Did my nassatrius snail get eaten??

[AquariumDani]

I have 2 nasstrius snails (1 now), 5 astrea snails and a tiger conch.

I assume my tiger conch and astrea snails did not eat one of my nasstrius snails, but my nasstrius snail is not in its shell? Did my other nasstrius snail become a carnivore and EAT it's brother?!

Probably just died

My cleanup crew will eat a dead snail body within an hour. Voracious amphipods and bristle worms along with the 6 or so hermits usually eat the dead snail before I find out it died.
