Snail Breeding

[SparKy697]

For snails that like to lay their eggs above the water line like mystery snails, How much room do they need above the water? Do they like to get their entire body above the water line before they lay? Or can I just leave a half inch or so of space above the water line?

i think it would be better to have 1.5-2" of space... they dont need to get their WHOLE body out, but they should have able to get most of it out.
