What do nerite snail hatchlings look like?
For months my white cloud minnow tank had just one zebra nerite snail to keep down the algae but it soon became clear that I was going to need another. So, then there were two. One was very big and one about half as large and I assumed I had a male and a female. My original (female) snail had always layed eggs but of course they never hatched because even with only one snail, my tank was freshwater. But now, I have about a dozen very small little snails in my tank that are not pond snails (These breed in this tank too and do not look like these guys). They are about as large as the nerite's eggs, almost flat and their shell almost clear. On the glass I see them scraping their tongues on the algae like the nerites but here's the thing - I've never seen them move. I leave the room and they've gone an inch further along but I can look at them and not see them move a muscle. Pond snails move quickly enough to see. Not these. They first showed up about 2 weeks ago, long enough to think that if they were nerites they should have died right away from the lack of brackish water. But they're still around. Has anybody had nerites breed in freshwater, or else what kind of snails could they be? I haven't added any new plants that could have held eggs in months.
