So here's the story.
I got a large order of crs in on Wednesday . Drip acclimated for 9 hours and added them to my tank. Everybody was doing great until I came home from work today (Friday) to see 4 dead in the tank. Quickly removed the dead and fed the colony a little food.
I noticed 2 shrimp acting funny doing the jump in the water and floating down slowly landing on their side. I've seen this behavior before and I knew this is bad news. Took the shrimp out and put them in quarantine where they proceeded to lay on their backs twitching. Did a smallwater change added a bit of malafix aand an air stone.
Fast forward 4-5 hours. They are just chilling in quarantine looking much better. What do I do now? Add them back to the main tank?

Do you guys think I should be suspect of bacterial infection or just stressed from moving?
