Green tetradone content in aquarium conditions

Aquarists often acquire exotic fish. The tetradon green was one of the popular varieties.

This fish has a special character. Tetradons are difficult to maintain in aquarium conditions, so experts do not recommend buying them to beginners, who cannot always follow all the rules for keeping and breeding aquatic pets.

Fish with an attractive and fascinating appearance require certain conditions.

Tetradons belong to the Iglobryuhi family. Fish of unusual appearance can be found in the regions of South and Southeast Asia: in Thailand, Malaysia, Myanmar, Cambodia, India, Vietnam, Sri Lanka, Indonesia and Singapore. Adult individuals inhabit freshwater bodies of water and rivers, which may have varying degrees of salinity.

Young tetradons can be found only in brackish waters off the coast.

In nature, there are about 100 species of these fish. The most popular ones are:

  1. African. The inhabitants of the African River Congo reach a length of 10 cm. The fishes are characterized by a light brown color, only the belly has a yellow tint. Dark spots are scattered around the body.
  2. Eight. This species is found in the waters of Thailand. It is distinguished by large eyes and a wide frontal part. The color of the eight tetradon resembles a tiger. The body is characterized by black or brown color. The whole body is covered with yellow spots and curving lines. Fish color may vary with age.
  3. Green, or spotted (Tetraodon nigroviridis). An interesting view can be found in the salty waters in Southeast Asia. The fish reaches a length of 17 cm. The Tetradon is characterized by a green color with black spots and a white belly.
  4. Dwarf, or yellow (Tetraodon lorteti Tirant). Bright fish can boast Indonesia, Malaysia and Indochina. Dwarf tetradons inhabit quiet rivers and reservoirs with stagnant water. The color of males and females is different: bright red belly and beautiful longitudinal stripes are characteristic of males, and light coloring and small stripes along the body are female. They grow no more than 6 cm in length.
  5. Kutkutya (Tetraodon cutcutia). In length, the fish reaches 10 cm, lives in salted water. Males are green, and females have a yellow color. The sides are decorated with mesh patterns. Fish prefer to spend a lot of time in the shade, so they need to make a lot of shelter for them.
  6. Figured (Tetraodon biocellatus). This species is common in Russia. Curly tetradons live in the fresh waters of small rivers and canals of Southeast Asia. Predators grow no more than 10 cm, characterized by a snow-white abdomen and elegant patterns of yellow and green shades on the upper part of the body. The back can be decorated with stains, stripes, circles and various lines.

All types of tetradons belong to the family of four-teeth predators. Since they release toxins, they should be handled with care: they should not be taken with bare hands, and the fish should be fed with tweezers.

The tetradon kutkutiya, in its normal state, is more like a rectangle of dark yellow color, with a lot of dark spots without a specific shape.

Each variety is distinguished not only by coloring, but also by the rules of content. Aquarists most often get green tetradons with which there are fewer problems in the care.

Green view was discovered in 1822. Habitats of predators – Africa and Asia.

The tetradon green is also known by such names as ball fish, bubble fish, nigroviridis, puffer fish and swollen fish. Spotted fish found in fresh and brackish waters. They can live both in groups and singly.

Their food is plants, snails, crustaceans and other invertebrates. Often these predators tear scales and fins from other underwater inhabitants.

Pufferfish is characterized by an oblong body and small fins. The back of the body seems to be compressed from the sides. The fish has a curved dorsal profile.

The highest point is in the middle of the back. Tetradon is known for its cute little mouth mouth.

Fish-ball has bulging eyes and a broad forehead. Because of this appearance it is difficult to believe that it is a predator. The jaws of the bubble fish are represented by cutting plates separated in the middle.

Jaw teeth serve as predator protection from enemies.

Species of ray-finned fishes of the igloo-bryus detachment family.

The color of individuals varies according to age. Adult fish have a green back with dark specks and a white belly. Young puffers less bright.

Spotted tetradons prefer a brackish aquatic environment. Juveniles can live in fresh water, because the fish are born in the rainy season.

Nigroviridisy live up to 10 years.

The tetradon is called a ball fish because it swells when it feels in danger. Noticing the enemy, he takes a spherical shape. It helps him in this unique valve in the mouth.

When a fish fills the mouth with water, it flexes the big muscle at its base, which stimulates the esophagus and stomach. Every sip leads to the fact that nigroviridis becomes larger.

When a fish swells, the protrusions on its abdomen and back of the body become noticeable, which cannot be seen in a calm state.

Thorns, giving the tetradon a formidable look, prevent the predator from attacking him. Puffers kill their opponents with poisonous mucus if they are eaten.

The content of green tetradon in an aquarium can cause difficulties even for an experienced aquarist. For one such fish, a tank of at least 100 l is needed. If you plan to contain a pair of puffers, then you will need a capacity of 200–300 liters.

It lives beautifully in a freshwater aquarium with rather large fish swimming in the water column .. Despite its small size, it is rather aggressive.

Under natural conditions, nigroviridis jump from puddle to puddle when it rains. Having found for themselves food, they return to the reservoirs.

So that the jumpers do not leave the tank, the container should be covered with a lid. In the aquarium should be placed plants and stones, which will serve as a shelter for the puffer, but they should not be too much, otherwise the tetradon will not be able to freely swim.

Since the spotted fish lack scales, they are very susceptible to disease and treatment. For adults, salt water should be picked up, since in fresh water they easily get sick and do not live long. Temperature conditions must be set within + 22 ° … + 27 ° C.

Water should be with an acidity of 8 pH and a hardness of 9-19 dGH. Tetradons are very sensitive to nitrates and ammonia.

In the aquarium should be a powerful filter, because the spotted predators leave a lot of waste. In addition, this device creates a current necessary for the inhabitants of river waters.

Every week you need to change about 30−40% of the volume of water.

Nigroviridis – territorial fish. If the artificial reservoir contains several tetradons, they will arrange fights because of the crowdedness.

With a large number of shelters puffer pieces will be less likely to come across each other’s eyes. In a large aquarium, each of them will have enough space to stay.

It inhabits water bodies with a temperature of + 23 … + 26 ° C, pH 7.0 and water hardness 10 ° dH.

The tetradon content in an aquarium is complicated by the fact that it quickly grows teeth, which it needs to be ground regularly, therefore mollusks with hard shells should be added to its daily diet.

Although green predators are omnivores, most often they choose protein foods. Under natural conditions, their diet consists of various invertebrates – shrimps, crabs – and plants. Aquarium nigroviridisov fed:

  • cereal
  • moth,
  • crab meat
  • fish fillets,
  • Artemia,
  • snails.

Tetradonov can be fed and dry feed. Experts recommend choosing products brand Tetra.

The company has developed specialized foods that help enhance the color of the fish. There are also options with lots of vitamins and mixes made specifically for fry.

Tetradonov can not overfeed. In nature, they constantly hunt to get food for themselves, and they do not need this in an artificial reservoir.

If you give an insatiable fish a lot of food, they will become very fat and will die at an early age.

Eats shrimp in shell, crayfish, crabs, occasionally live fish (not gold and live-bearer), snails, sometimes frozen food.

Tetradons are known for their aggressive nature. Usually they are kept separately, but some aquarists get along well with several individuals.

This suggests that each spotted predator is individual.

Young nigroviridisy slow and timid, but they soon begin to show their character. It is therefore not surprising that in the aquarium with several fish some species will begin to disappear.

Tetradons eat small fish, and in large species the fins are torn off. Sometimes puffers get along with the big inhabitants of the aquarium, but they should not be replaced with underwater pets with veil fins.

Spotted predators are usually kept separately, since other species of fish often require water with a composition that is not suitable for tetradons.

With insufficient feeding can bite bottom, even large fish.

Green aquarium tetradons are rarely bred. Usually fish are caught in their natural habitats and imported to different countries. So far, few aquarists have managed to breed nigroviridisov in artificial conditions.

Of the relatives of the spotted predator, only a dwarf tetradon is successfully bred.

Adult females puffer fish lay 200−300 eggs on a smooth surface. Usually the clutch is guarded by a male.

Fry hatch in 6−8 days. The first days of the tadpoles live at the bottom, but sometimes the male carries them into a pre-dug hole.

The diet of fry includes Nauplii Artemia and Microterms. As they grow, small tetradons are given small snails, cyclops, and dry specialized foods.
