I hardly ever see my turbos moving...I'll look at my tank later & their isomewhere different...lol...like Tim said...I have to add another dozen or so every 4-6 months cause either the hermits want their shells or I rhink I may have a pistol shrimp. I hear a couple of clicking sounds when lights out. Still haven't been able to see anything.

And those Nassaurius snails move big time. They are constantly working thru the sand & surfacing.
