Aquarium fish for beginners must withstand fluctuations in water parameters in a new aquarium and resist diseases caused by stress. Behavior is also important - peaceful, livable fish are the best choice for a beginner.
Often they forget about such a factor as the ability of fish to adapt, not in terms of water, but in terms of a new environment and new neighbors. You can also read: 10 best fish for beginners
New aquariums are very unstable due to the fact that the necessary microflora (useful bacteria that remove harmful substances) did not form in them. And even if bacterial preparations are added (they are sold at pet stores), the conditions may not be suitable for tender fish.
Some fish, especially large ones, live perfectly in almost empty aquariums without decor and neighbors. To others, such conditions will seem terrible and they will fall into stress, despite the excellent water parameters, they will fall ill and die.
For them, the presence of other fish in the aquarium is a sign that the environment is safe. So, a good choice for a beginner aquarist is a fish that is simple, disease-resistant, resilient, active and not aggressive.
Find out the parameters of your water
Knowing exactly the state of the water in the aquarium is very important, in order for it to be in normal condition, you need to periodically measure the level of Ph and hardness. Knowing in advance what kind of water you have, you can choose the species that are suitable for you, since for some fish the parameters may not be suitable, and if you put them in such water, the fish may die. Now you do not need a chemical education to do this, it is quite enough to buy a set of tests in a pet store. Better drip, they are more accurate.
Read about fish before you buy
Unfortunately, newcomers often lie and sell incompatible species, either fish that are not suitable for beginners, or very large species. Sellers are not conscientious and in order not to become a victim of fraud, you need to prepare.
Choose several types of fish that you like, you can see in pet stores or in the market. And carefully study the information about it, since now there is the Internet. This will give you a lot of experience and understanding whether this particular fish is suitable for you.
The main questions are the size to which the fish grows, the nature, the requirements for water parameters, and how to stay - alone, in pairs or schools?
Think about the future
Most of the fish you buy in the future will grow, change their behavior, or even color. Therefore, you should know exactly what a cute little fish will turn into over time, and whether there will be enough room for it.
Do not buy fish that will outgrow your aquarium, even if you are sure that this aquarium is temporary and you will definitely buy a larger one. Looking into the future will also help you pay attention to views that you did not find attractive.
For example, the iris in adolescence is a plain-looking fish. But when they grow up it is a bright and very beautiful fish that adorns any aquarium.
Be careful with deformed views
A careful study of the fish that you liked at first sight may surprise you quite a bit. For example, when buying a three-hybrid parrot for the first time, few people know that it is the result of artificial selection of three different species of fish. And that its unusual shape is the result of deformation of bones and internal organs. If they knew, maybe they would refrain from buying.
Now there are a lot of fish of unusual shapes and colors. But, often, this is all the result of selection and interference in nature. A deformed skeleton, organs and low immunity are the result of the intervention. Avoid these types of fish initially.
Also, do not take fish whose color seems too bright. Unscrupulous sellers specifically stimulate fish before selling, and yet being in the crowded and bustle of the market is stressful for fish. And usually she reacts to it becoming less bright than in the aquarium, and not vice versa.
Fish grow as much as the aquarium allows, but at the same time it has deformed internal organs, health problems. As a result, the skeleton twists, the immunity practically disappears and instead of a beautiful fish, a twisted freak turns out
Most fish will grow to their maximum redistribution, perhaps a little less than in a spacious aquarium. For example, a shark balu, growing up to 30 cm, in a small volume can grow up to 25 cm.
Tips for choosing the first fish
Avoid fish with a specific diet - usually food, the main source of problems in the aquarium. The first 6-8 months you need fish which will be enough for conventional feed - cereals, for example. After six months, the diet can be improved and diversified with the widest possible range of feeds.
Do not buy too many fish at once. Although an aquarium with several fish does not look very spectacular, try to add fish slowly, without risking losing all of the disease at once, for example. An approximate rule is no more than six small fish per week.
Ask the store how long the fish has been kept in the exhibition aquarium. Recently added is better not to take, two transplants in a short time, too much stress and can lead to problems.

Popular fish, such as guppies or neons, are actually far from the only option for beginners. In order to choose the right aquarium fish, it is important to understand the difference between the one that will take root in the new aquarium and what will hurt.
So, now let's take a look at guppies, especially their thoroughbred forms. Natural guppies, strong and hardy like no other fish. But, intensive crossbreeding, mixing of related breeds has led to the fact that thoroughbred guppies can die from a draft.
Inbreeding, the lack of natural selection, almost sterile conditions in the aquarium, led to the fact that the guppy's immunity is extremely weak. And the slightest bacterial infection, sometimes mowing the aquarium completely.
In well-balanced aquariums, a thoroughbred guppy lives quite a long time, up to two years. But in the new aquarium, the balance is too weak to start with this fish. Other live-bearers, however, are quite strong fish and are quite suitable. Even non-pedigree guppies are a good choice.
The second most popular fish are neons. Wonderful, beautiful fish, but a little timid and sensitive to fluctuations in water, as well as to diseases. In a stable aquarium, a flock of neon can live for several years without any problems, but in a new one it can melt in a few months. Other small tetras, the same timid, if they are not kept in a flock of ten individuals, and it is better to buy them later.Neon
Catfish, usually corridors, are often bought in a new aquarium. Why don't they fit? After all, it is a peaceful and accommodating fish that tolerates various conditions quite well.
The problem is that they need to be kept in a flock, and fed with various sinking feeds. And in a new aquarium, feeding a group of fish with protein-rich food can lead to overfeeding, and a sharp increase in toxic substances - ammonia and nitrates.
Other catfish that feed on algae are anticycrus, loricaria, otocinclus. They will simply be short of food.
A couple more species of fish that can be problematic:
Hybrids - fish obtained as a result of selection, as a rule, have weakened immunity and are demanding of conditions. For example, discus discs (never take them at all if you are new to aquarium), bright forms of guppies.
Large species of fish are usually aggressive, they also should be brought first.
What remains? Yes, many species. For example:
Guppies of simple breeds are an amazing example of unpretentiousness.
Mollinesia is a charcoal black beauty and not demanding on conditions.
Large gourami, such as marble ones. They can live practically without oxygen in the water, but are more suitable for aquariums with a large number of plants and shelters.
Males, very beautiful and undemanding. Just do not plant them with your own kind!
Swordsmen and Pecilia are active, vibrant and accommodating.
Danio - grace and small size.
A good choice is also the fish of the iris family, these are peaceful and undemanding fish, although they prefer hard water and active neighbors.
Most iris flowers reveal their potential in coloring a few months after being placed in the aquarium, and at first they may look inconspicuous.
