Sand sifter's?
 

What creature would be best to mix up or stir the sand in my tank that is reef safe??

I have a 6 spot sleeper goby that does an awesome job.

conch :biggrin:

Was wondering the same thing. What would be good in a 10G?

A strawberry conch would fit well in a 10g. Mine is only about an inch and a half long, so as long as it's not all sand in there, he should be fine.

My yellow watchman goby sifts my sand, but also I have a few nassarius snails that do a really good job of keeping the sand clean. I recommend the nassarius snails for nanos... they get the job done !
