Other critters to stir sand

Those glass eels look awesome! Judging by size though I imagine shrimp and small fish wouldn't be safe with them.

I dig an under-sand tunnel system for my corys and bumblebee catfish, and they do work churning the sand. It's pvc tube sliced in half and laid around in a figure 8.

That tunnel system sounds absolutely fantastic.
