Acclimate new freshwater shrimp, fish and snails by matching temperature first and then gradually mixing small amounts of aquarium water into the shipping water. The exact pace depends on livestock and the difference between waters, so keep the process calm, measured and species-aware.
At Razz Aquatics, we prioritize reducing abrupt changes—not rushing livestock straight from the bag into the aquarium.
Acclimation checklist
Prepare first Dim lights, test the aquarium and ensure it is fully cycled.
Match temperature Float the unopened bag where appropriate while monitoring conditions.
Mix gradually Add small amounts of tank water over time; avoid sudden chemistry change.
Transfer carefully Move livestock without adding shipping water to the aquarium when practical.
Simple acclimation process
Check the aquarium: ammonia and nitrite should be zero.
Dim lights and match temperature according to livestock and shipping method.
Move livestock to a clean container and add small amounts of aquarium water gradually.
Observe livestock; do not force a rigid timeline when conditions differ.
Transfer carefully, then keep lights low.
What not to do
Do not add shipping water to the aquarium just to speed up transfer.
Do not acclimate into an uncycled tank.
Do not make large chemistry corrections while livestock is acclimating.
