How To Acclimate Amano Shrimp?

How To Acclimate Amano Shrimp

Whether it’s a fish or snail, every aquatic life needs acclimation before transferring from certain water to another. You can never be too sure how they will react to the new environment. The most vulnerable aquatic life that needs this acclimation process is the shrimps. And today, we will talk about how to acclimate Amano shrimp to your tank.

To acclimate Amano shrimp, float the sealed bag containing the shrimp in the aquarium for 15-20 minutes to equalize the temperature. Then, set up a drip line using airline tubing, and control the drip rate to 1-2 drops per second. It’ll allow the aquarium water to mix with the bag water for 1-2 hours, or until the volume of water in the bag has doubled, before gently releasing the shrimp into the aquarium.

There is a lot to know before you start the procedure to acclimate Amano shrimp. Here you will get a detailed description of how you can buy Amano shrimp from the store and make them live in your fish tank.

Though Amano is a freshwater shrimp, it needs marine water to take its heir line further. But if you follow these steps closely, you can even acclimate the egg bearer Amano shrimp too.

How To Acclimate Amano Shrimps?

Even the tiniest change in water parameters can be a threat to Amano shrimp’s survival. But once they are acclimated to your fish tank, they will be there for a long time and will help you get a safe and clean water environment.

The first thing you need to understand is, no matter how much accurate you stay to this process, there will always be the chance of mortality. You can perform the procedure at its best, but a small percentage of mortality can still happen. And that is totally normal! No need to panic about that.

Before explaining the process, let me share with you that I have researched many ways, and trust me, this is the best way to perform the acclimation process, and it has the lowest mortality rate in shrimps. This process might be slightly different from the regular one, but I believe this is the better one! This method is both simple and effective. The Amano shrimps adjust to the new water perfectly in this way.

So, without any further ado, let’s jump straight to the process.

Things You Are Going To Need To Perform The Acclimation

  • An aquarium bucket which can hold four to five gallons of water
  • A lightweight (preferably plastic) spring clamp to hold the tube with the tank
  • Duct tape
  • An air regulator Valve
  • An extended air pump tube (long enough to reach the bucket to tank)

Step 1: Unpacking The Amano Shrimp Bag

After you get all the stuff mentioned earlier, it’s time to open the Amano shrimp container you might have ordered from any aquarium shop or online platform. One thing to keep in mind is that if you are making a spot purchase, always try to inspect the health and living condition of the shrimps you are buying.

If it’s an online purchase, try to mention you would like to buy young shrimps aged between six months to one year. The mortality rate will be dramatically high in the too young and too old shrimps.

After you get the shipping box or the packet you have brought from the store, don’t suddenly unwrap it in the bright light. If the shrimp has been in the shipping box for some time, it has adjusted with the dark atmosphere.

So firstly-

  1. Dim the light
  2. Can turn the light off it if you have a natural source of light
  3. The natural source of light shouldn’t be too bright.
  4. Dim the light placed in your Aquarium also.

The Amano shrimps can be severely susceptible if not handled correctly. And bright light can cause severe trauma and stress for them.  

Step 2: Inspecting The Amano Shrimps

After opening the bag, run a visual inspection on how the Amano shrimps are doing. At this stage, keep a close eye on things like-

  • Is there any dead shrimp yet?
  • Do all the Shrimp look active?
  • Are there any parasites in the package already?
  • Is the water dirtier than it should be?

If there is any dead shrimp and you have ordered the package online, you must take photos or make a short video of that dead shrimp before you open up the bag. In this way, you can let the seller know that there were already dead before you touched them.

Dead shrimp will raise the ammonia proportion in the water. After taking photos, take out the dead shrimp immediately and proceed to the next step carefully.

If there is any sign of existing parasites in the package, don’t pour the shrimps into your fish tank with your other fish immediately. Perform quarantine for them first. Take care of them and observe if they are healthy. After that, you may proceed with the other steps.

Step 3: Temperature testing

This is considered the most complicated and crucial part of Amano shrimp acclimation. There are different types of ways you can get this part done. People only talk about the water temperature when it comes to acclimating the shrimp, but you need to keep in mind the room temperature.

If your shrimp has come into a non-breathable plastic bag, then you can put it in your room temperature for a while, and then you can float it on your Aquarium. And after 20-25 minutes, when the water in the bag reaches the Aquarium’s water temperature level, you can open the bag and let the fish swim away by themselves.

It’s not the proper way to acclimate the fish as you don’t know what kind of parasites and polluted water that poly may carry! If you pour them directly, the other healthy fishes may suffer!

Amano shrimp are vulnerable to predation in aquariums with big, aggressive, or semi-aggressive fish, which will likely eat the shrimp given the chance.

Step 4: Start The Acclimation Process

  • At first, take a container and fill it with normal room temperature water.
  • Take the fish bag and check if the temperature closely matches the water temperature of the container.
  • Adjust the temperature by adding a little warm or cold water
  • Place the bag on the container
  • Leave it unopened for 20-25 minutes
  • After 25 minutes, open the fish bag and let the fish swim away by themselves.
  • Keep the moss in the container if it was in the fish bag previously.
  • Let them relax for a while
  • After 1-2 hour, start reducing the water from the container slowly
  • Do it slow and steady, don’t startle the fish
  • When most of the water is drained, start adding water from your fish tank to the container
  • After adding water from the fish tank for about an hour, you can pour the water back into the tank along with the Amano shrimps.

 If you follow these steps carefully, your Amano shrimp’s mortality rate will get minimal.

how long to acclimate amano shrimp?

The duration of acclimating Amano shrimps will depend on the type of acclimation. There are basically 2 types of acclimations for shrimps:

1. Drip Acclimation

This is a widely recommended method for acclimating Amano shrimp. It involves slowly dripping tank water into the container holding the shrimp, allowing them to gradually adjust to the new water parameters.

Here are the recommended durations for both of these methods:

Recommended duration for drip acclimation

This process should typically take 1-2 hours, depending on how different the water parameters are. Some sources suggest that it can be beneficial to extend this process up to 3 hours or more if the water parameters are drastically different.

2. Temperature Acclimation

This involves allowing the bag or container holding the shrimp to float in the aquarium water, enabling the water inside the bag to reach the same temperature as the aquarium water.

Recommended duration for temperature acclimation

This process typically takes around 20-25 minutes, allowing the water in the bag to reach the aquarium’s water temperature level.

how to acclimate shrimp without drip?

Acclimating shrimp without using the drip method can be done using the Floating Bag Method. This method is simpler but less precise than the drip method. Here’s how you can do it:

Floating Bag Method:

1. Float the Bag:

  • Once you receive your shrimp, do not open the bag immediately. Instead, float the sealed bag on the surface of your aquarium. This allows the water in the bag to slowly match the temperature of your aquarium water, reducing temperature shock.
  • This process usually takes about 15-30 minutes.

2. Open the Bag:

  • After the temperature has equalized, carefully open the bag.

3. Add Aquarium Water:

  • Gradually add small amounts of your aquarium water to the bag every 5-10 minutes. This will help the shrimp adjust to the water parameters of your aquarium slowly.
  • Continue this process for about 30-60 minutes, or longer if possible, to allow the shrimp to acclimate to the new water conditions.

4. Net and Transfer:

  • Once the shrimp have had time to acclimate, use a net to gently scoop them out of the bag and place them into the aquarium.
  • Avoid pouring the water from the bag into your aquarium to prevent introducing any contaminants or different water parameters.

5. Monitor the Shrimp:

  • Keep a close eye on the shrimp for the next few hours to days, watching for any signs of stress or discomfort.
  • Ensure that the aquarium conditions, including temperature, pH, and salinity, are within the appropriate range for the shrimp.


While the Floating Bag Method is less precise than the drip acclimation method, it is generally suitable for hardy species like Amano shrimp.

If the shrimp are being introduced to a tank with significantly different water parameters, a more gradual acclimation process, like drip acclimation, is recommended.

do snails need to be acclimated?

Yes, snails, like other aquatic creatures, should be acclimated before being introduced to a new aquarium environment. Acclimation is crucial to allow snails to adjust to the new water parameters, including temperature, pH, hardness, and salinity, and to reduce the risk of stress and shock, which can be harmful or even fatal.

Acclimation Process for Snails:

Floating Bag Method:

  • Float the sealed bag containing the snails on the surface of your aquarium to equalize the temperature, usually for about 15-30 minutes.
  • After the temperature has equalized, open the bag and gradually add small amounts of aquarium water to the bag every 5-10 minutes for about 30-60 minutes.
  • Use a net to transfer the snails to the aquarium, avoiding adding the bag water to the tank.

Drip Acclimation Method:

  • This method is more gradual and is especially recommended if the new environment has significantly different water parameters.
  • Use airline tubing to create a siphon and allow water to drip from the aquarium into the container holding the snails.
  • The dripping should be slow, and the process can take 1-2 hours or more, depending on the difference in water parameters.

Monitoring After Acclimation:

  • After acclimation, closely monitor the snails for any signs of stress or abnormal behavior.
  • Ensure that the aquarium conditions are suitable for the specific species of snail you have.


    While snails may seem hardy, sudden changes in water parameters can be detrimental to their health, so acclimation is an important step in ensuring their well-being in a new environment.

    Final Words

    Another thing to keep in mind while acclimating the Amano shrimps is, try to perform the procedure at night. Other than that, you are good to go! I hope you have the minimum mortality rate while acclimating your Amano shrimps!
