It's been five days since i last saw my little guy and im getting worried. I know nerites like to hide but he's just been gone. No ammonia spike in the tank and no smell in or around the tank to indicate he's dead. I've checked a bit of my substrate but stratum reallllly doesn't like to be disturbed. I put a nano banquet block in there, but I've never used them before so I can't tell if he ate some or if in 12 hours it's starting to dissolve.
