Fish That Inflates Like A Ball With Spikes

Puffer aquarium ball fish also swell with air when handled. And then they swim belly up for a while, until they “blow away”. They look the same as ballrooms in nature, only the size is slightly smaller.

Fish That Inflates Like A Ball With Spikes

The ball fish should be kept in a large, spacious aquarium of 150-160 liters, where various driftwood, grottoes, floating and growing plants are needed. And leave room for free swimming. They can gnaw plants, but they will not eat.

From food they prefer worms, sedentary fish and their fry, of course, snails. It is better to pick up neighbors large and mobile, because this fish is a predator and will simply eat small ones.

In dangerous moments

What is the name of the fish that inflates like a ball and why? This question can be asked to schoolchildren, and many will give the correct answer. When she feels danger, she begins to swallow water very quickly and swell in the form of a ball. This shows that she is too big to eat.

When swallowed, the liquid enters a special inflating bag. And the fish breathes with gills and much faster than before the adoption of a round state. This suggests that they expend a lot of energy. Because of this ability, these fish have another name. sharotel.

What does a ball fish (puffer) look like? Photos and interesting facts

At the moment of danger, the fish-ball swells so much that it seems to burst at any moment. But in general, why such transformations occur with the fish will be told by “I and the World”.

Funny creatures

The description of these fish is very interesting. The eyes are surprisingly mobile and expressive. And the fish move like bees, quickly waving their wings in one place. And sometimes soaring up like a colorful airship. The ability to hover in place and move backward is due to the pectoral fins. Females are usually larger than males and slightly paler.

The “transformation” into a ball is facilitated by the unusual structure of the body, which does not have a bone shell, and the presence of thorns-needles. This is what can happen to a predator if it does swallow a fish ball (see photo).

Some of the ball casters have very small thorns, some are rather long and sharp. For example, a hedgehog fish with thorny spines looks very frightening. Look at pictures of “round” fish.

The barbed fish is very fond of snails, which are captured with their mouths with crushing plates. They quite quickly approach the victim and grab.

These fish are really dangerous to humans. Their muscles contain the deadly poison “fugu”, so fish meat cannot be eaten even in a highly cooked form. Even the smallest piece is poisonous, acting on the heart and nerve centers.

In Hawaii, the aborigines smeared arrowheads in the bile of sea fish, calling, at the same time, a death fish. Haitian shamans made a mixture of fish, turning people into zombies, thanks to tetrodotoxin, which suppresses the activity of the nervous system.

About aquarium ball fish

The appearance and behavior of the aquarium ball fish will leave few people indifferent. The ability to swell in moments of danger brought her such a name, and an interesting disposition. the love of aquarists around the world. However, this exotic predator needs a special approach. She will not be able to live without constant care from the owner. To create a comfortable environment for your fish in the aquarium, you need to get to know their habits and needs as much as possible.

Conditions in the aquarium

To keep one individual, a container with a volume of 50 liters is sufficient. For a couple, respectively, 100 liters. Ball fish like to be in the lower layers of water all the time. Take care of hiding places in the aquarium and plants with hard leaves. These fish need shade.

The water temperature in the aquarium should be kept within 25-28 degrees. Need aeration. You also need to purchase a special pump that will filter the liquid. Once a week, you need to fill the aquarium with fresh water (30% of the volume). Remember that a clean aquarium is the key to the health of all types of fish.

The ball fish is a loner, they are kept in pairs in aquariums for breeding. Can be kept in aquariums with non-aggressive neighbors.

When it comes to nutrition, aquarium tetraodons are predators. They only recognize live food. Favorite menu:

  • Worms;
  • Bloodworm;
  • Tuber;
  • Fish fry.

At home, care must be taken so that the fish can grind off sharp dental plates. To do this, snails are introduced into the diet.

What makes a hedgehog fish different

This is a subspecies of ball fish. Real hedgehog fish belong to the pufferfish, the scientific name is Diodon. These are poisonous predators with sharp needles. Skin and liver are especially poisonous. They contain tetrodotoxin, which causes paralysis of the respiratory muscles. In no case should you touch the blowfish with your bare hands (only with special gloves). The thorns are also saturated with poison. Even micro doses are fatal to humans.

The body of the fish is covered with many specks. The head is rounded, with strong jaws. It looks like a bird’s beak. The eyes are set wide apart. Instead of teeth, special sharp plates. When the hedgehog fish is calm, the spines are pressed to the body. Under stress, swells up and becomes 4 times its original size.

Tetraodon habitat

These fish are considered the most poisonous representatives of the marine fauna. Most often, such individuals are found on the coasts of Indonesia, the Philippines, Ceylon, India, as well as the Malay Archipelago. They also live in large rivers in Africa and South America. Ball fish like places with coral or dense vegetation (it will become a reliable shelter). If there is somewhere to hide, then they are less aggressive. The rhythm of life depends on the sun: fish wake up at sunrise and go to rest at sunset.

Different names. one fish

Aquarists are looking for unusual creatures for private collections. And it is the ball fish that often becomes the highlight of the home aquarium.

This fish has many names. As soon as they call it: and sharotel, and tetraodon, and fish-dog. It can often be found under the name hedgehog fish. The famous fugu made by Japanese masters is also our beauty.

Different types of fish prefer fresh or brackish water for habitation. Tetraodons phagak, mbu, miurus are considered freshwater.

Lightly salted water is preferred by tetraodons such as figure eight and green.

Propagating domestic tetraodons

Spawning in an aquarium for each species takes place individually. The only condition is a separate aquarium. Young fish are calm and non-aggressive. It is difficult to distinguish them by sex. Male representatives are smaller and dull in color. Exercise extreme caution during spawning.

The male gently pushes the female towards the upper layer of water. Here she spawns. The male immediately fertilizes the eggs. After a couple of days, you can see yellow-red fry with an already formed muzzle and the beginnings of fins. After a week and a half, the kids become independent swimmers. The favorite place of fish in the aquarium is dense thickets of plants.

Description and features

The appearance of these fish is very different from other species. They have a short, elliptical body. All members of the breed have bulging eyes. The branchial slits consist of two openings. Since the ball fish belongs to predators, it has a special structure of the mouth. The cavity contains four plates that help crush food. With the help of fins, these fish carry out different maneuvers: they move backward, easily change directions and hang in one place. The main protective function is performed by special spikes that replace traditional fish scales.

The ability to puff up is another striking feature of the fish. It’s all about the elastic stomach. At the slightest danger, the fish draws water into it. This makes her body round like a ball. There is also gas in the stomach. What about breathing? Scientists put forward two versions: on one, the fish continues to breathe through the gills, and on the other. it is forced to hold its breath. Australian experts experimentally proved the first version.

The scientists also noted that the respiratory rate increases 5 times compared to the resting period. This is a colossal energy expenditure for fish. It takes several hours for breathing to return to normal.

Behavior and nutrition

In their natural environment, they can be found in ocean waters near the tropics. Many hedgehog fish are found off the coast of Japan and on the Russky Island. They feed on shellfish, sea worms, oysters and corals. Solid lime remains of the shells are deposited in the stomach in the form of a powder, then excreted from the body. Dry food should not be given in an aquarium.

Habitat

They are natives of the coast of India, the Malay Archipelago, Indonesia, the Philippines, the Amazon basin, the lower reaches of the Congo River and some rivers of southern Primorye of Russia. Off the coast of Japan, fugu live mainly in the seas of Yamaguchi Prefecture.

Social structure and reproduction

Due to its isolation, the tetraodon rarely forms strong social ties, preferring a hermit life to accuracy. The most acceptable social device for puffers is small schools or couples. In youth, representatives of the species are relatively calm, but the older they get, the more their character deteriorates and the more they are subject to aggression.

Representatives of the species are ready to reproduce at the age of one to three years. During the spawning period, males and females perform the following mating ritual: the male playfully pursues the female, and if she does not agree with his courtship for too long, he may even bite. The males, often having a flashy coloring and smaller size, delicately escort the female to a secluded, protected place. There she lays eggs, and the male immediately fertilizes her. Some puffer species prefer to spawn in the upper waters. A female can lay up to five hundred eggs once.

In the first weeks of life, all subspecies of blowfish have a small shell, which gradually disappears, and thorns form in its place. The ball fish quickly forms, and after a month it differs from older individuals only in smaller size and color intensity: in young fish it is much more variegated. With the help of bright colors, the younger generation tries to prevent a potential threat and scare predators. In order to protect themselves, young animals also like to hide in safe hidden places: in thickets or bottom relief.

Young individuals are the most contact. They can safely cohabit with different species without harming anyone. The quarrelsome nature begins to manifest itself in puffers only with age. Divers need to know that it is not recommended to keep more than one male in the aquarium during the spawning period in captivity for the successful reproduction of the species. Due to their aggressive nature, the rivalry will quickly turn into a fight, which will definitely end in death for one of the males.

Fish ball

The unique defense mechanism of the ball fish that has made it so interesting to humans is its ability to inflate its body. Gathering water or air into the saccular outgrowths, acting as a kind of pump by the gills, the blowfish can increase several times. Due to the absence of ribs, this process is controlled by special muscles, which subsequently help the fish get rid of the accumulated fluid or air, releasing them through the mouth and gills.

The most effective method of protecting the puffer is its toxicity. The skin, muscles and liver of most species are saturated with the deadly poison tetrodotoxin, which, when it enters the digestive tract, first paralyzes the victim, and then painfully kills. It is surprising that a man chose one of the representatives of blowfish. puffer fish. as his delicacy. At least one hundred people die every year as a result of eating it. However, not all tetraodon species are poisonous, and some are even safe to keep in your home aquarium.

Appearance and features

Due to the wide variety of subspecies, ball fish can look very different, but have some common interspecific features:

So, in length it can reach from 5 to 67 cm, depending on the environment in which it lives. The color scheme of tetraodons, as a rule, varies from white-brown to green, but the characteristic color of each species is different, and the individuals are individual.

The body of the blowfish is plump, ovoid, with a large head and wide-set eyes. One of its names. puffer. the ball fish owes four massive teeth that have grown together into the upper and lower plates, thanks to which the individual becomes a dangerous predator and is forced to constantly eat coral reefs or inhabitants with a chitinous shell.

One of the unique features of the tetraodon is its uncharacteristic skin for fish, covered with small spines, rather than scales. At the moment of danger, when the fish swells, these spines provide additional protection. they take an upright position and do not allow the predator to swallow the blowfish.

Origin of the species and description

Tetraodons, members of the blowfish family, were first described by Carl Linnaeus in 1758. Scientists find it difficult to determine the exact age of the puffer, but they agree that several centuries ago this species separated from another, called the sun fish.

To date, science has more than a hundred species of these fish, mainly living in the tropical salt waters of the Pacific, Indian and Atlantic oceans. Some species of ball fish prefer to settle and breed in fresh waters. However, for a comfortable habitation of all subspecies of tetraodons, seclusion is necessary: ​​they like to settle among corals or dense vegetation, and often prefer solitude or life in a small school.

Where does the ball fish live??

Ubiquitous, tetraodons like to settle in coastal waters and are rarely found at depth. Most often they can be found in the tropical waters of the Philippines and Indonesia, India and Malaysia. Almost a third of the pufferfish are freshwater inhabitants, including the fahak, which lives mainly along the Nile; mbu, who prefers the waters of the Congo River; and the famous takifugu or brown puffer, lives both in the Pacific Ocean and in the fresh waters of China.

Some subspecies lead the following way of life: living in salt waters, during the spawning period or in search of food, they come to fresh or brackish springs. Having spread in this way around the globe, ball fish feel comfortable in almost any habitat, except for captivity, they are difficult to breed and require careful and special care in aquarium conditions.

Features of character and lifestyle

The aggressive social behavior of puffers has earned them the fame of loners. Often anticipating danger, and having trouble-free defense mechanisms, blowfish swell and thus frighten their enemy. However, the constant use of this skill does not benefit its owners. The respiration of an individual during metamorphosis accelerates five times, which indicates an incredible increase in heart rate. Therefore, although constantly ready to attack, the ball fish is prone to a solitary lifestyle.

Ball fish love to defend their territory and do not forgive the encroachments of the enemy, desperately defending themselves. In a fight, blowfish mutilate and bite other fish fins, doing this as part of the struggle for territory, and sometimes out of a sense of rivalry.

Ball fish, regardless of their species, adhere to the correct daily routine: they wake up with the sunrise, fall asleep at sunset. During the day they lead an active hunting life. This is one of the reasons why those wishing to have a ball fish in their home aquarium are not advised to live in the wrong company. The blowfish will either eat all the inhabitants, or consider them sources of stress and, due to excessive nervous stress, will quickly die. In captivity, tetraodons live 5-10 years, while in their natural habitat. much longer.

Natural enemies fish ball

Due to the unique defense mechanism, aggressive nature and craving for a secretive lifestyle, blowfish have practically no natural enemies. However, they did not escape the fate of being an element of the nutritional chain due to the omnivorous nature of the main predator. man.

Widely known around the world for its poisonous properties, ball fish, however, are one of the main delicacies of Japanese cuisine. Regardless of the number of deaths that these fish bring to people every year, gourmets continue to eat them.

In Japan, there is a special license issued to chefs who are trained to cook this deadly dish. As you know, the use of fugu liver and ovaries, as containing the most concentrated poison, is prohibited. To date, there is no antidote for the poison, and the victims are assisted in maintaining the circulatory and respiratory systems until the effects of the poison weaken.

Fish ball

Drawn by the secrets of the ocean depths, people have long sought to get to know its inhabitants better. In the richest aquatic world, which gave birth to all species known to us, you can also find such an amazing creature as a ball fish, also known as a blowfish, puffer or tetraodon.

READ  How Often Should You Feed The Fish In The Aquarium

These amazing fish got this name because of the special structure of their body: at the moment of danger, they inflate like a ball and thus scare off the enemy. Thanks to this spectacular defense mechanism, tetraodons are ubiquitous.

What does a ball fish eat?

Puffers are confident predators. Completely ignoring algae as a food product, tetraodons are happy to eat food rich in protein: worms, fish fry and shellfish, snails and shrimps. Gluttonous by nature, ball fish do not give up their habits either in their natural habitat, not in captivity, they are able to absorb food constantly.

It is interesting that the plates, replacing the tetraodons with the tooth, grow in them throughout their life. Nature knows several examples of such regeneration, and everywhere it is solved in one way: the individual grinds off growing teeth. Skalozub for these purposes consumes a large number of crustaceans with a hard shell and gnaws at corals.

Habitat

The ball fish is found in the Indian and Atlantic oceans. The sea urchin can be found in the waters of Japan. The most popular type is called “Diodon long-spined”. It lives in its natural environment and takes root in aquariums. A distinctive feature of the predator is dark brown spots on the back. His fins are yellowish, without spots, the belly is light, the tail has no spines.
A predator living in natural conditions grows to 45 cm. Aquarists breed individuals 14. 16 cm in size. The needles of a fish that inflates in danger are long, but they do not contain poison. The insides contain a large amount of toxins. Under natural conditions, thorn fish live 18. 25 years, in an aquarium. up to 6 years.

Diodon ordinary is distinguished by its impressive dimensions, therefore it is rarely bred at home. The maximum size of the body is 90 cm with a weight of 3 kg. In the wild, individuals not exceeding 40 cm long are common. Diodon vulgaris is confused with representatives of the Long-spined family, but it has distinctive features. The body of the common Diodon is gray-brown with numerous small spots. The insides of marine life also contain poisons.

Lifestyle

The predator cannot be called a civilian. He behaves quite aggressively. To prevent the hedgehog fish from eating other inhabitants of the aquarium, you need to place it with relatives.

Blowfish prefer to hide in the shade. They are active in the evening and at night. The hedgehog fish often hides in algae. If there are caves in the aquarium, she swims in them.

The tetradon becomes ready to breed when it is 1 year old. It is better not to place 2 males in one mini-pond, as a fight over territory will begin. For reproduction to be successful, it is necessary to plant algae, hornwort or cryptocoryne. To stimulate spawning, Pufferfish are fed with snails and meat. Individuals reproduce at a temperature of 28 degrees.

A hedgehog fish should be placed in an aquarium with congeners, as it can eat other fish

It is important to know how to distinguish a female from a male tetradon. The female is larger, has pronounced spots on the body. At the beginning of spawning, the male chases the female. If she does not behave aggressively, the couple swims to the bottom and hides behind dense algae.

At home

One predator does well in a 50 L tank. If you plan to breed 3 individuals (one male and two females), you must rely on a capacity of 150 liters. For 5 adult fish a 250 l aquarium is required.

A 50 liter aquarium is suitable for a hedgehog fish

Sexually mature tetradon reaches a size of 15 cm. In order for it to develop favorably in the aquarium, you need to regularly change the water. Aeration is recommended. The predator prefers salted water. Salt is added at the rate of 15 g per 20 l. If the puffer fish is in fresh water, it can get sick.

Puffer fish, which swell in danger, live at the bottom of the mini-reservoir. Algae, medium-sized stones can be placed in the aquarium. The hedgehog fish often hides in the shade. In order for it to retain its natural color and not suffer from oxygen deficiency, the temperature regime must be observed. The predator takes root in water with a temperature of 28 degrees. Change 10% of the water every day. If other types of fish prefer fresh, they should be placed in a separate container.

The blowfish eats food of animal origin. He positively perceives:

  • Shellfish;
  • Malkov;
  • Worms;
  • Snails;
  • Crushed crayfish;
  • Beef meat and liver.

Puffy fish do not eat plant foods. Do not give her dry and frozen food. If a predator has weak immunity, it can die from such nutrition.

Pufferfish eats only animal food

Tetradon fry feed on ciliates, egg yolk. If cubs live in a mini-reservoir, it is worth placing river sand on the bottom. The fry grind their teeth on him. A fish that inflates like a balloon gets along with an African cichlid, but individuals must be the same age.

Predators cannot be kept in the same aquarium with fish that have beautiful long tails. Adult predators are very aggressive, biting fragile creatures. If you need to deal with snails, which are very actively multiplying, you should place one Blowfish in the reservoir. He eats shellfish in a week.

Fish that inflates like a ball (thorn fish)

The hedgehog fish is often compared to the puffer: both predators are poisonous, have a similar physique and belong to the Pufferfish genus. Fugu is distinguished by thorns, sea urchin. by needles. When the puffer senses danger, it grows in size, and so does the sea urchin. Fish that puff up behave in much the same way. At home, they often contain a sea urchin.

Fish hedgehog is poisonous and swells in case of danger

Description and types of sea urchin

The fish has special bags. She fills them with air or water. The ability to swell is due to anatomical features. When the marine life grows in size, it becomes like a ball with spines. Some species of Blowfish retract the anal and dorsal fins. When a fish swells, it feels life threatening.

The Blowfish family has more than 16 species. Aquarists and just fish lovers should know how to distinguish a hedgehog fish from a puffer:

  • The first has a large mouth, it is somewhat reminiscent of a bird’s beak. On the upper and lower jaws, there is one cutting plate. The peculiarity of the fugu is that it has two plates on the jaws. They merge into a single whole, as they are connected by a seam.
  • The hedgehog’s needles are long and fit tightly to the body. There are thorns on the body of the fugu.

Breeding Puffer Fry

The female produces 200. 300 eggs. She has no maternal instinct, but the male protects the eggs. After spawning, it is recommended to place the mother in a separate container. If the caviar acquires a milky color, then it is adapting to new conditions. The fry are fed with grated egg yolk. Crayfish are included in the diet as they get older.

Now aquarists have received an answer to the question of what is the name of the fish that inflates like a balloon. Of interest are 2 species: puffer and sea urchin. The puffer fish does not make high demands on living conditions, but aeration must be in the aquarium. Fish-hedgehogs are active and pleasing to the eye for many years.
