Aquariums: Snail ate my amano shrimp post context

This is after I initially caught the snail munching and I had knocked him off to try and save the shrimp but you can see his tail had already been eaten into. His mouth was still going tho so I thought he could make it but died shortly after. The other video is the golden snail coming back to finish him off. I suppose I could still be wrong and the shrimp was already dying even before all this? Idk but RIP little one
