What is this thing???

I ordered a cleaner crew from swf and they sent me something that was supposed to be a cucumber but I don't think that it was. I emailed them to find out what it was and never got a reply. It is about an inch thick and 4 1/2 inches long. It clings to my live rock and looks like its waste is my sand in a tube. I don't know what I should do with it, could it be harmful, should I keep it, is it beneficial because it sure isn't pretty!

well you didn't have to go as far as describing that way... Good luck with what ever the heck it is ? ? ? ?

I have a black cucumber that could be described in much the same way...
Although not very attractive, it does an excellent job cleaning the sand.
