I just bought 4 hermit crabs and they are doing a pretty good job at cleaning my sand but they have since moved on to my live rock. I was thinking about buying a sand sifter cucumber but the black species are kind of ugly. Do the yellows sift sand? I have a mandarin goby and a lawnmower blenny, could I add a sand cleaning goby or blenny? I am not sure wich species is the one that cleans sand???
