Thanks to everyone who is reading this post
I'm worried about my ivory snail. It is usually a pretty active snail, moving around day and night eating algae and food that falls to the bottom. for the past two days, however, I've found it staying inside of its shell, and isn't even attached to anything - it just sort of floats/lays on the edge of its shell. If it wanted darkness, there's a hiding place where it usually hangs out, so it's not that. I can tell it's still alive, and I've now quarantined it in case it's sick.
Is this normal for a snail? What could be wrong? What should I do?
I have: 10 gallon tank
5 zebra danios
2 cory cats
1 ivory snail
