so, I was just setting up my new tank, suddenly I noticed my snails had weak shells, I just lightly touched and all of a sudden I heard a lil crack... HELP
Your experience will vary with the others. Cuttlefish bone is optional as there are other ways to build up the shell. It is often recommended just to ensure the shells do not erode further due to lack of calcium.Even i have to ask why do you use cuttlebone?i have never used it in my snail tank and they seem fine
