Does anyone have nerites in fresh water or brackish water that are breeding? I just got two for my brackish tank and they are laying eggs. I don't know if they will hatch. I've read online that they will breed in brackish water so I'm hoping they won't. Not sure how much salt they need to breed. My water is between 1.005 and 1.006 specific gravity. I am over-run with mts but I don't have to clean my sand! I just scoop out extra mts every couple of weeks. No problem. They do, however, get embedded in the filter media which is a pain. If I had to do it over again I would not get mts. There's no getting rid of them now.
