When i checked on my tank this afternoon I found my nassarius snail eating one of my peppermint shrimps. Is it normal for these snails to go after live prey, when i researched it i only read that it eats leftover foods, and were great for cleaning the sand. I know that the shrimp wasnt dead before the snail started eating it because when i pulled the snail off the shrimp sortve feebily swam away before settling on the sand. Im kind of worried about my other peppermint now. Also i think the shrimp might have molted recently because i also pulled out a shell.
