Is my vacuum broken?

Got two Trochus snails last week one of them is doing great and zooming around the tank and the other will move around for a few hours and then sit still for 18+ hours. I thought he was dead this morning until I picked him of the rock and he started swinging around in my hand. I put him in the sand and he’s moved maybe 3 inches since. He seems to be more active at night, sometimes he’s on the glass when I wake up, but other times he doesn’t move an inch. Is there anything that could be bothering him or is he lazy? He also has plenty to eat there is diatoms all over my sand and rock.

How's it doing? I haven't had the best luck with snails (yeah, snails of all things?), but mine will do that occasionally. He'll get back to work eventually.
