cleaner shrimp problem?

[mike31154]

I have two cleaners, added consecutively about a year apart. Both are fine and I acclimated each for about an hour, maybe hour and a half. Are you certain that the one you say died is actually dead? Don't know the size of tank but if it's a large system the other one may be hiding after moulting. They will often moult not long after being introduced and the moult will look very much like a complete, dead shrimp.
