Shell-0’s are a fantastic supplement! Our goal is provide a suppliement to ensure growth of a strong shell and provides essential calcium stores for Mama’s who are laying eggs. Shell-O’s consist of pure calcium carbonate and a little Spirulina for a yummy flavor!


Shell-O’s can be offered 2-3 times a week and can remain in tank until they dissolve.  The added benefit of Shell-O’s is that even if your snails don’t consume the whole O’s they will gradually breakdown adding calcium to your tank.
