Puffer Fish – a complete description of the marine life

Iglobryuhovyh called the family of fish, in which there are 29 genera, 200 species of individuals. Their distinguishing features are the presence of sharp teeth, toxicity, the ability to quickly change the shape of the body.

Due to the unique characteristics, puffer fish began to be called fish dogs, puffers, chetyrezyubs (Latin Tetraodontidae). The most famous representatives of the family are the Fugu fish, hedgehog, and star-shaped puffer (Arothron stellatus).

The latter is impressive in size and can reach 120 cm in length. As an exotic pet, you can keep small individuals of tetradons: green and reddish puffer, and kutkutyu.

Puffer – real decoration of the aquarium

Externally, puffers are the sweetest creatures. Novice aquarists are most attracted to their “smart” eyes with bright iris.

Fish show affection to the host and, demanding food, can in every way attract attention, cutting off teeth.

The size depends on the type and ranges from 6-110 cm.

The teeth of the fish rather resemble the bird’s beak. It helps to obtain food, splitting hard shells, shells of crustaceans.

The body of the puffer is short. The skin may be smooth or in small spiky growths that are tightly pressed against the body.

The fish has no pelvic fins, but there are pectoral ones. They are well developed and allow you to swim in any direction.

The tail plays the role of “steering” and does not participate in the acceleration of movement.

The stomach has a special structure. It resembles the collected harmonica furs. When a danger arises, the puffer breeze seizes water or air, and the folds of the stomach open up, becoming 100 times more than normal volume.

Rapid air intake is provided by the muscles in the mouth that act like a pump. Surprisingly, the frightened pufferfish will not force anything to release the contents of the stomach until it feels the danger has disappeared.

Even if a person becomes feet on a large individual, the fish will remain inflated.

Toothfish have a special structure of the skin, caused by the need to turn into a “ball.” It consists of 2 layers. Internal – more durable, providing elasticity, and the second – vernal, very elastic.

In ancient Egypt (27th century BC), the skin of a pufferfish was used to make durable balls.

When the puffer fish feels in danger, it inflates like a ball.

In the miracle fish there are no gill covers, ribs, because it makes it difficult to “swell up”. The powerful muscles of the peritoneum help to keep the shape.

At this, the differences from other species are not over. The puffers have tiny tentacles under their eyes.

They play the role of organs of smell. Puffer – a real fish-dog with the scent of a snooper, but not on land, but on the seabed.

Puffers are found in the Indian Ocean off the Southern coast of Africa and near Madagascar, in the Bay of Bengal off the coast of India, Malaysia and Thailand, in the Sea of ​​Japan and East China, off the coast of Australia, Papua New Guinea.

Among the tobies distinguish between freshwater and saltwater; as small as red or green Tetraodon, or as large as a star-shaped puffer; peace loving or aggressive.

Those who wish to acquire an exotic fish, it is recommended to pay attention to the types:

  • Tetraodon fluviatilis (green puffer). It has a beautiful yellow color with a tinge of green; its sides and back are decorated with large black spots. Like all puffers, it is thermophilic (it lives in water 24-27˚С). The size of an adult individual is up to 10 cm. The peculiarity of small fish is increased aggressiveness, skin tarnishing as they grow older.

In greenhouses, green puffers are most often bred.

  • Tetraodon miurus (reddish puffer) – is red, orange, has dark spots on the skin. This species lives in fresh hard water and grows up to 15 cm.
  • Canthigaster valentini (black-striped) – is distinguished by the presence of not only spots, but also several dark stripes on the back, with a bright yellow tail. He is moderately aggressive, can get along with other fish that can not be offended. Like other species, loves warm (up to 27 ° C) water.

One of the brightest representatives of the species is the star-shaped puffer. The size of the fish is 60 cm, the maximum is 120 cm. The star-shaped puffer is yellow, brown, orange, and the whole is covered with small needle-shaped processes.

The most poisonous puffer puffer are considered. Another name is “fish-death”, because in 60% of cases of poisoning the victim died.

According to gourmets, the taste of a dangerous delicacy cannot be compared with anything. After trying fugu 1 time, there is an overwhelming desire to try it again and again. The cost of meals varies from 500-1000 at. e. Cutting is trusted only to licensed cooks.

To get it, those who wish to attend are given special courses, at the end of which an exam is waiting for them: to cut fugu and cook sashimi. If you make a mistake, you need to wait 2 years to retake the exam.

Eating representatives of puffers in food is life threatening. The most poisonous parts are liver, skin, fish roe, but this does not mean that the meat does not contain poison.

There he is also present, but in smaller doses.

It is very important to cook the fugu correctly.

With the ingestion of fish inside begins the action of a strong nervously paralytic poison. First, the victim feels numbness of the extremities, then only his eyes remain mobile and respiration stops.

By sharp teeth and a formidable sight, it is not difficult to recognize it in a predator’s puffer. In order for other inhabitants of the aquarium not to suffer, it is better to put a partition wall or to settle the toby in another tank.

Pufferfish will feel comfortable in an aquarium of impressive size – about 200 liters. At the same time, it is necessary to take care of the heating, since the puffer-bast dabs in water at 23-30 ° C.

For puffer important water quality. Some species live in a lightly salted liquid.

The pH level should range from 7-8, and the hardness from 2.4 to 5 mEq / l. To reduce the hardness, you can boil water or stand for several days and drain only the upper layer.

To increase the hardness, add calcium or magnesium chloride, soda (1 tsp. To 50 l) to the water, or lay the bottom with corals, rapana shells.

Coarse sand is suitable for backfilling. Especially like to rummage in it fish called “architects” for their addiction to the construction of fancy circles on the seabed.

In this way, the white-spotted puffer arms settle the nest and attract the attention of females who are ready to continue the race with the courteous gentleman.

Corals are laid on the bottom of the aquarium

Decorate the fish habitat can be floating plants. If the algae roots are buried in the sand, the puffer will immediately uproot them.

The fish has frightening jaws. The teeth on them merge into 4 monolithic plates and can even have a bite to eat fishing gear. Iglobryukhov is called “chetyrekhzyubie” (lat.

Tetraodontidae). Individuals are voracious and require constant feeding.

The main ration includes live food, shellfish, shrimp, crabs, sea stars and hedgehogs, squid, fish pieces, mussels, minced meat. When using dry plankton it is necessary to soak it beforehand.

Sometimes you can use food for herbivores.

The puffer teeth are constantly growing, so solid food is a necessary component for grinding.

The real rarity is breeding in aquarium conditions

For breeding puffer fish in captivity, you must create the necessary conditions:

  • purchase a spawning tank with a capacity of at least 100 liters;
  • equip many secluded places – shelters;
  • plant plants with hard leaves;
  • wait for laying eggs.

If properly maintained, the puffer fish can breed in the aquarium.

At first, the individuals touchingly flirt with each other: walking in circles along the bottom, biting the partner on the cheek. Then the female lays up to 300 eggs on smooth stones, which the male fertilizes.

Then from the spawning one must pick up the female, and leave the offspring with the father. At first danger, he will protect the eggs, swelling in the form of a ball.

After 6-8 days, the larvae will appear, which the male will carefully transfer to the hole prepared in advance and will guard until the beginning of their independent feeding.

Despite the difficulties of rearing, fish of the puffer family remain to aquarists’ favorites due to non-standard behavior, exotic awesome maneuvers. However, you shouldn’t often bring the puffer-fish to the state of an inflated ball, as this will shorten the life of the pet.
