What's up
grasshopper?
Have you thought about some small,
red-legged hermit crabs? The
red-legged, or
scarlet-legged variety are fairly peaceful little critters, and they do a pretty good job on your sand. I have a bunch of these guys in my tank as part of my "
clean-up crew" and they do a good job of cleaning things up.
Another thing you might consider is a few Nassarius snails. Now, I know that sounds ridiculous, SNAILS

Believe me, these little guys eat a ton of detritus from your sand. Most of the time they stay burrowed, underneath your sand. But, when it's feeding time, they come out and start eating, any left over food that the fish leave. Well, anything that the fish leave.[smiley=toilet.gif]
It's really cool to watch them come out of the sand too.
If no one in your area can get them, try JP at
