Aquarium or aquatic shrimp is a common term for many types of shrimp. With a size slightly larger than the tip of a toothpick, the shrimp have many different names such as red cherry, bee, tiger, Kinh kong, red nose, white dot, green, yellow pumpkin … depending on the type.

This ornamental creature has a colorful appearance, eats vegetables in a glass tank, cleans the environment, so it easily “attracts” many players. Most of the common types of shrimp in Vietnam are originated from Japan, Taiwan, Indonesia …

More expensive, there are types of yellow shrimp, black shrimp, Kingkong, Panda, Red Ruby … from 100,000 VND to several million / animal.
