Catfish are also eaten in the year when no one feeds them. Otherwise, the trace elements in the water in the tank alone are not enough to sustain life. Because catfish are omnivores, no matter what appears in the fish tank, as long as it can eat, it will choose to swallow it, even if it is the same kind of corpse.

First of all, catfish are tenacious and can survive in any situation, even if food is in short supply. Although the catfish is ugly, it is actually the most tenacious of all fish. According to the information on the internet, catfish should be regarded as omnivorous animals, which can eat floating objects on the water, small fish can also eat insects such as mice, flies and mosquitoes, and even choose to eat the same kind of corpses when food is scarce. Because of these characteristics, catfish generally don't die, and can survive strongly even in harsh environment.

Although Mr. Huang's family hasn't fed catfish for a year or so, the water in the catfish tank can attract some insects, such as mosquitoes and some insects that breed on the water surface, and can be used as food for catfish. Besides, the catfish in the fish tank must have died this year. At this time, other catfish will eat its body, so that these catfish can live for a year.

Second, what is catfish? Trash fish? It's too dirty to eat. Can catfish eat it? Netizen: Can eat! Previously, a video was circulated on the Internet. In the video, there were feces and dead mouse bodies in the sewage, which were eaten by catfish that swam over. Since then, catfish has become trash fish and polluted fish in human mouth, but this phenomenon can only show that catfish can survive in any environment, which does not mean that all catfish on the market come from this environment. Catfish on the market are basically cultured artificially, and the feeding environment is very clean and safe to eat.

Just because of these one-sided videos, it is really wrong to shut out delicious catfish, especially catfish, which is very delicious and nutritious, and is a very good nourishing food for some people with poor health. In other words, we should believe in the inspection process in our country. Unqualified food can't appear on the market, otherwise, when there are problems, many people will follow suit.

Finally: now my family wants to eat catfish, but we must stick to it, otherwise we can't make a dish with catfish the size of tadpoles.
