The water quality testing expert, the young nerd Paul, only raised his head from the computer screen when he heard Carl's voice.
"Paul, come over and get to know each other. This is the colleague from China that my daughter Reina mentioned. His name is Jeff Zhang, and this is his dog, Famous. This is an amazing dog. The movie that it starred in is being screened at the Berlin Film Festival. Maybe it will even win some awards …" Karl introduced Zhang Zian.
"Uh, hello, I've heard of you!" Paul greeted Zhang Zian shyly, then waved at Famous. "Hello, Famous! I heard that the movie you acted in was great. If it wasn't for the fact that I can't leave here, I'd love to go to Berlin to watch a movie. "
Famous barked excitedly as a greeting.
"Hello! Nice to meet you! "Zhang Zian walked over and shook hands with Paul. From Carl's solemn introduction, he knew that the nerd-like expert played an important role in the aquarium.
When Paul shook hands, he realized that he was still wearing disposable rubber gloves, so he quickly took them off.
After some small talk, Paul learned the purpose of Zhang Zian's visit and enthusiastically explained the water quality testing platform that he was in charge of.
Water quality was the most basic of all for fish farming, especially for saltwater fish. It involved water temperature, salinity, specific gravity, PH value, nitrite, nitrate, silicate, phosphate, carbon dioxide, iron, calcium, and magnesium ions, and many other factors. The requirements were much higher than for freshwater fish. It was a complex system that often made novices flinch.
The surface of the water quality testing platform was very messy. There were test tubes, measuring cups, catheters, electronic testing pens, gravity gauges, test papers, reagents, and a large number of drugs and equipment that Zhang Zian couldn't name. They almost took up the entire platform. Many of the items were marked in German, and Zhang Zian didn't recognize a single word.
Paul's introduction was very enthusiastic, but Zhang Zian's English level was limited to daily conversation. When it came to these professional terms, he became timid and was confused after listening for a long time.
Carl saw his embarrassment and interrupted, "Paul, stop. Our guest just arrived. There's no need to rush. Let him look around first."
That was exactly what Zhang Zian was thinking. Although the content of the water quality test was complicated, there were actually rules to follow, or rather, routines, just like the if/else in computer language. Counter soldiers with arms, counter water with earth. He didn't need to study the principles. He just needed to learn how to operate the equipment, how to analyze the values, and how to adjust the water quality.
However, before he returned to Binhai City to take over the pet shop, he had visited some aquariums in other big cities. Those aquariums did not have a dedicated water quality testing station, nor were they equipped with a water quality testing expert. This was the difference in expertise.
The overall scale of the German pet market was not as large as that of China, but it was at least ten years ahead of China in terms of specialization and segmentation.
In addition, the German aquarium equipment was world-renowned, but equipment alone was not enough. The key was still the people who operated the equipment, just like how photography could not be done well with equipment alone.
Paul smiled embarrassedly and said to Zhang Zian, "Okay, when you need me, you can come and find me anytime."
"Thank you." Zhang Zian nodded at him gratefully. He was determined to learn as much as possible in the next few days. As long as he could learn thirty to forty percent of Paul's skills, it should be enough to take care of his own aquarium.
Carl took out two cans of cold beer from the fridge behind the water quality testing station and threw one of them to Zhang Zian. "Let's go. I'll show you around. If you have any questions, just ask."
As far as the eye could see, other than the entrance, the other three walls of the dark aquarium were filled with aquariums of various sizes. Some aquariums only had aquatic plants, some aquariums had corals, and even more aquariums had all kinds of fish. It was a bizarre and dazzling underwater world.
Compared to freshwater fish, saltwater fish were more colorful. Under the illumination of the halogen lamps, they swam in the water, shaking their heads and wagging their tails. Every one of them looked very healthy and full of energy.
Zhang Zian's eyes were dazzling, and his heart was full of envy. How much time, money, and energy had been spent to build such a huge aquarium?
Suddenly, out of the corner of his eye, he saw a medium-sized aquarium. In the corner of the aquarium were two or three round, white things. Inexplicably, he was shocked. He shuddered and had goosebumps all over his body!
In the dark aquarium, it was as if someone had suddenly squeezed his windpipe, making it difficult for him to breathe.
At first, he thought that he had seen wrongly, because that kind of thing should not be in an aquarium. This was Germany, not Los Angeles. It was not like he had traveled to some low-budget Hollywood horror film …
However, after taking a closer look, he knew that he had not seen wrongly.
There were a few white skulls, half buried in the sand and pebbles. Brown dead wood was twisted and tangled, slanted in the tank. A few emerald green aquatic plants came out of the eye sockets of the skulls, swaying gently with the weak water flow.
There were also a few spindle-shaped fish with grayish-green bodies and bright red bellies swimming in the water.
Why would there be skulls in an aquarium?
Could it be that this was a human meat bun shop or something that specialized in bringing customers over and killing them to feed the fish?
His weird imagination grew wildly in his mind like weeds. He looked down at Famous, seriously considering whether to turn around and run away … But Old Time Tea and the others were behind him. Even if there was danger, Old Time Tea would be there to take care of it.
"You don't look too good. You didn't get scared, did you?" Karl raised his head and took a big gulp of beer. He stared at Zhang Zian's face and said mischievously.
Zhang Zian pointed at the skulls in the aquarium tank, trembling with fear. "That's …"
"Of course it's fake. It's just my personal bad taste!" Karl laughed. "Everyone is shocked when they come here for the first time. Go closer and take a closer look."
Zhang Zian walked over to take a closer look. He had the tragic feeling that he couldn't catch a tiger cub without risking his wife.
When he got closer, he realized that the skulls were indeed fake. It was similar to the kind of prop used to scare people on Halloween. He was far away, and there was visual interference from the water. Coupled with the special lighting and atmosphere in the aquarium, he had mistakenly thought that it was real … It was really scary!
This place was the same as the pet shop in Berlin. Every display cabinet or aquarium tank had a label that stated what kind of animal was inside, as well as the habits and breeding methods of the animal.
After seeing that the skulls were fake, Zhang Zian relaxed and wiped away the cold sweat on his forehead. His gaze moved to the label, and he saw that it said Natteri. Origin: Peru.
In other words, this aquarium was raising the legendary piranha.
