Golden Apple snail

[zoomo]

I have two Golden Apple snails in my tank and days go by and they dont seem to move or come out of their shell at all, i thought they were dead and picked one up but he started to move.
Whats the the deal with these? is there something wrong?

I had a similar problem a while back, he died soon after he started hiding out all the time.

Mine hide all day long and come out at night.
