I have about 10 marble-sized baby blue briggs. I noticed their shells looked thin, and you could see lines in them, and they were light brown. Not "blue" at all, nor creamy/rich-colored like when they were younger. I just did a water change two days ago (FYI I have soft acidic water), adding lots of calcium and baking soda. I do this usually, but I did extra during the water change. This morning I noticed some really strange growth. It looks like visor caps attached to their shells! However, this new shell growth is perfect-- just how the shell is supposed to be. It is very awkward-looking, jutting out directly from the bad parts of the shell, and makes the snails' shapes very strange. This is only happening to my babies, not the dad. Will it hurt them in the long run? What can I do?
