Having determined how much volume of the aquarium you want to have, you can think about the choice of inhabitants for your new aquarium, in particular the choice of fish. The very first urge to go to the store and choose your favorite fish may well end up that they either eat each other or grow to sizes that do not correspond to the size of your aquarium. You need to know which fishes are good for aquarium at home depending on what your future aquarium will be.
Why it is important to think before buying fish?
It is important to think about the composition of the community so that the fish in your aquarium do not become enemies or victims for other animals that have settled nearby. This is a very responsible and time-consuming task. Each species has its own habits, its own living conditions, its own subtleties. They should approach as closely as possible both to the conditions you will provide for them and to the habits of their neighbors.
What to take into account?
The volume of the aquarium is one of the most important parameters that is taken into account when choosing fish. The more fish, the more free space is necessary for their comfortable existence. And the fish feels the presence of other fish. Overpopulation of the aquarium will greatly impair the well-being of your Pets and make it difficult to create and maintain a biological balance.
The rule is very simple: the larger the volume of the aquarium, the more fish it can accommodate. In addition, there are other layers of fish habitat. For example, if you have settled a pair of fish that live in the upper and middle layers of water. Then you can also settle the fish that live at the bottom of the aquarium. Usually, the inhabitants are selected in such a way that one fish could not swallow another. And the smaller the size difference, the better.
It is important to take into account not only the appearance of fish but also their behavior. Fish are very different in nature. There are aggressive and peaceful, social and isolated, sluggish, and playful. In addition to the fact that slower fish, in this case, will not be in a state of stress, such an aquarium will look much more harmonious. It is advisable to select fish with a similar character. You should especially monitor the temperament of fish and avoid situations where peaceful, unable to stand up for themselves fish will fall into the same aquarium with aggressive ones.
Each fish feels comfortable in a certain environment. For example, if some fish feel good at a low temperature, then heat-loving fish should not be settled with them. It is important that the fish fit the water of your aquarium: it should be almost the same as the one they are used to. Salinity, temperature, acidity, as well as the water change mode-all this should be comfortable for your Pets. Now many species of fish are bred in aquariums, so for several generations, they get used to the parameters of tap water. But fish caught in the wild must gradually adapt to the water, and the closer the parameters in the aquarium to the parameters of the” home ” fish, the more likely it is to successfully adapt and will be good for aquarium at home.
You need to decide whether there will be plants in the aquarium. Some fish see the improvement of the aquarium in their own way and are able to move stones in their own way, dig up plants, and some can simply eat them or spoil them.
Flocking fish are most suitable for aquariums, which will be home to several different species. Species flocks of fish are sometimes organized hierarchically, obey the dominant and exchange signals that are invisible to us, which coordinate their actions. Depending on the volume of the aquarium, it is possible to have two or three flock fish of 6-12 type. If desired, you can always add a few single fish.
Tips for choosing fish in an aquarium
To know hich fishes are good for aquarium at home, you should consider the following-it is undesirable to keep together fish incompatible with the conditions of maintenance, feeding, and breeding.
• Explicit predators and their victims must not be kept together. Sometimes the neighborhood with implicit predators ends badly.
• You can not combine fish that need different biochemical parameters of water. Trying to keep Malawian cichlids and discus together won’t do any good. The body of these fish is designed for different osmotic pressure (stiffness) and acidity. So either one or the other will be oppressed. Changing water parameters is difficult, troublesome, and expensive for a beginner.
* It is necessary to purchase mainly carnivorous or herbivorous fish. These fish have a different structure of the digestive system, and, consequently, the need for different food. It can be quite difficult to provide proper feeding for both.
• Do not combine the heat-loving and cold-loving fish. Discus and goldfish in the same aquarium, not quite the right neighborhood. Discus needs a temperature of more than 28°C, and goldfish about 20°C.
• Do not keep schooled fish singly or in pairs. Five neon tetras in the aquarium is not a flock. In such numbers, they will always feel uncomfortable. But the flock is more than 10 pieces and looks more beautiful.
• You can not contain single, territorial, etc. fish in an amount exceeding the capabilities of your aquarium. In a small aquarium, two large labeos are unlikely to get along.
* It is undesirable to keep aggressive and quarrelsome fish together with calm and veiled forms. A flock of Sumatran barbuses quickly nibble the fins of scalars.
• It is useful to take into account the natural desire of fish to get offspring. Many of the fish, forming a pair and preparing the territory for spawning, make the other inhabitants sit in the corner of the aquarium.
How many fish can your aquarium hold?
Recommendations on which fishes are good for the aquarium at home are such as centimeter of fish per liter of water are fairly approximate. There are several additional factors to consider. Of course, all calculations are made for the size of adult fish, and not for the teenagers you buy. Otherwise, as your pets grow up, the aquarium will become overpopulated.
First. Fish differ in their habitat layers. If by calculation you can put 20 fish in Your aquarium, this does not mean that you can start 20 catfish living on the bottom. It is not difficult to distinguish fish living in different layers.
It tells you by the structure of the mouth: • If the mouth opening is directed upwards, these fish are inhabitants of the upper layers of water. And take food mainly from the surface of the water; • if the mouth is directed along the midline of the body, the element of these fish is the middle layers. They take food in almost any layer of water • * the Mouth opening directed downwards distinguishes the bottom inhabitants. They only look for food at the bottom.
The second is territoriality. Many fish require a certain territory. Moreover, it can not allow both representatives of their own sex or species and other fish.
Third-equipment. An aquarium with a good biofilter, denitrifier, good oxygen saturation, and other modern and efficient equipment is able to accept a larger number of fish.
The fourth is the presence of living plants. Plants release the necessary oxygen to fish. They consume organic matter released by fish. In addition, they are the main or additional food for many fish. In addition, plants act as shelters and delimiters of habitat zones.
Fifth-features of reproduction. Many of them, occupying the territory for laying eggs, simply do not leave living space for other aquarium inhabitants.
Sixth. The presence of snails in the aquarium also has to be taken into account. Quite often, so many of them are bred that even with a small landing of fish, the aquarium is overpopulated.
