What to eat?

Piranha live in the mainstream and large tributaries, with wide rivers and fast currents. Adult fish mainly look for food at dawn and dusk, mainly insects, worms and fish, but some similar species only eat fruits and seeds, and their activities are mainly in the daytime. I will rest in a sheltered place at noon. Individuals hunt for fish of relatively small individuals, and in groups, they hunt anything that enters the water, including people, and they will actively attack anything that moves in the water, especially sensitive to the smell of blood. any smell of blood will provoke a frenzy of attacks by large groups of "piranha".

Piranha is a kind of freshwater carnivorous fish with different body length and sharp teeth, which is famous for its ferocity. And it generally has two categories, one is P genus, suitable for gregarious, and the other is S genus, which can only be raised alone. Their prices are also more diversified, some expensive and some cheap. For example, the price of gold Brandi is about 5000 yuan per piece; Allen piranha (seedling 2-4 cm 80-120 yuan / piece; 15 cm about 450,600 yuan / bar; Indian samurai (15-20 cm 1500-2200 yuan / bar; 22 cm + 2400-3000 yuan / bar); yellow diamond piranha (red-cheeked yellow diamond 10-15 cm 400-3000 yuan / bar). If the regional consumption difference is different, there will be some difference in price.

Introduction of natural enemies:

1. Electric eel: in order to deal with piranha, many fish have developed their own "cutting-edge weapons" in the competition for survival for thousands of years. For example, the high-voltage current emitted by an electric eel can send more than 30 piranha to the "electric chair" for death, and then slowly eat them.

2. Stinging catfish: the stinging catfish is good at using its sharp thorns. Once it is targeted by the piranha, it swims under the bottom piranha as fast as it can. No matter how the piranha swims, it moves synchronously. If the piranha wants to bite it, the thorn catfish immediately thorns angrily, making the piranha helpless, and the piranha ranks first in the Amazon killer list, while the piranha only ranks fourth.

Mixed fish:

1. Arowana: the arowana is domineering, spiritual and looks like a dragon. It is loved by more and more people. Coupled with the long-standing dragon culture of the Chinese nation, it is even more sought after by the Chinese. And because it has the meaning of dragon and tiger leap, it is the best choice for mixed culture, and mixed culture is very ornamental, Tianlong earth tiger, according to one side!

2. Tiger fish: Tiger fish are suitable for mixed culture of the same kind, such as Thai tiger and Indonesian tiger. Although there is a struggle between them, they can resolve themselves, and the whole tank looks domineering. Mixed cultivation of goby should try to imitate the natural environment, plant some aquatic plants, put some rocks, make some caves, or use some pottery flowerpots to simulate caves, which can make goby happier.

3. Rays: rays, also known as devil fish, are not active, with a depth of 5 to 100 meters. They often hide their bodies in the sand and mud. Some species are colorful and feed on small fish and crustaceans and benthos in the sand and mud. Although can be mixed with the tiger fish, but the size gap should not be too large, or the rays will chase the tiger fish.

4. Feifeng: Feifeng is a large ornamental fish of the genus Cyprinus Carpio of the family Cyprinidae, with a flattened body, red fins, horizontal stripes on the anal and caudal fins, and fat fins at the tail root. the characteristics of the mouth can help the owner clean the food residue of the fish tank, and Feifeng has a very auspicious meaning in the Chinese mind, so it is a suitable choice for mixed culture with tiger fish.

5. Silver version: silver plate fish is a kind of freshwater fish of the subfamily Cyprinidae of Cyprinidae, distributed in the streams of northern Guyana and Paraguay, and also distributed in Brazil. It is peculiar in shape, beautiful in color, active and gentle, gregarious swimming, easy to raise leather, like to hide in waters rich in fish and aquatic plants, and like eating aquatic plants, which can increase vitality to boring fish tanks.

Culture techniques:

1. Breeding preparation: friends who want to start raising water tigers must make the following preparations before raising water tigers. First, they must know their own characteristics and varieties, and then decide whether P belongs to water tiger or S to water tiger. Then decide whether or not to have bottom sand. Of course, p is suitable for group breeding, while S is suitable for monoculture. This has to be chosen according to personal preferences and market conditions. Group breeders need to prepare their minds for internal friction, in which the red ascitic water tiger is the least, while monoculture is not easy to get out of the state, which requires a lot of attention from fish friends.

2, purchase method: all fish friends should know that it is very important to choose a good fish to start with, and how to choose and buy piranha is also an issue of concern to many fish friends, which can be selected according to personal preferences, price, health status and other aspects.

Fish tank selection: if you choose a piranha tank, you have to see whether you are going to raise a piranha or a piranha to determine the size, and the most important thing to choose a tank is to test whether the filtration system is strong, whether there is water leakage, whether there are scratches, whether the equipment is complete, and so on.

4. Water quality management: I believe that those who have raised fish will pay great attention to the problem of water quality. Of course, the raising of piranha is no exception. Because many piranha grow in the turbid water of the Amazon, the piranha has strong adaptability and generally grows well in soft water from weak acid to neutral water. Then there is the temperature. It is recommended that it should not be lower than 20 degrees, and it is best to keep it above 24-26 degrees all the year round.

5, fish food choice: piranha's main food is some frozen blood worms, small mud carp, Loach or some edible fish offal, pork or some pellet feed. As far as eating is concerned, P is generally not picky about food, small fish, meat and so on, in addition, feeding diversity will be of great help to the health and body color of the piranha.

6. disease prevention and control: piranha is a good breed to raise, but it will still get sick. We must do a good job of prevention before finding piranha in these troubles. If prevention fails to achieve results, we should learn how to treat it.
