New pistol shrimp missing again

[Bmhowe]

I have had my tank going 1 year. Everything I have put in has done great. But I have put a candy cane pistol shrimp in twice. Once about 6 months ago, the other one week ago. Once they go in I never see or hear them again. The one last week went in where my yellow watchman is. Is this common?

Acclimation for shrimp is very important. Could be an issue with your method.
