to side, leaving behind her caviar.
One litter contains from 100 to 200 white-colored eggs, which descend to the bottom of the spawn through the grid cells.
Aeration is necessary to continue, constant lighting is necessary.
The incubation period lasts up to three days. After this time, barely visible fry begin to vyklevyvatsya.
After another day, when they are already moving, you can start feeding, gradually increasing the dose as the offspring grows.
In the initial period, live dust is used as food: the smallest plankton, ciliates, rotifers. Suit and dry egg yolk.
As the babies grow up, they switch to feeding on larger meals.
After about 5 weeks, when the young growth reaches a size of 2-2.5 cm, it can be transplanted into a common aquarium.
For more than 100 years, aquarists in many countries are happy to keep and breed pink danios. Watch for their movement and color overflow can be hours.
Unpretentious bright tomboy rightly are the favorites of both adults and children.
Video about the pink danios, devoted to the basic rules of the content:
- Let’s start with the physico-chemical parameters of water (acidity, the amount of nitrogen compounds, O2 saturation and temperature).
The most important limiting factor is the content of oxygen in the water. Plants and technical means (as additional sources of this gas) make it possible to increase the density of fish landing.
To determine its limit is simple: if the fish try to spend most of the time near the surface, convulsively swallowing the air (with high-quality aeration!), Then you have overpopulation.
At the same time, it is necessary to check the temperature of the water, since when it rises, oxygen dissolves worse in water.
- The next factor is the number, size, weight, age, food activity and growth rate of the fish.
The larger the individual, the more discharge from it. They, as well as food residues, decompose and release toxic ammonia.
If there are too many fish, then he simply will not have time to recycle and will poison the aquarium. The permissible number of fish can be identified by conducting chemical tests of water for nitrogen, ammonia, ammonium, nitrite, nitrate and good results by analyzing the results.
- It is important whether there is soil in the aquarium, what quality it is and in what quantity.
- Do live plants and what kind they are.
- Is filtering equipment used and which; how often the aquarium is serviced (water is replaced, the ground is cleaned, etc.).
- How often and in what quantities the food is given, what quality and chemical composition it has, what percentage of fish they eat. There are other, but not so important factors.
Simply put – you can not put in a 150 liter aquarium 50cm long. 60 Danes are pink, as well as 60 spotted soms on an area of 0.5 sq. M.
To find out how much, you can put in the aquarium and those and other fish, you just need to calculate their percentage for a specific volume of the aquarium.
10 guppies = 100%
6 Swordsmen = 100%
5 guppies + 3 messengers = 100%
