Never had snails before and this is my first saltwater tank I have 2 cerith and 4 nazirith and a red tipped hermit just shipped and came in today at first I could see both cerith and now ones gone but the other the shell looks empty I can't tell if it's inside it or what and none of the nazirith have moved from when I put them in the hermit crab looks like he's doing fine just exploring and eating there are no fish in the tank yet
