sand stirring

[fishtender]

Hi all,

I have read some controversy over samd bed movement.

Is it good to have things moving around in your DSB or not. I have a couple of nasarrius snails and was considering adding a bunch more. They really move around and do a good job cleaning. They tend to bury themselves in the sand though. Yeah....or....Nay?

Nassarius snails are fine for a DSB, they only go down into the very top layer of sand, and do not disturb the lower anoxic layers.
