I found this guy dead on the rock this afternoon. Since everyone else appears healthy, I'm assuming he was the victim of a shell-jacking, and not something more worrisome like water quality. Earlier I had also found a snail turned over on the back of its shell. Nerite snails are unable to right themselves when this occurs. I would have liked to put this guy under the microscope, but he was already starting to stink and I was on my way out the door when I noticed his corpse.



Marine tanks are certainly more violent than planted aquariums. I'm going to keep an eye out for any other activity, and fingers crossed that this isn't related to me screwing something up with the water change. I should probably get a bunch of empty shells to prevent any future outbreaks of violence, should that turn out to be what happened.
