When purchasing new shrimp there are a few important factors you need to be aware of. Shrimp are very sensitive to a change in water parameters. To ensure that your new shrimp have the best chance of survival follow the steps below.
1. Make sure that your tank is cycled. You can do this by testing the water using a test kit.
2. Make sure the water parameters are the same or close to the parameters listed in the description of the shrimp you purchased.
3. Acclimate your new shrimp to their new home before placing them in the tank. There are a few different methods you can use to acclimate your shrimp. In my experience the most effective and easiest method is drip acclimating. This is done by using an air line hose with an air stone on one end and an adjustable valve one the other end. Place the new shrimp in a container using only the water from the bag the shrimp arrived in. Place the end of the hose with air stone into the tank the shrimp will be going into. Position the end with the adjustable valve over the container with the shrimp. Adjust the valve so that the water is dripping from the valve 1 drop per second. Once the water in the container triples you should be ready to place the new shrimp in the tank but honestly the longer you let them drip acclimate the better especially if the shrimp are Taiwan Bees or expensive shrimp. Do not float a bag of shrimp like you would when buying fish from a pet store. This does not acclimate the shrimp to the ph, gh, and kh which shrimp are sensitive to. Plus you can't float breather bags which is what I use to ship them in.
If your tank is cycled, your water parameters are where they should be, and you acclimate the shrimp properly, you shouldn't have any problems. Don't be alarmed if the shrimp look as though they have lost their color or attempt to hide for a few days. This is something that happens when they are stressed. Give them some time to adjust and their color will come back and they will become more active.
