No luck with shrimp

[Richer]

Whats the secret to keeping shrimp alive in a tank? The first time I bought a cleaner shrimp, it died less than a day after it was put into the tank. The shrimp was drip accimilated for 1.5 hours. This time, I decided to stick to a longer drip period of 3 hours. The shrimp was dead in the bucket before I even put it into the tank. The two peppermint shrimp seem to be ok, but time will tell. My drip consisted of two-three drips every second or so. FYI, the bucket is completely clean. Its used only for my salt tank, I've accimilated other things in this bucket before.. fish, snails, crabs, etc. All of which are still alive and doing quite well.
