I woke up this morning to find 6 fatalities in my tank. Thankfully they were only snails ;D but it seems odd to me that all of them would die overnight. My cerith population appear unaffected and all other livestock open fully or acting normally. My current suspect are the hermits (5), but they are tiny and that would have been some killing spree! I tested tank parameters, but they all came up clean. Do I have the beginnings of a problem? Thanks in advance - John
