I acclimated my 2 shrimp by floating them to even out temperature.
Then added 3/4 cup of tank water to the bag. 20 minutes later I added another 3/4 cup of tank water. 20 minutes later I ploped them in the tank.
Both are vibrant and seem quite happy with the new surroundings. I even had both of them try to jump on my hand as I was moving frags around tonight.
Knock on wood...
