Hello, Valeria! In fact, the requirements for housing and feeding conditions are different for different types of fish. Amateur beginners of aquarium fish, as a rule, pick up fish depending on their decorativeness. “I liked it, I didn’t like it”. Therefore, of course, it is impossible to provide all these variegated fish with suitable housing and feeding conditions for people. Of course, it is difficult to maintain optimal conditions for keeping different species of fish, but many species are distinguished by their ability to adapt to the conditions of the environment in which they live. In one aquarium should be kept fish, similar in size and habits. Large and small species of fish, predatory and peaceful, cold-water and warm-water, slow-moving and fast are incompatible in one aquarium. Most successfully coexist species, the roads of which do not intersect, that is, they live in the same aquarium, but live and feed in different ways, without interfering with each other. Selecting fish for an aquarium, first of all, you need to take into account your own capabilities, that is, whether you can keep this or that type of fish in your aquarium, and then divide the fish into groups that require similar maintenance conditions. In addition, there are many nuances and subtleties that you need to know before you decide to buy fish. For example, there are fish living in schools, and they should be kept in schools. Fish living in pairs must be kept in pairs.
Tap water contains chlorine and chloramine, which makes it suitable for human consumption. These substances are poisonous to fish and can damage the fish or even kill it. This problem can be solved by settling for 1-2 days, boiling, aeration, filtration through activated carbon, various chemical preparations. But since you are new to this business, use the simplest methods, without resorting to chemistry.
For an aquarium water is needed that meets the following requirements: clear, clean, with dH 5-20 °, pH 6.5-7.5. Choose fish that have natural water that has chemical properties (pH and GH) similar to your tap water. If your water is hard, choose a fish that lives in hard water. If you have soft water, choose fish living in soft water. This is especially important if your water is outside the 6.5-7.5 pH range. Changing the natural hardness (or pH) of your tap water can be a very difficult job and often discourages the pleasure of maintaining an aquarium. In addition, inept attempts to change water parameters often turn out to be worse for fish than initial water conditions.
After pouring water into the aquarium, various processes begin to occur in it. Water can become whitish-cloudy due to the onset of decay processes of dead plant parts and the reproduction of microorganisms. After 2-3 days, the water will again become transparent, but to speed up the appearance of a favorable environment for fish life, it is recommended to add some water from a long-established prosperous aquarium. If you lean over a normally functioning aquarium, you can smell the plants. Any other odor, like ammonia, hydrogen sulphide, indicates the disadvantage of the processes taking place in the aquarium. In this case, it is necessary to clean the soil and replace part of the water.
Transplant fish in the aquarium.
It is safe (so as not to create stress to the fish when conditions change) this is done in the following way:
- If you bought fish in the winter season, remember to prevent heat loss while you carry the fish home.
- Do not pour into the aquarium the water in which you brought fish or invertebrate.
- Aquarium lighting should be turned off.
- Place the jar of fish in the aquarium so that the temperature levels out.
- Add a little water to the jar.
- Hold for 5 minutes and repeat the previous action and wait 5 minutes.
- Gently release the fish into the aquarium.
- Do not feed the fish for several hours.
Changing the water in the aquarium often and completely should not be. About the rules of water replacement read the links that are listed in the "sources" below on the same page.
