Beijing Phu Quoc Underwater World is the first five-star marine aquarium in Beijing built by China and New Zealand, with Asia's longest acrylic underwater tunnel, and is one of the largest artificial "underwater world" in China. Here you can walk through the sea floor through a curved, transparent underwater moving tunnel, witnessing more than 20,000 different, near-constant marine life, ferocious sharks, beautiful salmon, colorful coral reef fish and so on. There are also more than 20 different theme display pools such as Amazon Freshwater Fish Show Tank, Seahorse Show Tank, Coral Reef Show Tank. Here you can not only learn a lot about marine life, but also appreciate the wonderful exotic style. The Russian mermaid and sea lion performances are wonderful and well worth a visit.
