At the beginning of 2003, many news media in China reported the problem of piranha destroying the environment continuously, and CCTV even made a special program for it. For a time, the most direct impact of these news is that the price of piranha in the fish market has doubled, and this "ancient species" that has appeared in the ornamental fish market in China for more than ten years has been "re-recognized".

In fact, "man-eating pomfret" appeared in the northern fish market as early as ten years ago. At that time, because of its so-called "cannibalism" selling point, it once set off a climax of breeding and buying. However, due to the high feeding cost (feeding meat and eating too much) and the monotonous color and rough appearance in adulthood, it has not entered the mainstream ornamental fish, and the price has quickly dropped to a low price of more than ten yuan or even several yuan. Even in many restaurants, there are "piranha" for sale. Most of them are raised by aquarium lovers. When I grow up, I have no place to raise, so I have to sell it to the hotel to "cross".

0no dgPxU2fj|b Recently, many domestic news media bombarded "cannibals" in turn. Although it is not "nonsense", it is also suspected of "worrying about the sky". Not to mention that "man-eating pomfret" attacks people or other large mammals in the Amazon basin of South America, where it originated (mostly in the case of floods and food shortages), even if it attacks people, it needs certain environmental preconditions -%Y5R2KOU * |) fr- `.
S 1Y'y/b-@ NL Aquarium lovers who have raised tropical fish know that tropical fish can only eat, breed and move normally at its proper water temperature, and "piranha" is also a "high-temperature fish" in tropical fish. The water temperature must be kept above 25 degrees to eat normally, and the breeding water temperature is higher. Look at the data quoted by domestic media-"Guangzhou and Nanning in China also belong to subtropical climate. 1 month minimum temperature Nanning 12.8℃, Guangzhou 13.4℃. The water temperature is basically suitable, so you can survive outdoors. " Isn't this a bit too dogmatic? Piranha can "survive" in the water temperature of more than ten degrees, but when the water temperature is lower than 20 degrees, it stops eating, and when it is lower than 15 degrees, it stops moving, and it is simply lying underwater "waiting for death"! It usually takes less than 24 hours to fly to its Amazon hometown! How can you have the ability to attack other animals? Probably only those low-temperature fish native to China will "attack" it, saying it's nice to attack, but actually it's "bullying", because piranhas can't resist in this low-temperature environment ... not to mention the north that has been frozen for four or five months.

"We saw in the aquarium that a piranha ate a fish ten times bigger than itself in the blink of an eye …" Which aquarium did you see? Cannibals only attack animals ten times (even dozens) bigger than themselves when they live in groups or are hungry, such as monkeys, otters or large birds. However, the harm of a single or several young piranhas raised by aquarium lovers is at best to bite the fingers of the breeder, just like scratching! Of course, it's better to be careful of adult piranhas. Their teeth are really fierce. It is against the laws of nature to say that piranhas eat fish ten times bigger than it. Where did it eat this "fish ten times bigger than it"? Does it have a stomach "ten times bigger than its body"? Or did it buy a refrigerator to keep it? How many weeks? This is not a joke told by reporters on purpose, is it? !

Of course, all the media that pay attention to "eating people's pomfret" have a good starting point (reporters can't "collude" with fishmongers to speculate on the price of mermaid pomfret, can they? Ha ha! ), which at least shows that people are more and more concerned about the environment around them, but a harmless fish species in China's natural environment is wronged in vain. I think it is unfair to be a "piranha"! In contrast, the "anglerfish" of Silurus requires less temperature and environment, has no economic value, and needs more social attention than piranhas. However, the so-called one side of the water and soil raises one side of the fish. Most fish from the tropics cannot survive for a long time in most water environments in China. After summer, they live through autumn, but in winter, they only "linger"!

Conclusion: As an early domesticated and artificially propagated wild fish, piranha is a common ornamental fish species. Please don't "turn pale at the mention of a tiger" and let them live freely in our aquarium! Aquarium merchants should not take the opportunity to raise prices and give them a better living space! j4H \ 0r & ampV hNu
D+e0j| X~:R Piranha feeding guide: It is best to choose 5 cm long young fish, and feed them with artificial feed or live bait such as earthworms at first, and then feed them with small fish or washed shredded pork when they grow up. Man-eating pomfret is lively and active, so it is not suitable to be kept in aquatic plants tanks. The feed water temperature should be controlled within the range of 25 -27 degrees, and the feed water should be kept weakly acidic and clean. Because piranha's teeth are sharp, we should pay more attention to feeding and feeding at ordinary times. It is not recommended to hold the meat by hand when feeding "map fish". This fish is a gregarious fish, and its ornamental value is not good when raised alone. It is recommended to raise at least one group, about 6 fish. However, if properly raised, it will grow rapidly, so it is necessary to prepare a large fish tank with the minimum recommended size of 100cm (length) X40cm (width) X60cm (height). As for reproduction, because it is more troublesome, it will not be introduced here.
