Hey Man... Are you the one that had a problem with the turbos eating enough in the first place, and moved them to the fuge not too long ago? Just trying to get my memories right...
My turbos to this allot too. Normally because they have fallen from a rock or the glass above. I always end up turning them right side up when I see them. If they don't move for a couple of days after I have righted them, I assume they have passed away, so I move them to a separate container, and if they start stinking or don't move for a week or so, off to the nearest ant pile they go.
The larger ones are known for starving in our tanks unless they are very dirty...
