Little snails

[seriousdude5]

When I turn off the lights many a little snail come out of the rock work. They're quite small, smaller than a pea. And have a rounded shell Question is what are these guys they good or bad?

they're fine. I've nailed them down as baby nerite snails? I have quite the large amount of them

yes they come out to clean the glass at night . they do that just so you dont have to look at them during the day and can enjoy your tank. they are very considerate.
