Question 2: What kind of fish can I mix with pufferfish? River, commonly known as "puffer fish". Scleractinian family of fish collectively. River body is cylindrical, with the well-known round body, the general body length of 100 to 300mm or so, large up to 630mm or more. The upper and lower jaws are fused with teeth to form four large plates, and the body length can reach 1.1 M. There is one dorsal fin and no ventral fin. No scales or small spines. It has air sacs that can inhale and expand. There are many species, most of which live in the sea, but can also be found in fresh water and at the confluence of sea and fresh water. They blow water and air through the water, causing sediment to fly up and then prey on creatures hiding in the sand. Because the teeth and jaws are hard, they can bite even extremely hard shells. The whole is oval, bluntly rounded in front and tapering at the tail. The muzzle is short, rounded; the mouth is small, terminal, and transverse. Upper and lower jaws each with 2 plate-like incisors, with a distinct mesial suture. Lips well-developed, both ends of lower lip curved upward on outer side of upper lip. Eyes small, gill pores small, a curved slit, located in front of the pectoral fins, body surface densely covered with small spines. Dorsal fin very posterior to anal fin; no ventral fin; caudal fin flat-truncated at posterior end. The dorsum of the body is grayish brown, the sides of the body are slightly yellowish brown, and the ventral surface is white; the markings on the dorsum and sides of the body vary with species.
Every year in March from the outer sea swim to the mouth of the river in the fresh and salt water areas to spawn. Only the dark Oriental a group of anadromous into the freshwater, May to June in the river in the spawning; carrying the amount of eggs is generally between 4 to 50,000 grains. In the fall, the water temperature drops, the river begins to descend, and like other species swim to the deep sea area, returning to the deep sea area in early December to overwinter. The young fish born that year live in the rivers or lakes through the river, and return to the sea only in the spring of the following year, growing up to sexual maturity in the sea and then re-entering the rivers to spawn. They enter the Yangtze River in April to June, and spawn in the middle reaches of the river or in Dongting Lake and Poyang Lake.
Food
The river is omnivorous, feeding on fish, shrimp, crabs, shellfish, but also eating insect larvae, branches and horns, copepods, as well as leaves of higher plants and filamentous algae. In the reproductive migration period is generally rarely ingested.
Self-defense
The river has a body size of *** and relies primarily on its pectoral fins for propulsion. This size

Although it can rotate nimbly, it is not fast, making it an easy target to hunt. As a result, the river has evolved a self-defense mechanism that is quite different from that of normal fish. When threatened, the river is able to quickly draw water or air into its highly elastic stomach, expanding to several times its size in a short time to scare off predators. The spiny rivers of the Echinodermata family even have thorns on their bodies, and when they expand, the thorns rise up all over their bodies, making it difficult for predators to swallow them.
As the river's diet is omnivorous, it feeds on fish, shrimp, crabs, and shellfish, as well as insect larvae, branchiopods, copepods, and leaves of higher plants and filamentous algae. Generally, it rarely feeds during the reproductive migration period. So try not to mix with fish as appropriate.
Question 3: Puffer fish and what fish can be raised together Roughly speaking, only if it is not a meat-eating fish can be raised together with puffer fish. The details are too much (cell phone typing, bitter ah::>_ Question 4: puffer fish can be raised with goldfish No, I bought my green puffer fish, but also bought a lot of small fish to give them to eat, they are really good at eating ah, an average of 5 a day (two green puffer fish, a 8 word puffer fish), super appetite. Sometimes they eat so much that their tummies are bulging, like big bellies.
As for the goldfish, usually as a pufferfish snack, swim slowly and a lot of fins, quite suitable for pufferfish appetite, keep pufferfish people will feed every once in a while (I have not tried, too cruel, I am feeding shrimp).
Wild pufferfish eat snails, clams, shrimp and small fish, in short, they eat meat.
Don't think it's so kind just because it's so cute.
Anyway, don't mix it with your goldfish, or the goldfish will suffer.
Question 5: Beginners seek advice: puffer fish and what fish can be mixed puffer fish can be kept alone, try not to and other fish together, because the puffer fish this will be up, you can go to the fish shoot network to see, there are a lot of expert experience
Question 6: What is suitable for raising with the puffer fish? (a) Mainly raising puffer fish mixed with bighead carp When the puffer fish fry grows to 5-6 cm, its weight can reach about 2 grams, and the stocking density per 667 square meters is 4,000-5,000 tails, with the eel with the specification of about 50 grams of 70-100 tails or 50 tails of bighead carp and silver carp each. When breeding commercial puffer fish, you can put 800 to 1,200 puffer fish species of about 100 grams per 667 square meters, and mix 50 silver carp of about 500 grams or 20 to 30 silver carp and bighead carp of about 500 grams each. In this way, the leftover bait and feces of puffer fish can promote the growth of plankton, and bighead carp and silver carp can make use of the plankton in the pond, which can not only improve the aquatic environment of pond culture, but also improve the loading capacity of the water body and the breeding efficiency. As long as attention is paid to water quality control, feeding techniques are mastered, and fish disease prevention and control are strengthened, the survival rate of puffer fish breeding can reach about 90%. The weight of puffer fish species at the end of the year can reach 100-150 grams l tail, and the specification of commercial puffer fish at the end of the year can reach 350-400 grams / tail.
(B) Blowfish and car shrimp mixed culture It is reported that in 1996, Dalian Yongan Food Co., Ltd. in Zhuanghe City, Liaoning Province, Guanjiaoshan Township, after repeated research on the habits of red finned oriental, car shrimp, decided to blowfish and car shrimp mixed culture. They introduced 10,000 puffer fish fry through scientific research institutions and planted them in 8 hectares of shrimp ponds (5.3 hectares and 2.5 hectares). 3 hectares and 2.7 hectares of two shrimp ponds). They introduced 10,000 puffer fish fry through scientific research organizations and mixed them with car shrimp in 8 hectares of shrimp ponds (5.3 hectares and 2.7 hectares). Proven by experiments: car shrimp lurking underwater during the day, the night out to feed, while the puffer fish during the day to feed, lurking underwater at night, car shrimp leftover residual bait, puffer fish continue to eat without additional bait, and some of the sick and injured car shrimp were also eaten by the puffer fish, the two have a great complementarity, not only the car shrimp survival rate is high, and puffer fish growth, harvested that year, 3,000 kg of shrimp car shrimp, puffer fish about 7,000 kg, and achieved a very Considerable economic benefits. Car shrimp, pufferfish mixed success for the entire Yellow Sea, Bohai Sea coast shrimp industry out of the doldrums brought hope.
(C) puffer fish and Chinese shrimp mix-farming April 1996 to November 1997, Tanghai County, Hebei Province, successfully carried out the red fins of the Oriental and Chinese shrimp mix-farming practice to explore. Jiangsu Ganyu County, East Township, under the mouth of the village in 1997 to carry out the redfin Oriental and Chinese shrimp mixed culture test, now will be mixed with the technical points are described below.
First, the pond area is generally 2.7 to 3.5 meters. 7 ~ 3.3 hectares, the average water depth of 2.5 meters. 3 hectares, an average depth of 2 meters, sufficient water without pollution, PH value of 5.9 to 9.5 meters. 9 ~ 9 . 8, high transparency, breeding ponds have a perfect drainage and irrigation system, the water intake gate should be installed 60 mesh water intake net, drainage gate installed 7 mesh wire mesh and 8 mesh safety net.
Secondly, before releasing the fish, first dry pond sunshine, disinfection, pond leveling. Every 667 square meters of water surface, water depth of 1 meter, the use of quicklime 70 kg and bleaching powder 6 kg, or the use of tea bran 5 kg and bleaching powder 3 kg, or tea bran 35 kg and quicklime 45 kg sprinkled, clear the pond 2 days after the appropriate time into the water.
Third, the fish species for the greenhouse overwintering species, the average size of about 150 grams / tail. When entering the pond, the water temperature is stable at more than 15 ℃, the salinity of the pond is slightly lower than that of the overwintering pond, and the short-distance transportation can be done by packing 600-800 fish seeds (specification of 100-150 grams/tail) into a 25-cubic-meter canvas basket. Before entering the pool with a concentration of 10-15 mg / liter furacilin bath for 20-30 minutes, or 50 mg / liter formalin bath for a few minutes.
Fourth, the stocking density depends on the pond conditions, water exchange, bait supply, breeding techniques, listing specifications and planned production. Each 667 square meters of pond put the puffer fish 80 ~ 100 tail, China shrimp 6000 ~ 8000 tail, the fish species should be a full release.
Fifth, the feed is often frozen mackerel, sardines, spiny fish and shrimp, brine shrimp, etc., the bait should be fresh. Low water temperature, the daily bait for fish weight 1 . 5% to 5%, the daily bait in the fall fattening period of 6% to 10%, bait coefficient of 7 or so, after the autumnal equinox should be appropriate to reduce the amount of daily bait 2 times in a certain range of the water surface in turn, the morning cast the daily bait 55%, the rest of the afternoon feeding, to do not throw spoiled bait, fish do not throw oxygen, water temperature higher than 30 ℃, less cast, fish grow fast more casting until the fish listed on the market, can not be interrupted to cast the bait.
Sixth, aquaculture management: A ． Water level control at 1.2 to 2 meters. 2 ~ 2 meters, low water level in the early stage, high water level in the middle and late stage, in order to facilitate the fresh water quality and water temperature constancy. The first 7 days of water change 1 time, each ...... >>
Question 7: Puffer fish and other fish are kept together, other fish will be toxic? No, puffer fish is visceral toxic
Question 8: Puffer fish and tropical fish mixed together, to be tight?! No, puffer fish can release toxins that can kill other fish, and don't touch them when your hands are injured
Question 9: Can I mix goldfish with puffer fish? Although they are freshwater fish, but still do not mix: 1 watch palm puffer fish require high water temperatures, the winter water to be warmed, the goldfish do not need to be warmed over the winter. 2 Puffer fish seem to be loyal, but in fact, do not touch them when your hands are hurt. 2 The pufferfish seems to be loyal, but in fact, it is quite ferocious, and the goldfish will be attacked by it. 3 The puffer fish is very strong in foraging; the goldfish is poor in foraging and has a large amount of food, which makes it impossible for it to compete for enough food. 4 The fins of the puffer fish are poisonous and may sting the goldfish, causing injury or even death to the goldfish.
