Should I leave dead snail shells in tank

[Dodgeylauren]

I have a lot of dead snails and I’m working on improving my set up. Is there any benefit to leaving the shells of the dead snails in my bowl?

The only benefit of leaving them in is that it's one less reason to mess with the bowl and potentially muck things up. Also, I suppose they provide a small amount of additional surface area for biofilm. If you're moving things around anyway and want to remove them, go for it.

I believe they provide calcium, which growing shrimp and snails both need.
