sand and bacteria

there was an article in today's newspaper (can't recall if it was the Toronto Star or the Globe and Mail) reporting on a study showing that sand contains far more bacteria than there is present in the water column. this was in reference to how bathing conditions at beaches are considered. (e. coli levels for example.) bacteria live longer in the sand than they do in the water column as well. i wonder.... perhaps in an aquarium the bacterial count in a sand substrate is even higher than it would be on a beach because there are no waves washing through it. i'm thinking now of the survival problems related to mooseface and horseface loaches. perhaps it's a factor and a consideration in the degree of difficulty in keeping these fish alive in captivity.

just a thought.
