Piranhas, known in China for their low-quality European and American horror films, are often known for their aggressive, swarms of dozens of species, and although not protected animals, they often have devastating effects on ecosystems when released by a silly fork and mixed into local waters.

However, the fish lives in the tropical rainforests of the Amazon basin, and the icy northern part of Germany does not meet their living conditions, and even if they accidentally escape from the hands of farmers, they will quickly freeze to death.

Piranhas are not aesthetically pleasing, and most people raise them out of curiosity, or a bad taste like Carl. The old man is retired, and he likes to play this kind of scaremongering prank, so it's no wonder that Reyna complains about his strange temper.

"The first time I came to the interview, I was so shocked that I almost called the police. Paul, a water testing expert, said.

"You called the police?" Carl scoffed, "You were screaming like a ten-year-old girl!"

"Absolutely not!" Paul hurriedly clarified.

While the two of them were talking to me, Zhang Zi'an carefully observed the aquarium where the piranhas were raised. Regardless of Carl's bad taste, the set of this aquarium is extremely successful, with aquatic plants, dead wood, skeletons, and a few green-backed and red-bellied swimming fish, combined with the surroundings, creating an eerie atmosphere that will surely be desired for those with a curious mind to have the same aquarium in their home.

Aquarium landscaping is a kind of entertainment that has emerged in recent years, and it is also an art, and even a landscaping artist specializing in aquarium landscaping was born.

The profits of opening an aquarium mainly come from two aspects, one is live sales, and the other is peripheral sales. Aquarium landscaping is one of the peripheral sales, the profit is very high, and it will not be affected by online shopping.

Zhang Zi'an considered making a similar landscape according to this aquarium and placing it in the store after returning to China, but he was afraid that he would frighten the children who entered the store, and if he was repeatedly labeled as "promoting violence and terrorism", it would be worth the loss.

Carl pulled out an aluminum bowl containing a dead fish with bulging eyes and slightly open lips.

"It's lunchtime, Jeff, would you like to feed those cute little fish?" he asked.

"No, I'll see you feed it. Zhang Zi'an was not interested, and he was even more afraid that his hand would be bitten off when feeding the fish - these piranhas in the aquarium are not small, basically ten centimeters long, and may suddenly jump out of the water.

Carl shrugged, opened the lid of the aquarium, picked up the tail of the dead fish, and submerged its upper body in the water.

As soon as the fish's head entered the water, the piranhas swam away as if frightened, hiding among the aquatic plants and behind dead wood branches. However, after a few moments, they realized that there was no danger, and immediately got out of their hiding place, rushed straight at the dead fish, opened their strong jaws, showed razor-sharp teeth, and bit down the fattest part near the chest and abdomen of the dead fish, tore off a piece of meat and swam away slightly, swallowed the meat, and then bit it again......

A few piranhas surrounded the dead fish, you bite me and I take a bite, and eat them separately, and within a few minutes, the upper body of the dead fish was gnawed into fish bones, and the water became slightly turbid.

"This is a wild piranha in Peru, if it is a second- or third-generation piranha farmed in captivity, they will not eat it if they throw a fish in it for half a day, and it will degenerate very much. Carl said, pulling the remaining half of the dead fish out of the water and throwing them into a garbage bag.

With the exception of these freshwater piranhas, most of the creatures here are marine creatures, some of which are rare or dangerous.

In a large aquarium, the white sea sand is lined with colorful corals, like beautiful sunflowers blooming on the seabed, the water is clear and transparent, the water surface is not alarmed, and a few tiny small fish swim around, which is a very common species. Zhang Zi'an thought it was a landscaping aquarium, but when he was about to pass by, he suddenly realized that something was wrong, and a certain place on the coral seemed to move.

When he looked closely, there seemed to be some kind of mollusk lurking in the area, which was very close in color to coral, and even formed a calcareous appearance like coral.

A small fish flicked its tail and gradually approached, unaware that it was about to die.

The coral-like mollusk suddenly moved, and several tentacles were like parachutes, enveloping the small fish at lightning speed.

The little fish struggled only briefly and then stopped moving, but there was no obvious bite on its body.

Zhang Zi'an gasped when he saw this, it was so toxic!

This is an extremely dangerous blue-ringed octopus, the kind of highly poisonous creature that is often warned by experts not to be kept by ordinary people without permission, and it is incurably poisonous, and may have stopped your breathing before the ambulance arrived.

It grabbed the small fish for lunch, and at the same time revealed its hiding place, knowing that there was no natural predator in the aquarium, but it was still as vigilant as in the wild, and its body flashed with faint blue streaks, quietly swam near another coral, filling its body into the gaps of the coral, and almost instantly changed the color and shape of its body, no different from the surrounding coral, waiting for the next prey to pass by.

"This animal is very dangerous, is there a lot of people who buy it?" Zhang Zi'an asked curiously.

Carl nodded, "It's okay." You know, the more niche pets are, the easier it is to form corresponding circles. There aren't many people who have marine pets, at least not as many as cats and dogs – although they are smaller, they are more willing to communicate with each other, because knowledge about marine pets is not as easy to find online as cat and dog breeding. In the circle of marine pets, the blue-ringed octopus is a very special one, and being able to raise a blue-ringed octopus often means that you are out of the entry-level rookie in the circle of marine pets, and you can be regarded as an advanced player. And, this little guy is beautiful, isn't it?"

"That's right. Zhang Zi'an admitted.

From the glimpse just now, I don't know if it's a psychological effect, he sensed that the soft golden body and bright blue stripes of the blue-ringed octopus have a certain fatal attraction, no wonder many marine pet players flock to it, not just out of curiosity like raising piranhas.

The blue-ringed octopus is not a protected animal, but he does not plan to introduce it to his pet store for sale, after all, it is too dangerous.

"Jeff, how many days are you going to stay here?" Karl asked.

Zhang Zi'an estimated, "Seven days at most." ”

"Then you still have a lot of time, how about settling down first?" Karl suggested to him.

That's exactly what I mean. Zhang Zi'an agreed.
