Zebra Nerite Snails Acclimation

[drfu]

Hi Fellow Reefers,
Newbie on saltwater here, have a few FW, and have a couple of questions about snails.

Question:
My LFS told me that Nerites are brackish snails even though they keep them in FW, how do I acclimate these? My plan is to keep two in my tank and one in the back water column of my AIO tank.

Thanks in advance!
