Ya, im pretty new to the game as well. Inverts such as shrimp and crabs are very sensative to salinity changes. I know alot of LFS
keep their water 1.021 give or take. Say the salinity in your aquarium is 1.024-1.025 thats a rather large leap for these animals. They could easily go into shock, or have severe stress only to die shortly after tank introduction. (my first shrimp was a CBS, I just floated him for 30 mins like the LFS
said then dumped him in. He did a few quick jerks, sank to the bottom and died about 5 hours later)
Alot of people use the drip acclimation method to acclimate their animals.
I personally find that letting my inverts float for 30 minutes, then adding a little bit of tank water to the bag every 10 minutes for 30 minutes works fine.
For fish, I generally float them for 30 mins, then add a large portion of tank water to the bag, and let them float another 10-20 mins.
The slower the acclimation the greater chance of your animals surviving. The drip method is by far the best possible way to give your animals the greatest change of survival. However for me, and alot of people in this hobby, we don't have hours to sit around and acclimate a single shrimp.
It's up to you how you want to do it. HTH
Good luck to you in your future purchases!
