Hey everyone, just had a quick question regarding nassarius snails. I have had my tank up for about a year now and all fish, hermits, turbo, and margarita snails are doing fine. Earlier in the year I added 10 nassarius snails to my tank, saw them for about 2 weeks and then they disappeared. I then bought several more a month or so later and it was the same thing. I am not thinking it had anything to do with water quality as everything else is thriving. I was thinking about buying some more soon but don't want to throw the money away on them. Does anyone have any ideas or had the same type of experience? Thanks!
