Hello, I have a golden mystery snail thats been having a lot of babies. This week I noticed that a bunch of them have some white fuzz looking stuff right on back spiral of their shells and I can’t find anything online that tells me what this is. I’ve read that mystery snails can delevop white fungus spots on their shells and some people have even seen floating fungus around their shells, but this seems to be different. Not all of them have it, and the ones that do don’t seem to be sick at all, they’re eating and moving around the tank. Any idea what the white fuzz is and what could be causing it?
