I'll have to look into the conchs, but to be honest the golden headed
goby keeps my subtrate pretty well mashed around...if you've never seen
one, they fill their mouth with substrate and then sift it through their
gills, looking for little critters to eat...he keeps things stirred up
well enough that I have to go in every few days to re-level the sand bed
a bit (otherwise I get a tremendous mound in the middle, and am
practically bare on the sides).

I guess you have not read books about Deep Sand Bed setups...
This fish is actually work against you eating animals (sand dwellers)
you want to have in the sand. On opposite, snails he is recomending to
you are herbivourus so they are not danger to sand dwelling animals.
