Bryozoans (Bryozoa) in the aquarium

These creatures are very similar to tentacles, the size of Bryozoans is from 1 to 3 mm, they grow in a colony, which is why they are very similar to coral, white creatures similar to bryozoans were seen by the audience of the movie Avatar 🙂

Should I fight bryozoans? In answer to this question, the opinions of aquarists differ, on the one hand, they eat ciliates and bacteria, this is useful, which means bryozoans. assistants and do not need to fight. But care must be taken that they do not accidentally populate the filter sponges and begin to feed on nitrifying bacteria. If there are too many bryozoans, more frequent water changes and cleaning the aquarium will help.

Hydra in the aquarium

The first truly dangerous uninvited aquarium guest on our list. Remember the myth of the Lernaean Hydra, it immediately becomes creepy, isn’t it?

Hydras. coelenterates animals ranging in size from 2 to 20 mm. This name speaks for itself, hydra. actually a digestive system with the ability to reproduce. At one end, it is attached to some object, for example, a stone, and catches prey with its tentacles. Eat the hydra fry. worthless. It can also harm adult fish. causing damage to them with stinging cells located on the tentacles. Hydra has two ways of reproduction: division (budding) and normal sexual. That is, if the hydra is cut in two. you really get two hydras like in the myth. Hydras are brought into the aquarium mainly with natural decorative objects that have been poorly processed.

Water donkey (Asellus aquaticus) in the aquarium

Water donkey (Asellus aquaticus) in the aquarium photo

A representative of the order of isopods crustaceans, ranging in size from 1 to 2 cm, can be brought in from stagnant, slightly swampy reservoirs, where it eats away rotting organic matter from the bottom. It is quite simple to recognize a water donkey: by two pairs of antennae-antennas. One of the pairs is short, the other. almost as long as the body of a crustacean. The eyes are faceted, the body is clearly segmented into 8 segments and covered with a thin layer of chitin. Safe for fish, is an excellent food object.

Rotifer in the aquarium

Plankton, sizes from 0.03 mm to 0.2 mm. They got their name from the Slavic word “kolo”. the sun. The fact is that the rotifers’ mouth apparatus constantly rotates and is used not only as a mouth, but also as a motor. Harmless, filtering water, and along with brine shrimp are ideal food for fry of any fish from the first days of life.

= Uninvited guests in the aquarium or the identification of a krakozyabra! =

Every aquarist at least once in his life has come across a situation when uninvited inhabitants are found in his favorite aquarium, which the aquarist did not inhabit. It can be various snails, crustaceans, worms, coelenterates and other animals.

Let’s figure out how they get into the aquarium, is it worth any of them to be afraid, and what methods of dealing with them exist.

A postulate that I want to say right away, since it is true for almost all uninvited guests: if they began to actively reproduce. you are overfeeding the fish or simply haven’t cleaned the aquarium for a long time.

Also, before starting the identification of “aquarium reptiles”, it is worth mentioning the general scheme of how to deal with them and get rid of them. The first thing to do is to clean the aquarium: siphon the soil, wipe the walls of the aquarium, clean the filter. Then you should apply one or another remedy for the “parasite”, many of which do not tolerate any drugs, ie. you can pour in the same Tetra Contralk, if it is, and this will be enough for many simple organisms. But one should, nevertheless, understand the nature of the uninvited guest. If these are worms, then you need to use an anthelmintic drug, for example, often aquarists advise using the vet-pharmacy Febtal from planarians, and the pharmacy Nemozol 400ml also copes with these tasks. If it is a fungus, then you need a fungicidal agent, for example, Tetra FungiStop.

It should also be understood that most unidentified guests are safe for the aquarium and are an excellent food source for fish. Basic aquarium care can eliminate their numbers.

Now let’s get down to answering the question: what happened in the aquarium?!

How to get rid of hydra in an aquarium?

It all depends on the size of the hydra population, and the species composition of your tank. Gourami, as well as other labyrinths: cockerels, macropods, lalius eat hydras, and will cope with a small population on their own. If there are a lot of hydras, in our opinion, the best way out. resort to modern achievements in aquaristics, special drugs against hydras, such are in the product line of all well-known manufacturers of aquarium chemistry, most often such preparations are made on the basis of heavy metals, for example, copper, but many years of experience and numerous tests have allowed scientists to create drugs that can kill hydras and at the same time do not harm the fish.

There are other ways, one of them. add salt to the water, calculating the dose so that 0.5% saline solution is obtained in the aquarium. This inhibits the growth of the hydra population, do you remember what happens to various slugs if you sprinkle them with salt? But keep in mind, before using this method, you need to make sure that all other inhabitants of your aquarium tolerate a similar level of salinity.

And finally, 2 very extreme methods: temporarily relocate all the fish, and raise the temperature in the aquarium above 42 degrees Celsius for an hour, the hydra should die, but keep in mind that not all beneficial bacteria tolerate such a temperature, and such an aquarium bath, with very likely to hit the biological balance in it.

The latter method can be compared to nuclear bombing, and should be resorted to when absolutely nothing helps. this is a complete restart of the aquarium, with draining all the water, flushing the walls, boiling the soil and decorations and other horrors.

Aulophorus in the aquarium

Snail leech in the aquarium

It is similar to a planarian, but differs in a smaller size and a brown or brown color; the leech is introduced most often with soil. You can use salt to fight, but with great care, as salt can harm the snails themselves. Recipes for making baths vary, for example, there is such a place to place snails in 1 liter of water, after dissolving 2.5 teaspoons of salt in it. The bath lasts 10 minutes.

Application “Fish in the aquarium

On November 11, 2016 there was a lesson on the application “Fish in the aquarium”. The day before, the children looked at pictures of aquarium fish, studied the structure of the fish, playing with them the board game “Fishing”. We watched a slideshow of pictures with the image of fish.

We watched the multimedia presentation “Fish” about river and marine life, as well as “Aquarium fish”.

In the lesson, the children guessed the riddle about the fish; learned that an artificial underwater world for fish. an aquarium was created by human hands. Pinned the composition of the number 3 by counting out the handouts for the work. Cut out the fish using templates and yourself.

We had a physical education “Fish dance” and continued independent work. At the end of the lesson, we admired each other’s applications and designed an exhibition for parents.

Abstract for the application in the preparatory school group “Fish in the aquarium

Purpose: to form artistic and practical skills and abilities in children.

Preliminary work: reading works about sea and river inhabitants; viewing cards and illustrations depicting the inhabitants of rivers and seas, aquarium fish, a slideshow of samples of the application “Fishes in an aquarium”, examining toys-fish, board game “Fishing”

Materials and equipment: multimedia presentations “Fish”, “Aquarium fish”; application patterns; A4 paper of pale blue, pale green or lilac (optional) for an aquarium, paper of different colors and shades, scissors, glue.

  • Organizing time

Educator: Guys, we received a letter from Dunno. He writes that he was presented with an aquarium, but there is no one there. Who lives in the aquarium? Guess the riddle.

  • Where else can fish live? (The teacher shows the presentation “Fish”)

Educator: What is the difference between fish habitats: the underwater world and the aquarium? (lead children to the idea that the aquarium was created by human hands, that this is an artificial underwater world)

Educator: An aquarium is a whole underwater world at home. We cannot live without air, and fish cannot live without water. this is their home. At the bottom there can be many multi-colored pebbles, shells, and many more different plants. What are their names? (seaweed). Algae purifies the water in the aquarium.

Educator: Children, and what fish live in the aquarium?

Children are called. (The teacher shows the slides of the presentation “Aquarium fish”).

  • Educator: Guys, only 3 fish can fit in Dunno’s aquarium. And how many units does the number 3 consist of? How to make the number 3 from two numbers?

Children lay out handouts and repeat the composition of number 3.

  • Performing the work “Fish in the aquarium”
  • Physical education “Fish dance”
  • Performing the work “Fish in the aquarium”

Each of you can learn a lot of interesting things about fish and sea animals from encyclopedias and different books.

Life Span of Aquarium Fishes

What breeds of fish do they get along with?

There is a table that contains the most popular types of aquarium fish and shows the degree of their compatibility. The sign “” means that the fish are compatible, the sign “-” means the absolute incompatibility of the species, and the sign “0” indicates that it is possible to combine, but with some reservations.

According to the data in the table, our “watchdogs” will get along well with swordsmen, labeos, irises, plekostomuses, rasbora, platies, bocias, gourami, zebrafish, corridors and scalars.

The best neighbors for them will be swordtails, which are not inferior to barbs either in activity or in aggressiveness. Gourami and thorns are quite nimble, they can fight back, so they will get along quite easily in the same aquarium with barbs.

Mollies and barbs, as a rule, do not notice each other, which means that they may well exist together.

The Sumatran barb will get along well with the zebrafish. The latter are not shy, not particularly capricious and quite active. In addition, zebrafish, with their bright transverse stripes, go well with the color of Sumatran barbs.

Catfish are another species that will get along well with barbs. In a catfish aquarium, the lower layers of water are favorite places, while nimble barbs prefer to swim higher. Ancistrus, as a representative of the chain-mail catfish family, will feel great in the same aquarium with barbs. They are quite peaceful and prefer to hide under artificial shelters most of the time, rather than engage in battles with other inhabitants.

Factors affecting compatibility

When populating an aquarium with fish of various species, you need to take into account the factors of their compatibility. These factors primarily include the degree of aggressiveness and territoriality of certain species.

Barbs, as already noted, the fish are active and frisky, in some cases even aggressive, so a spacious and preferably rectangular aquarium will be the best option for them.

The more free space, the lower the likelihood of fights between barbs and other species for the territory.

These fish are big badass, so very often other inhabitants of the aquarium living nearby hide from them. In order for them to have somewhere to hide in the aquarium from fidget barbs, it is necessary to purchase green plants and artificial shelters. The denser the thickets in the aquarium, the more intact other types of fish will be.

In addition to those named above, other factors of the coexistence of different fish in the same aquarium are of no small importance. For example, it is very important for our “heroes” to live in a pack. To distract the attention of barbs from other types of fish, it is better to purchase not one, but two or even three varieties of these fidgets. So they will take care of each other and pay less attention to quieter neighbors.

In addition, under no circumstances should you settle viviparous fish in the same aquarium with barbs. For predators of barbs, fry are a delicacy, so they will not calm down until they have exterminated everyone.

READ  How long should a compressor run in an aquarium

Such a factor as the habitat layers of different species can help place even such fish that, it would seem, absolutely cannot live together. And all this is possible only because fish that prefer to spend time in the bottom layers are unlikely to be able to intersect with surface species.

And, of course, one of the basic rules is a sufficient amount of food. A deficiency can lead to fights. The feed should be varied and in sufficient quantity. It is best to feed the nimble fish of the described species with bloodworms, tubifex, cyclops and daphnia.

Compatibility of barbs with other fish

It is absolutely certain that most people have thought about purchasing an aquarium with fish at least once in their life. After all, an aquarium with colorful fish swimming in it is not only very beautiful in terms of design, but also incredibly interesting in terms of acquiring new knowledge and skills. Beginner aquarists do not acquire fish breeding skills immediately, so they try to start at first unpretentious fish to care for, for example, barbs.

With whom cohabitation is possible, but not very desirable?

It is possible to settle with some types of barbs, but nevertheless their neighborhood can hardly be called desirable, because you will have to comply with some rules of residence, which is not always possible to do.

For barbs, not very good neighbors are: cichlids, discus, loaches, guppies and shrimps.

For rather large and aggressive cichlids, it is important that the territory in which they live belongs only to them, so restless barbs for them are not the best option for neighborhood.

You can keep barbs with cichlids, but on condition that the cichlids are young and the barbs are adults. But when the first ones grow up, they will have to be planted, otherwise there will be no barbs left in the aquarium.

Compatibility with guppies is possible provided that both fish are planted in the aquarium at a young age. But at the same time, it must be remembered that barbs can turn beautiful guppy fins into a kind of ragged rag, so living together is also not a good idea.

Ampularia and shrimps are rather phlegmatic inhabitants of the aquarium, so living together with cocky barbs is highly undesirable for them. There is a high probability that the tendrils of the ampularia will be gnawed, and the shrimp will simply disappear.

Features of the character of barbs

These fish are quite attractive in appearance. According to the scientific classification, they belong to the carp family. Under natural conditions, these representatives of the aquatic fauna live in fresh water bodies, are rather large in size. Their homeland is Africa, India, China and Indonesia. Aquarium varieties of barbs are very small in size, the average is within 5-8 cm, and in the largest individuals. no more than 12 cm.

Barbs are nimble and curious fish, they swim in the aquarium rather quickly and like to “explore” the corners and cracks hidden from human eyes. For their activity, they are often called watchdogs, since their behavior is somewhat reminiscent of the behavior of dogs, not fish. They are not only unpretentious in terms of water purity, but also not very capricious in terms of the type of feed.

Keeping these fish is easy, the main thing is to take into account their active behavior. And since they are schooling fish, it is best for them to be surrounded by individuals of their own species. To suppress their sometimes excessively aggressive behavior, 7-8 fish in the aquarium are enough. so they will bother less “neighbors”, and more engaged in sorting out the relationship between themselves. It is not worth keeping more than 8 individuals in the aquarium, because they will begin to bully other inhabitants of the aquarium and, with great persistence, win back space for themselves.

Their aggressiveness is in direct proportion to belonging to one of the varieties. Before purchasing these nimble fish, it is worthwhile to understand in more detail the aquarium species.

  • The most cocky and pugnacious are the fish belonging to the Sumatran species. They are characterized by an average size of no more than 5-7 cm and a rather bright color. The body of the fish is literally all “lined” with black wide vertical stripes, perfectly combined with the main golden background. There are individuals with four and five stripes.
  • The fire barb differs from the Sumatran one in color, body structure, and behavior. Representatives of this variety do not grow in an aquarium more than 8 cm, they have a more peaceful disposition.
  • The black variety is one of the most popular fish and therefore has almost every aquarist. The body shape of a typical representative has similar outlines to the Sumatran barbus, but the color is completely different. Although stripes are present, they are not as pronounced as in Sumatran individuals. In addition, the brightness of the stripes depends on the conditions. The more green plants in the aquarium, the brighter they are.
  • Linear barbus is distinguished by its peaceful character and bright colors. In typical representatives, the basic tone is golden yellow. Individuals of this species can grow up to 8-10 cm in length. Males are smaller and brighter than females.
  • The clown barbus (everett) is a very active, agile and jumpy fish, but with a peaceful character. Feels comfortable in a group of 6-7 individuals who like to stay in the lower layers of the aquarium.
  • The mutant barbus is a rather rare and valuable fish of one of the forms of the Sumatran variety. Has an unusual and interesting character. Very mobile and playful, generally peaceful. Their aggressive nature manifests itself in those cases if they suddenly remain alone. without a pack. In a flock, these individuals do not terrorize other representatives of the aquarium. Most active during the day.

With whom joint is contraindicated?

They do not get along at all in the same aquarium with barbs: veil-tails, goldfish, neons and astronotuses.

Veil-tails have very beautiful and bright fins that will undoubtedly attract the attention of the ubiquitous barbs. Calm veil-tails are unlikely to be able to dodge them, so the fins will be bitten off rather quickly. In addition, the temperature regime for veil-tails is somewhat different. they prefer cooler water than barbs.

Neons are delicate, sensitive and poorly tolerant of stressful situations fish, so cocky barbs are not at all suitable for them as neighbors.

With astronotuses, barbs cannot be planted for quite the opposite reason.

Astronotuses are predators, and they are quite impressive in size.

Little barbs cannot overcome them, and they will not be able to hide, since astronotuses will find them everywhere. Most likely, after a very short period of time, there will be no trace of the flock of our fidgets.

You will learn more about the care and maintenance of barbaruses from the video.

Interesting Facts

Some interesting facts about fish, fish and sleep:

    Parrotfish have “nightwear”. before going to bed, they create a cocoon of mucus around themselves.

It is believed that such a bubble is designed to protect them from predators: it masks the smell, and in the event of an attack, it gives the victim time to wake up and react.
Sharks do not have an air bubble, so they adapt in different ways to be able to sleep. So the shark Katran sleeps on the move. the spinal cord is responsible for the movement.

Other sharks constantly open and close their mouths while resting, ensuring the movement of water near the gills.

  • If the fish cannot sleep, then it tries to make up for rest as soon as possible.
  • When fish are under stress, they can suffer from insomnia.
  • Influence on compatibility of different species

    After studying the behavior of aquarium fish, scientists divided them into 2 categories:

    • crepuscular. those who see well in the dark, therefore they hunt at night and rest during the day;
    • light-loving. those who are active during the day.

    The first category is mainly represented by predators. When selecting fish for an aquarium, it is important to know what type they belong to, because the neighbors of representatives of groups should not be allowed.

    • incompatibility of characters. predators will simply begin to feed on ornamental fish;
    • the fact that it is uncomfortable for crepuscular fish to be in bright lighting, which is necessary for light-loving;
    • a mismatch between sleep and rest, which will provoke illness. the inhabitants of the aquarium will constantly interfere with each other.

    Photo of what sleeping individuals look like

    Sleeping fish are difficult to recognize due to the fact that they do not close their eyes. This is due to the absence of eyelids, which they simply do not need. water already cleans the surface of the eyes.

    From the outside, it looks as if the fish just drift in the water column and barely noticeably wiggle their fins and tails. But as soon as you make a sudden movement or turn on the light, the activity in the aquarium will instantly resume.

    In the photo you can see how the fish sleep:

    Dream of fish night and day

    The dream of fish is significantly different from that of humans. The reason for this is the peculiarities of the habitat: fish cannot afford to disconnect from the surrounding reality. it is important to quickly respond to an approaching danger or prey.

    Therefore, they never fall into a state of deep sleep. the brains of animals are constantly working. This is due to the alternating activity of its hemispheres, which allows the fish to remain conscious.

    They do not necessarily sleep at night, it all depends on the type and characteristics of its life: some fish are active in the daytime, others in the dark.

    Therefore, it is important to create appropriate conditions for them:

    • provide a place to hide;
    • choose the right neighbors so that their modes coincide;
    • always turn off the lights at night.

    In addition, fish, like people, do not like it when they disturb their peace of mind.

    Do fish sleep in an aquarium and how can this be understood?

    It seems that the fish in the aquarium never sleep or even rest: they are constantly in motion. But no living organism can exist without sleep.

    READ  Is it possible to turn off the filter in the aquarium

    However, fish sleep has its own characteristics, knowing which it will be easier not only to equip an aquarium and pick up neighbors, but also to provide pets with maximum comfort.

    We will tell you about how fish sleep in an aquarium and how to understand that an aquarium inhabitant is asleep in the article.

    Is there hibernation or hibernation?

    Sometimes some fish species can go into a state similar to hibernation. the same sleep, but longer (up to several months) and deeper.

    At this time, all physical processes in their body slow down greatly, and the aquatic inhabitants themselves freeze in the water column or settle at the bottom.

    For example, in Africa, a species of fish was discovered that can form a mud cocoon around itself and hide in it for several months. The inhabitants of aquariums do not have such a need, but in case of a threat to their lives, they are also able to fall asleep for a long time.

    Hibernation is more typical for the inhabitants of natural reservoirs. When cold weather sets in, fish hide in secluded places or go to the depths. Then they create a cocoon of mucus around themselves to protect against microbes and predators, after which they fall asleep for the whole winter.

    Where do they do it?

    The inhabitants of the aquarium sleep in different ways, but there is one thing in common. their activity becomes minimal. Some fish simply “hang” in the water, others cling to leaves or branches of plants.

    There are those who sit comfortably on their side or abdomen, sinking to the bottom. There are also those who like to sleep belly up, freezing upside down and even burying themselves in the sand.

    This mainly depends on the presence of a swim bladder, that is, the organ that contains air and allows fish to rise to the surface of the water, be in its thickness, or sink to the bottom. So the inhabitants of the aquarium have the opportunity to stay at a certain depth during sleep.

    However, not all fish have a swim bladder, which means that they need to be constantly in motion in order not to lie on the bottom. It would seem that it would be a good option, but the gills of such individuals are designed in such a way that they can receive oxygen only by moving.

    Therefore, fish are forced to move even in their sleep or find places with a bottom current, which will self-wash their gills. Among the aquarium fish, there are few of them. botsy, ancistrus and catfish.

    “Hanging” the fish in a strange position may be associated not only with sleep, but also with illness. Therefore, when this behavior is observed in a pet for the first time, it is better to knock on the glass next to it and observe the reaction. If he returns to his usual activities, everything is fine.

    Types of aquarium snails

    Despite all the disadvantages, mollusks are kept in the reservoir as orderlies. For example, useful snails for an aquarium are ampullia, they are bred specifically to maintain cleanliness. They penetrate into hard-to-reach places and remove algae growths, pick up food that has not been eaten. There are a variety of snails in the aquarium, their species differ in shape, size, color, most of them are harmless. The design of the reservoir becomes more interesting if such inhabitants are present in it.

    Helena snails in the aquarium

    Helena aquarium snails. a predatory species, they feed on their relatives, have a ribbed shell, conical, without a tip. The color of the carapace is yellow with spiral stripes of a dark brown tone. The size of the mollusk is 15-20 mm, its body is gray-green. Helena buries herself in the ground, she needs soft sand or gravel. At home, it does not multiply much. Her diet is carrion and small snails. These are popular predator species, they help fight the growth of the population of other mollusks in the reservoir. But Helena cannot cope with large relatives.

    Snails in the aquarium. species, useful tips for keeping shellfish

    Molluscs play an important role in the home pond. A wide variety of snails in the aquarium, the species of which are numbered in dozens, are popular among amateurs. They fall into the water from everywhere. the brought plant may contain caviar, but some aquarists buy deliberately. The presence of molluscs is permissible in any vessels, except for spawning.

    Aquarium snails. and care

    Snails are indicators of oxygen in the environment; when there is a lack of oxygen, they go upstairs to take a breath of fresh air.
