I found my cleaner shrimp dead this morning just his outer body and a few internal parts. It just molted about 3 days ago. I have two small clownfish (1" or so), a bi-color blenny that rarely leaves his hole in his rock, a fire shrimp, and a few snails. Is it likely that one of these killed the cleaner shrimp? Or it just died and a snail ate it afterwards. Any have these fish kill their shrimp?
