Hi - just got some blue cherry shrimp from LFS. Tested the water, the levels were very similar to mine (they're less than a mile away). I drip acclimated for an hour and a half, then put them in. They were swimming some upside down here and there, and now they're all piled on top of each other in the corner of the tank. I have the lights off but wanted to know if there's something I should be doing to keep them safe. I tried shrimp about 5 years ago, and it was a horrific Shrimpocalypse, and it's taken this long for me to get over it and try again. Want to do well by them this time.
