How to Acclimate Freshwater Shrimp Safely

Published on 26 September 2025 at 13:40

Bringing home new shrimp is exciting, but they’re sensitive to sudden changes in water. Proper acclimation gives them the best chance of thriving in your aquarium. Follow this simple step-by-step guide to safely introduce your Neocaridina or Caridina shrimp.

 

Why Acclimation Matters


Shrimp are highly sensitive to changes in:

  • Temperature
  • pH
  • Hardness (GH/KH)
  • TDS (total dissolved solids)


Even small differences can shock them. Slow acclimation reduces stress and prevents losses.

 

Step-by-Step Acclimation

 

 

1. Float the Bag

 

  • Place the sealed shrimp bag in your tank for 20–30 minutes.
  • This equalises the temperature gradually.


 

2. Open and Secure the Bag


  • Open the bag and roll down the edges so it floats like a bowl.
  • Alternatively, empty the shrimp and bag water into a clean container.


 

3. Drip Acclimation (Best Method)


  • Use airline tubing and tie a loose knot.
  • Start a siphon from your aquarium into the shrimp container.
  • Aim for a slow drip — about 2–3 drops per second.
  • Allow at least 1–2 hours for the water volume to double or triple.

 

4. Transfer Shrimp (Not the Water)

 

  • Gently net the shrimp and place them into your tank.
  • Avoid adding bag water to your aquarium, as it may contain waste from transit.

 

5. Lights Off & Minimal Disturbance

 

  • Keep aquarium lights off for a few hours.
  • This reduces stress and helps them settle in.

 

Quick Tips for Success

 

✅ Always test your water first — stable, clean water is essential.

✅ Shrimp prefer tanks with plants, moss, and hiding places.

✅ Don’t feed them on the first day — let them graze naturally.

 

Final Thoughts

 

With the right acclimation process, your shrimp will settle quickly and start exploring their new home. Healthy acclimation = thriving colonies.
