Upside down nerites

[KTpoopenstein]

I have 5 (I think, my little horned guy likes to hide) nerites in my 15gal tank. Both of my zebras and one of my tigers have been flipping themselves over onto their shells the last couple of days. They're definitely still alive as you can see them wiggling around, and if I turn them back over they'll crawl around a bit, but then flip over again a little while later. Anyone know what's going on, or are they just being weird? I just did a ~30% water change earlier this week, but more to top off the water level than because anything was out of whack. Ammonia and NO2 are both 0ppm and NO3 ~5ppm pH has been stable for months at ~7.4-7.6. No new additives to the water beyond what I've been using for months (prime, API leaf zone & CO2 booster, Flourish Excel). Thoughts?

My nerites do the same, usually when they fall off my plants or when climbing on the filter housing. Mine can usually turn themselves over but my baby nerites get stuck needing a little help from me!

I've been flipping them back over but they keep turning themselves back over. Weirdos.

That's a new one for me. I've seen them on their backs but they usually turn over, though not as fast as other snails do. Hope they are ok.

They're still doing it. One of them stays right side up longer than the other two, but they all still manage to flip themselves back upside done after a while. I'm at a loss.
