How to feed aquarium fish?
It is amazing how many people in the world strictly follow a diet and regularly support their health with vitamins, and at the same time give their fish only ready-made food, and of one kind.
Such feeds can be compiled on the basis of scientific recommendations and include a huge amount of nutrients, but they are only simple substitutes (and often inferior) of what fish find and natural conditions. Do not think that we are against the finished feed, quite the opposite. However, one thing should be very clear: ready-made food is usually sufficient for normal existence, while live food in frozen or freeze-dried form is absolutely necessary for bringing fish to spawn.
For each type of fish need a certain feed. Let’s talk about the basic rules of feeding.
The size of the feed should match the size of the fish. If they do not cope with food or chew it, spit it out, it means that it is unsuitable. The size of feed for fry should be approximately equal to the size of their eyes. Bloodworm, tubule and enhitreya can be given cut into small pieces. Some aquarists do not feed a pipemaker with valuable fish for fear of poisoning.
Feed quality is of the utmost importance. Therefore, dry food should be really dry, and not sticking together, living organisms. to be active. Frozen feed should be fed immediately after thawing.
The amount of food needed by the fish is determined by amateurs on the basis of their own observations. Live food is best given in small portions. Feed should be given in small portions several times a day. One-time feeding of a triple in volume portion does not equal three more modest feedings. Initially, the fish pounce on him, then their activity drops markedly and, therefore, you can stop feeding. If the dry food placed in the feed ring is not eaten within 5 minutes, the remnants should be removed with a net and reduced further. You should always remember that it is better not to feed than to overfeed the fish, otherwise they will be worse painted, become lethargic, stop spawning, their lifespan will noticeably decrease. Fish should be given a variety of food, constantly alternating it.
Adult fish should be fed 1-2 times a day, at the earliest one hour after turning on the light and at the latest one hour before turning it off. You must ensure that everything is eaten completely within 15-20 minutes. The daily ration should be 5% by weight of the fish. The feeding place should be permanent. Remnants of uneaten food should be removed, this is especially important when using stale feed, as they can cause such unpleasant phenomena as turbidity of water, soil rot, appearance of foul-smelling algae. Therefore, they need to be immediately assembled with a hose. Once a week you need to arrange a hungry day. Fry should be fed as often as possible.
Here are six of the most important rules to follow when feeding aquarium fish:
- When feeding, be guided by the requirements of the fish, and not by your own desires.
- It is desirable to feed (better, of course, live) a variety of feed, making the most of the possibilities of each season. Live food in its raw form is more beneficial than boiled. Even the best feed is no good if it does not alternate with other feed.
- Do not feed too plentifully! Remains of feed spoil the water. In aquariums, fish are more likely to die from obesity than from malnutrition. Determine how much live fish feed is able to quickly eat, and never give them more than the norm. Fish that eat right can endure a week-long hunger strike without harm.
- If possible, feed several times a day.
- Feed size should be consistent with fish size. Large fish will starve if they are fed small food; For small fish, large feed is too tough, they cannot swallow it.
- Watch the fish during feeding, at this point it is easiest to distinguish sick fish from healthy ones.
The size of the feed should match the size of the fish. Live food is best given in small portions several times a day.
Hunger can have a beneficial effect on the sexual activity of fish and even help restore the ability to reproduce. Fasting normalizes the biochemical processes in the body, helps to eliminate poisons and slags, utilize fatty and weakened, painfully modified tissues, and resorption of female genital products remaining in the body (unwashed caviar), without which a new portion of caviar cannot be formed.
How to feed aquarium fish
The only way to ensure the fish harmonious growth and development. to feed them correctly. In nature, each species feeds on a certain type of food, in the conditions of an aquarium they have to adapt to different food and diet. Therefore, their health and longevity will depend on how to feed aquarium fish.
Feeding depending on the type of fish
The organization of proper nutrition begins with finding out the food supply in natural conditions. This should be done before completing the aquarium and choose fish with similar rations, which will help to avoid malnutrition or overeating pets.
Fish are conventionally divided into 3 types:
- predators have a roomy stomach, which means that feeding should be carried out in large portions a small number of times;
- Herbivorous species need frequent feeding in small volumes, as they have a long digestive tract, designed to digest plant fibers;
- omnivorous individuals adapted to absorb any kind of food.
The size of the fish influences the diet and diet. If large and small individuals live in an aquarium, it will be difficult to organize their feeding correctly. There is a risk that large individuals will eat small ones.
Feeding the young
The most difficult in the organization of food is feeding the fry. Within 2-3 weeks requires a constant change of types of feed.
The larvae of fish that have just hatched from the eggs are fed with composite feeds, which include algae, yeast, beef heart, and liver. Single-species feeds are also popular. algae, Artemia larvae (nauplii), rotifers. The fry have a small mouth, so they are regularly fed with powdered milk, powdered food and small plankton, rarely crushed egg yolk.
In the first seven days of life, the young are fed with powdered food supplemented with vitamins and live food (crushed bloodworm, carretra).
They give small granules, which, unlike fish flakes, quickly eat up and thus prevent their nutritional loss in water.
The number of meals is different in fry and adults. Young fish are often fed 3-4 times a day in small portions so that the food is eaten quickly and the water is not contaminated by food debris. Adults are fed 1-2 times a day, not more.
The amount of feed should be such that the fish have time to eat it in five minutes. Remains of feed will instantly spoil the water. From this fish can hurt and die. The exception is the catfish, which for a whole day may not leave their shelters.
Feeding is carried out at the same time, as the fish quickly develop a conditioned reflex.
Proper feeding of aquarium fish is based on three basic rules:
- time for eating no more than 5 minutes;
- prevent overeating;
- filtering systems at the time of feeding should work.
To understand that fish overeat, you can on the following grounds:
- turbidity of water;
- fish rise to the surface and breathe heavily;
- the smell of tina or fish from the water;
- the appearance of algae on the glass;
- bacterial film on the surface and walls of the aquarium
- mucus on aquarium plants.
Feed types, nutritional needs, nutritional alternatives
Aquarium content makes it impossible for fish to regulate feed intake, as they do in their natural habitat. Thus, there is the likelihood of nutrient deficiency.
The nutritional needs of different fish are very different. Some species consume minerals through the gills, the second need a large amount of vitamin C and unsaturated fatty acids. Someone needs the required amount of food per day at 3.8 mg per gram of body weight (blue neons), while others, for example, goldfish. 25 mg
Proteins and amino acids
In varying degrees, fish need protein and amino acids that affect their height and weight. In general, the need for protein in most aquarium fish ranges from 25 to 55%. So, for a positive weight gain, goldfish need feed containing 53% protein, red-tailed barbs. 41%, lyalius and scalar ordinary. 25-26%. Excess protein can also have negative effects. For example, if a barb is fed with food in which the percentage of protein content exceeds 50%, then this will lead to a significant weight loss.
It is important to bear in mind that protein sources of marine origin affect weight gain more than plant sources. If both species are present in the feed with a share of 45-55%, the fish develops faster.
The level of protein affects fertility, especially in the species of the family of atsiliy or gambusian, which are very popular with aquarists. Protein content over 30% is a certain guarantee of the appearance of offspring. Food with low protein content (20%) leads to its low content in eggs.
Protein is better absorbed when fed with the following foods:
- fish flour;
- beef heart;
- casein feed.
The protein contained in wheat and soy is poorly digested and less easily absorbed.
Normal growth and survival of fish provide fatty acids. an important source of energy. Freshwater fish are most in need in linolenic acid, the source of which is vegetable oils. Linolenic acid also improves reproductive function.
Feed, characterized by a high content of fatty acids:
- beef liver, heart;
- mosquito larvae;
The leader in the level of fatty acids from the list is beef heart.
Minerals and Vitamins
Most fish need vitamin supplements. Their choice depends on the type of fish, size, food, health. Ascorbic acid is most often added to the diet. Vitamin C is responsible for excretion of foreign chemicals and the production of enzymes involved in metabolism.
Lack of ascorbic acid leads to a decrease in weight gain, curvature of the spine, jaw, gill covers, pegling, color change.
Ascorbic acid over time loses its activity, so food supplements with its content should always be fresh. Fish can absorb minerals through the gills and intestinal epithelium.
The following minerals are considered the most important for the inhabitants of the aquarium:
The concentration of phosphorus is lowest in water, therefore it is contained in many feeds as an additive. Lack of phosphorus causes bone curvature and loss of appetite.
The color of the skin and muscles of fish depends on the amount of carotenoids in the diet. In addition, they affect reproduction, the immune system and overall development. Fish can not produce carotenoids on their own, so they must receive these elements with food.
Natural sources of carotinoids are:
- Chinese rose (petals);
- calendula (petals).
The greatest influence on the intensity of color affects chlorella, related to single-celled green algae.
The presence in the diet of live food is necessary for predatory fish, especially during spawning. This food helps to increase the number of fry.
For food most often used the following feed:
Live food has a high nutritional value. Experts advise to consider Artemia as a live food of a cysts without Artemia. They are distinguished by good survival and high growth rates. But it is very difficult to ensure the safety of the fish when feeding them with live food. There is always the threat of introducing various types of bacteria into an aquarium.
In a specific aquarium, food should be varied and each type of food should be introduced consistently and in portions. It is difficult and not practical to satisfy with nutrients different types of fish living in the same aquarium. Therefore, many aquarists use universal feeds for feeding.
How to feed aquarium fish correctly?
Aquaria. a great hobby, suitable for both children and adults. Firstly, it allows you to raise your own self-esteem. Looking at a beautiful, well-kept aquarium, one can not but be proud of the fact that it was you who created such a masterpiece. Secondly, if you watch fish for five to ten minutes a day, this allows you to normalize pressure and reduce your pulse, that is, calm down wonderfully by refusing special medicines.
But, of course, to the inhabitants of the aquarium pleased you, you need to know exactly how to feed the fish. First of all it depends on what kind of fish you breed. After all, some people are happy to eat plant food, while others only live food. Some fish need a lot of protein, while others need a lot of carbohydrates. Therefore, the diet should be chosen individually for each breed.
However, there are general rules. Depending on the size of the fish, select the size of the feed.
If you use dry food, then for large fish (angelfish, goldfish, gourami) you should buy pellets. small fish food is simply not noticed, and it sinks to the bottom, poisoning the water. But for guppies, swordtails, danios and neons, small food is better suited. large particles cannot be swallowed.
When feeding is very important to comply with the regime. It is best to feed the fish twice a day, and try to do it at the same time. You can even develop a conditioned reflex. lightly tap on the glass during feeding. Then after such clicks, the fish will immediately gather near the feeder and everyone will get about the same amount of food. Also, if you want to know how to properly feed aquarium fish, then do not forget about fasting days. Alas, most of the fish have little control over themselves while eating.
So, if you do not feed them one day a week, it will be beneficial. problems with obesity and liver diseases, which are especially common in sedentary fish living in small aquariums, will be excluded.

Many novice aquarists want to feed their brand new favorites to satiety. After all, they ask so, they always want to eat, and then it is so interesting to watch when the fish is hunting for a worm.
But such a diet can not only badly affect the health of your fish, but can also harm them.
Since the number of fish species is very large, the feeding methods as well as the compositions and the amount of food are also large. But do not fall into despair, there are common methods of feeding that will help you avoid trouble and frustration. Let’s look at them.
The first and most important rule: it does not fatten the fish to such a stage that it will simply lie at the bottom of the aquarium in its belly. You need to feed in moderation, adult fish will be enough to feed once a day. It is also necessary to understand that the fish are not equipped with brakes, which means that as long as she sees food she will not stop. Overfed fish may become fat, lose the ability to become pregnant and may die early. Carp species fry very quickly. And besides these problems, the food can simply get stuck in a place where the fish will not reach it, and the water will start to deteriorate very quickly. Best of all, throwing fish food in small portions, so that as long as it falls to the bottom. the fish could eat it completely. It is advisable to go on a hunger strike once a week for your fish.
Consider the second rule: a variety of menus. Most fish feed on live food, such as a pipe worker or a bloodworm. But it doesn’t hurt, and some fish even need vegetable feed. You can use a scalded salad or vitamin supplements as herbal supplements. No need to feed the fish only dry food. This can adversely affect their health!
Before you give dry food to your fish, it is advisable to place it in a separate container with some water for several minutes, after the particles of the feed swell, you can safely give the fish. This is done so that the food is not swollen in the belly of your fish!
Consider the third rule: at the expense of the correct choice of food. Here we consider feeding the young. A frequent question for novice aquarists is: “when to switch from one fish food to another when fry are raised?”. For convenience and confidence, you can take as a rule the following: the size of the feed particle should not be larger than the eye of the fish itself for which this feed is intended.
As mentioned earlier, due to the large number of species, there is an even greater diversity in feeding. But until you know exactly what is best for your fish, you can follow these not complicated rules to avoid sad consequences. Good luck!
