Egg shells for breakfast?

    I put some egg shells cleaned with aquarium water in the tank for my snails and now all three of them are on the shells? Is this normal behavior for snails? Is that how they get their calcium?

    Hello Jackie. I've never seen my snails actually eat the egg shell but they do climb on it. The shell dissolves and adds calcium to the water. Too get the calcium into the snail I feed zucchini...high in calcium.
