Fish that shoots gravel out of its gills?

[Kadina]

My daughter and I spent some time admiring the 700 gallon reef tank at my lfs tonight ("See Nemo Mommy? See! See!"). We saw a long cylindrical shaped white fish with pale pinkish stripes that would take a huge mouth full of the gravel/sand in the tank and the spit it out on either side from what looked like his gills. It was a spectacular site to see and elicited alot of questions from my 2 year old about the fish eating "dirt". Unfortunately I couldn't answer her because I had never seen anything like it. I googled a bit but can't seem to ID the fish and I did not have my camera with me at the store. Any ideas?

could it be a sandsifting goby? i had one, he spent every single second he would grab sand, shoot it out, repeat

Sounds like a goby to me... try a google search for these and see if it looks like your fish!

Pink Spotted Watchman Goby --> Cryptocentrus Leptocephals
Pinkbar Goby --> Cryptocentrus Aurora
