I got a racer nerite snail about a week ago and I was wondering if nerite snails are nocturnal. Mine barely moves during the day but at night, it seems to teleport. I don't know if this is usual nerite snail behavior because I've never kept one before and the ones I saw on a friend's tank were pretty active. One reason why I got them was mostly because of algae in my 10g. Can't really tell a difference after a week and there wasn't even a lot to begin with. There's usually a trail of teeth marks if a nerite is eating algae but I can't seem to find any. At first I thought it was because it was adjusting but after a week, I'm not so sure.
