Amano Shrimp: Hardy Aquatic Companion

Amano Shrimp (Caridina multidentata) are a popular species of freshwater shrimp, known for their hardiness, versatility, and ability to control algae growth in the aquarium. These shrimp are not only beneficial for the aquarium, but they are also attractive to look at, making them a great addition to any freshwater setup. In this article, we’ll explore everything you need to know about keeping Amano Shrimp in your aquarium.

Natural Habitat

Amano Shrimp are native to the streams and rivers of Southeast Asia, where they are often found in heavily-vegetated areas. They prefer a slightly acidic to neutral pH, and a total hardness of 4-8 dGH. The water in their natural habitat is typically well-oxygenated, with plenty of hiding places, making it ideal for these shy and reclusive creatures.

Tank Requirements

Amano Shrimp are very adaptable, and can thrive in a wide range of water conditions. However, to keep them healthy and happy in your aquarium, it’s important to provide them with the right water parameters. They prefer a pH between 6.0 and 7.5, and a total hardness of 4-8 dGH. It’s also important to maintain stable water parameters and avoid sudden fluctuations.

When it comes to tank size, a 5-gallon tank (19liter) is suitable for a small colony of Amano Shrimp. However, if you’re planning on keeping a larger colony, you may need a bigger tank. As these shrimp are relatively active, they need plenty of swimming space, but they also appreciate plenty of hiding places, such as caves, plants, and other decorations.

Amano Shrimp are omnivores, which means that they will eat a variety of foods, including both plant and animal matter. A balanced diet for these shrimp should include a variety of foods, such as blanched vegetables, sinking pellets, and frozen or live foods. They are also known for their ability to control algae growth in the aquarium, making them an important part of any aquarium cleaning crew.


Amano Shrimp are relatively easy to breed in captivity, making them a great choice for those who want to start a breeding program. The breeding process begins with a mated pair of adult shrimp, which will lay eggs on the underside of leaves or other surfaces in the aquarium. The eggs hatch into larvae, which are carried by the female until they reach the juvenile stage.

To ensure successful breeding, it’s important to provide the right water conditions, as well as plenty of hiding places for the adult shrimp and their offspring. It’s also important to keep the water well-oxygenated, as this will help to prevent stress and promote healthy growth.


Amano Shrimp are a hardy, versatile, and beneficial species of freshwater shrimp that make a great addition to any aquarium. With the right water conditions, diet, and plenty of hiding places, you can keep these fascinating creatures healthy and happy for years to come.
