How To Translate (Move) Fish In The Water Of Your Aquarium

Relocation of fish from one aquarium to another.

Transfer of aquarium fish to other water.

So, the fish are not poured together with the water in which they came, right in the new for them aquarium. Sensitive species from this often die (either immediately or after a few days, or even weeks, from the irreversible destruction of the gills), and the fish will not die stronger, but can then get sick for a long time.
Usually, when transferring fish, two most important parameters for this moment are taken into account: pH, or the active reaction of water and its temperature.
In the autumn-winter period, when there is every reason to believe that the fish will be brought in already fairly cooled water (although you should take all possible measures so that the water does not cool!) Do not pre-heat the water in the quarantine tank. Let her temperature be room temperature (about 21-23 ° C). As a rule, fish can be brought home at a temperature not less than 20-18 ° C. In this case, that is, when the temperature difference is not more than 3 ° C, the translation process will take relatively little time (approximately 20. 30 minutes). Aeration and filtration systems in the quarantine vessel should be switched on no less than one day before the landing of the fish. But do not turn on the heating pad in advance It will need to be included after the fish are transferred to the quarantine capacity.
The technique of transferring fish is widely known when an indoor shipping bag is allowed to float in an aquarium to equalize the temperature of the water. There are a number of drawbacks to this method: the toxicity of ammonia and carbon dioxide accumulated in a confined space increases as the temperature of the water increases, and pH does not even out of oxygen. From such actions aquarist fish often suffocate and die. It is a shame to bring the fish home alive and lose them when most of the difficulties were already behind. therefore the bag must be opened and the air sprayer must be dropped into it. Aeration will saturate the water with oxygen and will take carbon dioxide out of it. Here only with a floating package it is very inconvenient to carry out these manipulations. Look, he will drown, and the fish will be in the new water without adaptation. In the transparent bag floating on the surface, the fish feel very uncomfortable, they can start to beat, try to go to the bottom of the aquarium (it can be seen through polyethylene) and get hurt about each other or about the sprayer. Therefore, we proceed differently. Even before you go for the fish, let’s make a simple device from a plastic bottle from drinking water. Let us cut off a five liter bottle in its upper third, and blacken the walls from the outside with a felt-tip pen, writing in indelible (alcohol soluble) ink. You can not paint over the walls of the container, and put it in a dark plastic bag.

After providing the fish with aeration, we immediately add to the package means that neutralize ammonia (anti-ammonia or ammonia), and then a soothing STRESS COAT conditioner (only 3-4 drops per 1 liter of water are needed). Practice has shown that this significantly facilitates the adaptation of fish, but you can do without these drugs.
Now measure the temperature of the water in the transport package. If it is not more than 3 ° C different from the temperature of the water in the quarantine capacity, then we do not specifically undertake anything. If the difference is more than three degrees, then in order to ensure sufficiently fast, but not sharp, heating of water into the auxiliary tank for receiving fish (but not in the package itself!) we pour about the same volume as in the package itself, the volume of water heated to 26-27 ° C. It can be taken from the main aquarium, where it is usually just heated to this temperature.
And finally, let’s measure the pH. If the difference with the water of the quarantine aquarium is no more than one unit of the pH scale, then there will be no particular problems with the transfer of fish. In this case, it is necessary to pour into the transport package one quarter of the volume of water already present in it, taking water from the quarantine (aquarium).
After 10 minutes, it is necessary to increase (once again water from the quarantine) the volume of water in the package by another quarter, and after another 10 minutes, again measure pH and temperature. If the difference in pH values ​​is imperceptible or slightly noticeable (the colors of the indicators are the same or very similar), and the water temperatures in the package and in the quarantine capacity will not differ from each other by more than 1 degree and a half, then catch fish with a net (do not pour it out with the water in which they came!) from the shipping container and move them to the quarantine container. Thus, the transfer of fish will take about 20 minutes or a little more. It should be noted that to delay the process of translation at close hydrochemical indicators of water is not only meaningless, but also harmful. In a very small transport package, the fish are very stressed, can beat and damage each other. Males of cichlids or labyrinth fish can "intentionally" kill or hurt each other or females. And although the dark walls of our "transfer device" have a calming effect on fish, the above circumstances should always be borne in mind.
Quite another (and incomparably more complicated) case is the transfer of fish from water to the input with a difference in pH values ​​of more than 1.5-2 units. It should take at least an hour, while adding new water in very small doses at intervals of 10 minutes or literally drop by drop (drop per second). In case of expected significant pH drops, it is more correct to use special reagents (pH-plus or pH-minus) in advance to set the appropriate values ​​of the active reaction of water in the quarantine tank and transfer the fish in the same 20 minutes. within a few days to achieve the desired pH level.
What should I do if the fish on the way have cooled down very much (arrived at a water temperature of less than 18 ° C and the temperature difference in the package and in quarantine is 3-4 ° C or more?
Look at the condition of the fish. If they initially lay on the bottom on the side, and continue to lie 12-15 minutes after adding air conditioners and topping up warm water in a "transfer device", then add a little brandy to the bag. You need to use a syringe and add no more than 0.5 ml per 1 l of water. As a rule, this allows you to revive the frozen fish in 3-5 minutes. Then start adding water from the quarantine to the transport package for approximately one-fifth of the amount of water it contains at one time. The interval is 10 minutes. So it is necessary to act until the temperature and pH of the water in the transport container and in the quarantine container are equal.

At the same time, the water level in the package can greatly increase and the living fish will have the opportunity to jump. In the presence of aeration, you can do as shown in the photo above. This is another advantage of using a "transfer device". Labyrinth fish should always have free access to the surface of the water and closing the package should pay attention to it.
In practice, the temperature levels off fairly quickly, but the pH is not always. Sometimes water has to be poured and poured. At some point there is nowhere to pour, and the water in the bag is still too acidic. Here it is necessary to scoop excess water with a small cup, leaving the bag filled only by a third and continuing to pour water from the quarantine tank at intervals of 10 minutes.

In a teaspoon, about 4 grams of calcium chloride granules are placed. This amount is enough to raise the hardness of 100 liters of water by about 2 ° GH. A 10% solution of calcium chloride would require 40 ml.

Flag-colored multi-colored patzilia (Xiphophorus variatus) are relatively unpretentious fish, but they will feel bad if they suddenly find themselves in soft and acidic water. Small supplements of calcium chloride (6-8 g per 100 l) will greatly facilitate and accelerate the process of adaptation.

In conclusion, I would like to wish all readers success in adapting and quarantining their new fish.

You can take advantage of this advice only when it is easy to set the desired temperature on an aquarium heater and when there is confidence that it will maintain the desired temperature. Otherwise, you can simply cook the fish. For small aquariums, which are mostly quarantine tanks, the accuracy of the heater is especially important, since it is very easy to overheat them. If you are not sure about the heater being used, first set its degree thermostat to 22-23, after a few hours measure the water temperature and twist the regulator to the desired side (usually you should try to set 25-26 ° С). It may take many hours to accurately adjust the water temperature to the desired value.

The level of fresh water salinity (TDS) can be estimated by its conductivity using a special instrument. a conductometer. It is not cheap, but it can be very useful for those who are seriously engaged in fish demanding the hydrochemical composition of water.
