Yes, it was released artificially, because there is no such species in our country, and it belongs to an alien invasive species. Since there is no such thing in our country, how can there be such a thing in our community pond? If it weren't for artificial breeding and relaxation, there would be no such creatures in China's waters because they are very dangerous. It has no natural enemies in the water and can eat all fish, shrimp and so on. So it is particularly dangerous to put this kind of thing in water, so how can such a dangerous alien species be introduced?

Then some people may be curious. Since the introduction of this species is not allowed in our country, why are there so many in China? In fact, many people regard it as an ornamental fish and then sneak into China. At first, many people raised it as an ornamental fish. Later, when they raised it, they found that they couldn't afford it, or there were not enough fish tanks, so they released it into the pond. In fact, I don't quite understand this kind of person's mentality, because when we look at the pictures, we will find that such fish are particularly ugly and scary, and everyone is afraid to look at them, whether they are small or big.

Why are ornamental fish called ornamental fish? Because it is ornamental, at least it looks good, but such a fish is so scary, how can it look good? So I really don't know much about those people who can raise this kind of fish. Maybe it's because they followed the trend at first. When they saw someone around them, they followed. Crocodiles and eels eat all kinds of fish and are basically not picky eaters. If you keep this kind of fish, you need to spend a lot of money on feed every day. Some people can't afford it, so they just throw it away. This behavior is actually very irresponsible, because if you throw it into the water, it will cause great damage to the local waters.
