Shrimp are
extremely sensitive to rapid fluctuations. Unfortunately if you move one from one tank to another without a slow acclimation, it knocks them right out. Once there is cell damage the scavengers know it's time to move in.
Never, never, never skip the slow drip acclimation for shrimps even to move across the room (unless the tanks are on the same sump system maybe). I had to learn this the hard way too.
