Calcium Deficiency

What’s the deal with calcium?

One potential culprit behind the white spots on your Nerite snail’s shell is calcium deficiency. Calcium is an essential element for snails, as it plays a significant role in shell development and overall health. Insufficient calcium in the tank may lead to weak shells, making them more prone to breakage and white spots.

Boosting Calcium Levels

To avoid calcium deficiency, ensure the water in the aquarium has the right balance of hardness and alkalinity. You can easily maintain and monitor calcium levels by:
– Testing the water regularly,
– Adding crushed coral, aragonite sand, or limestone,
– Supplementing with calcium products like calcium chloride or calcium gluconate.

Water Parameters

Getting the Balance Right

Improper water parameters can create an imbalance in your aquarium, which may also contribute to white spots on Nerite snail shells. Factors such as pH, temperature, and chemical content can greatly impact snail health.

Water Quality Matters

Safeguard your snails’ shells by maintaining quality water conditions. Here’s what to consider:
– Keep pH levels between 7.5 and 8.5
– Maintain stable water temperature between 72°F and 78°F
– Regularly test the water and adjust parameters if necessary
– Conduct routine water changes to keep the environment clean

Damage from Tank Mates

Bad Neighbors

Sometimes, the cause of your snail’s white spots might be as simple as a squabble with another tank inhabitant. Aggressive or territorial fish can inflict damage on the snails’ shells.

Peaceful Coexistence

To prevent damage from tank mates, ensure you house your Nerite snails with compatible species. Peaceful tank mates include:
– Small community fish
– Other peaceful snails
– Shrimps

Shell Erosion

Why Erosion Occurs

Another possibility for the appearance of white spots may be shell erosion, which occurs when the snail’s shell gradually breaks down over time. Acidic water, aging, or even bacterial infections can contribute to shell erosion.
