One of the ten shrimp died during a one day transit (we are local) and the rest were not particularly active. I drip-acclimated the shrimp for 4 hours, dump them into a tank with a shriving colony of tens of red cherry shrimp. I saw only one shrimp exploring the tank the next day, and none whatsoever in the following week. I suspect that the shrimp were kept in acidic water and I should have drip-acclimated them longer. (My water parameter is ph 7.6, GH 8, and KH 9).
