Malaysian Trumpet Snails

so about 3 months or so ago i bought some MTS through here.
and since then i have not seen any of them grow to an inch. not even half an inch.
so i was just curious how long does it take for them to grow?

i even turned off my lights one night and waited for them to come out but all i saw was little ones.

Iv had some now for 3 years and some of them are now about 1.5 inches, i hardly see them, i normally see the smaller ones or furrows left in the substrate by the bigger ones

Oh. I see. Maybe the big ones barely come out?
