Fish ball (with prickles and spikes): content, compatibility, reproduction, care, feeding, photo

The fish ball is a member of the free-fish or four-toothed family (Tetraodontidae). In nature, live in tropical and subtropical waters of Africa and Southeast Asia.

Together with fish-hedgehogs (Diodont. Ball fish and hedgehogs confused because of the ability to swell up in a spiny ball in danger. It is easy to distinguish.

  • The mouth of the fish ball is small, with full lips. The hedgehog – large, narrowed, resembles a beak.
  • On the jaws of a hedgehog, there is one dental plate each, and two in a ball fish.
  • Spines hedgehog pressed, when frightened up. The ball fish has short spikes on bare skin.
  • The body of the hedgehog in a longitudinal section is rectangular, narrowed to the tail. The ball has a drop shape.
  • Tetraodons or puffer (Tetraodon) are common as aquarium fish. Habitat: fresh and brackish flowing and standing bodies of water, coasts and estuaries of Oceania and the Indian Ocean.

    There are 23 species in nature.

    The body is elliptical, narrowed to the tail. The fins are transparent or with a flush of skin color, small. The eyes are large.

    In nature, there are specimens of 5.5–65 cm.

    Active when the backlight is on. At night and after feeding, they rest in a shelter.

    Swim in search of food in all areas of the aquarium. They love shelters.

    Predators, territorial, in general aquarium aggressive. Attack the fish larger.

    Violet fins are torn off.

    They gnaw and eat mollusks, snails – this is the main food. Eat prawns and crabs.

    Bullies, cut off plants, but rarely eat. Prone to jumping out of the jar.

    In aquariums, most species tolerate fresh water. Water salting is appropriate for certain species as an incentive for reproduction.

    With an individual character. The degree of aggression and hooliganism depends on the instance.

    Curious, watching activities outside the vessel, playful. They recognize the owner and actively require food.

    The feeling of satiety is absent, it is necessary to limit.

    The insides, caviar and milt are deadly poisonous. Skin excretions are less dangerous. Tetrodoxin contained in tissues causes paralysis, asphyxia.

    Without artificial life support systems, death is likely. And also the animal that ate the tetraodon will die.

    Another reason to keep in a specific aquarium.

    Lifestyles, conditions of tetraodon different types are similar.

    It lives in nature in the lower reaches of the Congo. The sides and back are yellow with black spots. Belly light.

    In the aquarium reaches a length of 10 cm. They live up to 10 years.

    The female is larger than the male. To spawn a couple deposited in a vessel of 150 liters with plants and shelters.

    The water temperature is raised to 26–28 ° C, and it is heavily fed. The female lays up to 250–300 eggs.

    Inhabits brackish standing and flowing waters of Southeast Asia. The color of the sides and back is bright yellow with a green tint, with black spots and patterns. The belly is white.

    They grow up to 10–12 cm in the aquarium. They live for 8–10 years.

    Gender differences are not identified. In captivity for an unknown reason do not breed.

    Dwarf tetraodon (Carinotetraodon travancoricus)

    Freshwater fish lives in standing and flowing waters of southern India. Color from green to yellow-brown. In length they grow up to 2.5–3.5 cm.

    They live 6–7 years.

    In the aquarium breeds. In mature males, a dark stripe appears on the abdomen.

    In females, the belly is rounded. To be divided into pairs in a species aquarium contain 6–8 individuals.

    To spawn a pair or a haremchik from the male and females are deposited. It requires an abundance of plants. The female willingly spawn on mosses.

    A male ready for spawning acquires a contrasting color.

    The female lays 8–15 eggs. Caviar is isolated from adult fish. Fry appear in 4–6 days.

    They are fed with “live dust”, a microworm. Top dressing – pounded boiled hard-boiled egg yolk.

    In 30–45 days – chopped live and frozen food, artemia.

    The degree of capriciousness depends on the type of tetraodone. Dwarf species are better adapted.

    • Vessel of any shape. Capacity for dwarf fish from 15 liters per individual. For one 10-15 cm – from 150 liters. For the flock – 70–80 liters per fish.
    • Soil and scenery without sharp fragments. Tetraodon scales are absent, skin is sensitive. Cleaning will help a dense substrate. Does not allow the penetration of organic matter in the lower layers of the soil.
    • Plants and snags serve as a refuge for fish. Can start to spoil the foliage, but not necessarily, and not all species.
    • Fish voracious, produce a lot of waste. External filtering is required. Productivity – 7–10 volumes of the aquarium per hour. Aeration if vessel is overcrowded.
    • Water temperature: 23–28 ° C.
    • Stiffness: 1.5–9 ° W.
    • Acidity: pH 6.5–8.
    • The lighting is standard, the light output is 40–60 lumens per liter of capacity. Fluorescent and LED lamps of cold light (from 6000 K) with high luminous efficiency are preferred. Light day – 10-12 hours.

    Replace 1/4 of the volume of water once a week. Clean the bottom of the aquarium from waste as needed.

    Accumulating excrement and food residue acidifies the water.

    The main food of tetraodons is snails. The teeth of the fish grow continuously.

    If you do not grind off the sink, you will have to manually. Given the spikes – an unpleasant procedure.

    Otherwise, the fish lose their appetite, get sick.

    Let’s bloodworm, coretru, tubemaker. Corer is preferred: not very high in calories and forcing fish to hunt.

    Live food produced in natural waters can be dangerous toxins, parasites and infection. Use proven suppliers.

    Frozen fodder, sea fish fillets, shrimp meat, boiled beef liver will do. If you eat plants, add to the diet plant food. Cucumber and cabbage, pumpkin and zucchini.

    Vitaminized food – crushed oatmeal, flakes.

    Dry food is not recommended. They reluctantly eat, sometimes refuse to eat at all.

    Feeding – 1-2 times a day. Do not seek to feed your fill, will not work. Enough food eaten in a couple of minutes.

    Required weekly fasting day. The plants will suffer – they will grow in a week.

    Tetraodon gets on badly with fish of other species. Small eats.

    Dwarf eat fins.

    Dwarf species with large predators are not compatible. Both may die. Tetraodones from 10 cm are able to protect themselves.

    The fish with spikes, swollen like a ball, will repel the appetite of the voracious catfish. Experienced aquarists recommend not to experiment, but to keep in a specific aquarium.

    Ichthyophthiriosis, odiniosis – diseases typical for smooth-skinned fish. Common parasitic diseases.

    Dangerous, in the form of neglected fish threaten death.

    • There is ichthyophthiriosis in the form of white plaques on the skin (“semolina”). It is treated with Sera Castopur according to the instructions. If the rash does not cover the entire body, start with half the recommended dose.
    • Oodiniosis is characterized by similar plaques with a golden sheen. Similarly apply JBL




    When properly handled, show signs of pets.

    Add charm to the aquarium. Combine the beauty of marine fish with freshwater content.

    Content and breeding is not standard. Little information about long-term maintenance, but aquarists respond positively.
