Just to throw in my 2 cents worth here. It's due to acclimation. I killed my first 2 peppermint shrimps by only acclimating for just over an hour. After , what I thought was a good enough time for acclimation, my shrimps died in 2 hours. All water params were perfect. I went back to the LFS
and purchased 2 more shrimp.
But, this time I acclimated them with a slow drip for 4 hours. This was 2 months ago and my shrimp are still fine to this day!
Inverts are very sensitive to salinity changes, especially rapid ones in my case. I tested the LFS
water with the shrimps in it, the SG
was 1.020. My tank is at 1.025. The slow drip and acclimation took four hours cause I wanted the water the shrimp were in to match the exact temperature and SG
of my tank.
4 hours may seem a bit excessive, but I didn't want to do another 3 hour round trip to my closest not so Local Fish Store!
