Who's your favourite (or not) sand sifter ?

I love my diamond watchman goby. She keeps the sand super clean and is quite a personable fish.

That being said I wouldn't mind if he did stop moving all the sand into the middle of the tank...

My arm, hand & a siphon tube are my favourite sand sifting critters. I stir things up a bit when I do water changes. Since I don't have a sump, that's a regular routine in the display every 20 days or so.
