    Hi Sammy - do you have an anemone in your tank?

    The shrimps might just be hiding aways after molting - they sometimes do this because their exoskeleton's are then very soft still, and they are scared of predation at this time.

    If you have a nemmie - then the shrimps might have gotten stuck on the anemone's tentacles, which could have possibly stung it to death - I have experienced this too many times before.....
    Therefor I do not keep cleaner shrimps in my reef tank anymore....

    No anemone, I'm not sure about hiding, I lost one over a month ago ??? He never appeared, that time I thought it could be his brother that ate him ???

    Now I've lost my last one ?

    When I feed my nennie some prawn, i've seen my shrimps jump right on top of it and pull the food out of its mouth... and its about 20cm in diameter, not small.....

    Just a thought, could you not possibly have a mantis shrimp or pistol shrimp hiding away in your LR?

    I have lost 4 cleaners and I have nothing that will eat them, their antenna get broken off and then they disappear. The first 2 I had for well over a year and then their antenna started getting shorter and then they are gone not at the same time weeks apart. What I have seen is I do have a very very big bristle worm. Wonder if he is the culprit.

    Interesting thought! I've seen some mean size bristle worms. I suppose after the cleaner's have moulted it's very opssible for a big bristle worm to take them on...

    Some bristle worms are known to eat their own.

    The next question is what salt mix is been used.

    maybe the shrimp are part of some huge conspiracy to separate the hard working aquarist from his cash? I have hermits in my tank and the go over absolutely everything, even sit on my starfish sometimes and he's fine with it, i've never seen them attack anything other that other hermits, so IMO they might not be to blame here. But what i have seen in some tanks is than when some stuff dies everythin comes along and takes a bit out of it and it dissapears eventually, could this be the story? where they have moulted, become defensless and picked off?
