What fish are these?

[rdefino]

I looking for a a fish, and can't remember the name. I saw it at the LFS. It would scoop up a mouth full of sand and i guess clean it then spit it out it's gills. It was probably about 2 -3 inches long. Any idead?

Thanks

Sand Sifting Goby?

 

[Fluff]

I agree with Bearfan, sounds like a sand sifting goby. What color was it? My yellow watchman used to do that. There are several different types though. Here is a link to liveaquaria and some sand sifting gobies.
