How long is the life span of tiger fish?

Tiger fish, which is a kind of high-value fishing fish in freshwater rivers in Africa, has become more and more popular and loved by people in recent years. Now it is not only an alternative fish for arowana mixed culture, but also a darling in the tank. Common tiger species are Indonesian tiger, Thai tiger, Thai tiger and so on. Let's take a look at how long the life span of tiger fish is!

How long is the life span of tiger fish?

Theoretically speaking, the lifespan of Thai goby and Indonesian goby is about 16 years, but they can't live so long because of various problems. Wild tiger fish, for example, may lose their lives because they have to face attacks from natural predators or fish that are stronger or bigger than them in the environment, while tiger fish raised in fish tanks at home may be killed because of poor water quality, temperature discomfort and other bad breeding methods. In short, life is not easy, and raise and cherish.

What kind of food does tiger fish eat?

Tiger fish have strong vitality and are not easy to die from water. They mainly feed on crustaceans such as shrimp and crabs, small fish and clam larvae, some feed on benthic diatoms, and species living in fresh water also eat aquatic insects and worms. After bait, the tiger fish can adapt to some artificial feed, such as beef, bread worms, insects, fish nuggets, hamburgers and so on.

What's the best way to raise tiger fish?

1, breeding environment: the optimum water temperature of goby is 22 ~ 26 ℃, pH value is 6.5 ~ 7.5 (weak acid to neutral soft water, neutral alkali is better), it is very sensitive to water quality, if your goby body color is often unstable (too dark or discoloration), it is likely to be caused by water quality problems, please test whether ammonia nitrogen, nitrite and nitrate, PH value is in the normal range, and dissolved oxygen is sufficient. In addition, it may also be caused by space restrictions or attacks by other fish. If none of the above, you can consider adjusting the salt in the water, because some tiger fish like brackish and fresh water. We should try our best to imitate the natural environment, plant some aquatic plants, put some rocks and make some caves, or use some pottery flowerpots to simulate the caves, which can make the tiger fish happier. Sufficient dissolved oxygen and a certain amount of water are indispensable to the tiger fish.

2. Feeding management: when raising and feeding live food, it is recommended to wash and check in advance to see if the feed is contaminated. Crucian carp, carp, grass carp and so on should be scaled, visceral and Gill disinfected with salt water before they can be used, because river fish have a large number of parasitic bacteria and some parasites. Shrimp swords may stab fish in the stomach, leading to enteritis and digestive system diseases. Beef should remove the fat part to ensure that the digestion of fish is not slippery because of greasy. Other feeds also have to be processed, if lazy, these steps can be simplified, if you ignore this detail, it is likely to bring unnecessary losses, these are for the health of the fish.

3. Intestinal diseases: because the goby is a large predatory fish, it is hard to avoid being invaded by some external germs. generally speaking, the unified manifestation of intestinal diseases is that the excretory hole drags a white or yellow translucent object. it's already a little late when it can be seen by the naked eye. When the tiger fish gets this disease, the commonly used medicine is a mixture of gentamicin and furazolidone, and the dosage varies appropriately according to the size of the tank. Generally speaking, 800000 units of gentamicin per cubic meter is matched with 1.6g furazolidone. As for whether the disease can be cured, it depends on whether the fish is careful and the fish is born. Generally speaking, about 50% of the fish with gastrointestinal diseases can not escape this calamity.

4. Fungal infection: the most common disease of tiger fish is eye disease, that is, there is a layer of white cloud outside the eyes, and tiger fish seldom get parasitic eye disease. When the tiger fish shows such symptoms, it is likely to be a fungal infection after scratching. If it is not treated in time, it can lead to complete blindness of the whole eye in about 2 weeks. When you encounter such a problem, what you need to do is to eliminate the fungus. The method is to add furacilin (often called yellow powder) to the water to buy a large medical bag (with high purity). The dosage is 0.4 grams per 100 kg of water (200 jin). Furacilin is strong and not easy to dissolve, so you can stir in a small container before putting it, and pour the medicine into the jar together.

5. Erythema: it is dramatically called green beans. As the name implies, there are small red spots on the body of fish. The markings are of different shapes, including long, flat, round, or extracorporeal extension, mostly round. In severe cases, it can lead to perforation and shedding of the skin. When you encounter this disease, increase the amount of salt, with the use of potassium permanganate depends on the disease, generally speaking, the water in the tank is slightly purple, the effect is very good, malachite green can also be used with salt. I would like to emphasize here that salt refers to sea salt, that is, untreated after drying, household salt contains a lot of iodine, and high iodine content can directly make fish gills lose their respiratory function, which is one of the reasons why freshwater fish can not live in sea water.
