Amano Shrimp: Workers for your Aquarium

Caridina multidentata, sometimes caridinia japonica and otherwise known as Amano shrimp, are an extremely popular freshwater shrimp species to introduce to your aquarium. Takashi Amano, the famous hobbyist who discovered the species ability to eat large quantities of algae, introduced the Amano shrimp to aquarists. They are around one inch in length at the pet store and grow to be around 2 inches in length. They are the larger of the ornamental shrimp and are great at eating filamentous algae in aquariums.

The Right Community

Amano shrimp require little hands-on attention and like living in both large and small communities,and with other, non-predatory shrimp. Keeping at least a couple in your aquarium is plenty, but keep in mind that they rarely reproduce in a home aquarium. Amano shrimp only increase as you purchase them and put them in your tank, while other types of shrimp will happily colonize your aquarium.

An Environment to Thrive

Amano Shrimp love being in an environment with many aquatic plants where they can swim from plant to plant, jump, perch, and hide, so choosing the right plants for these shrimp is important. They like being in harder water with a current that moves at a moderate speed. As with other freshwater shrimp, be aware of ammonia and nitrite levels (ideally at 0 ppm for both), keep nitrates as close to 0ppm as possible, be careful with medications, and avoid copper by

making sure all products and medications for shrimp are shrimp-safe. AZOO Max Bio Balls are great for shrimp and nano aquariums, safely breaking down ammonia, nitrite, and nitrate to give shrimp a stable bio bacteria colony. Ideal water temperature is 72-85°F, increasing the metabolism of the shrimp and their activity levels! Water hardness of 8.0 dkh would be the most beneficial, along with a pH level between 6.5 and 7.5: Amano shrimp thrive in these ranges! Along with making sure all water chemical tests are at their recommended levels, make sure that water is changed at least twice a week for Amano shrimp.

While shrimp are pretty relaxed pets, they have a tendency to be aggravated by planaria, little flatworms that are pests to your aquarium animals. Getting rid of them can be difficult, but VIV hasmade a Glass Planaria Trap that is specially designed to remove planaria from your aquariumwithout chemicals or medication, keeping an organic environment for your plants and animals.

Feeding Time

Feeding Amano Shrimp is an easy feat. Known for being algae eaters, they enjoy feeding on various forms of soft algae in the aquarium. These shrimp can also eat naturally occurring food matter in a planted tank. Food accumulates on the bottom and shrimp enjoy scavenging as long as the tank is not kept too clean. If it is, there may not be enough natural food sources to support them. However, additional food can include:  raw green zucchini and AZOO Max Breed and AZOO Max Growth. Click on the images to learn more about these nutritious products.

             

There are also multiple useful feeding tools to keep food residue from invading your tank, as well. One product that would be very useful in shrimp feeding is the Glass Feeding Dish by VIV. It keeps excessive residue from floating around the tank and impurities from getting in the sand. Another VIV product is the Bottom Feeding Tube which is designed to easily fill the bottom feeding dish with food and easy to clean afterward. The duo would be great additions to use when feeding your new pets!

Full Lives

Amano Shrimp have a longer life span than the many popular shrimp species, living two to three years. They sometimes die right after being introduced to a new tank, likely from the stress of being transporting in the changes in water temperature. Making sure water conditions are right and food is plentiful (and keeping predators out of the tank) will ensure these shrimp should live full, healthy lives.
