Stomatella Snail Tank Requirements

When setting up an aquarium, we recommend keeping some algae to make an ideal habitat for your Stomatella snails, which love to eat algae.

Also, it is wise to keep ample rocks,  live rocks,  rock caves, and corals. Thanks to that, your snails will have a couple of hiding places.

Proper Required Tank Size

Ideally, set aside a 90L (20 gallons) aquarium to house one to five snails. Avoid keeping more than five snails in a twenty-gallon aquarium.

If you want to increase the number of your Stomatella snails in your tank, adding five gallons to each snail is best.

Water Quality

Maintaining a lower nitrate aquatic environment is ideal for these tiny and helpful snails. Also, ensure the calcium & magnesium levels in the water are stable so they can live happily.

Most snails, including Stomatella snails, are susceptible to copper. Copper may even kill these snails.

So avoid using medications that contain copper in a Stomatella snail tank.

On the flip side, maintaining the water’s cleanliness is essential. You should also know that these snails can be sensitive to a change in salinity.

For Stomatella snails to acclimate to a new home, it is okay to apply a slow drip acclimation method which takes about two hours or more.

Water Temperature

Maintaining the water temperature from 50 to 75 degrees F is okay.

We recommend installing one aquarium heater inside the tank, allowing you to adjust your tank’s internal temperature easily.

PH Level

The pH of the water in your tank should be between 8 and 8.4.


These tiny snails belong to the family of nocturnal creatures which do not require high-light conditions.

But installing moderate, low lights in the tank where your snail lives is okay.

In the night environment, when they thrive, using a flashlight to track the movements of these animals is alright.

Water Gravity

The ideal salinity value for the water in your aquarium ranges from 1,023 to 1,025.

That salinity value equals 35 ppt, which you get by using 35 aquarium salt grams per water gallon.

Water Hardness

You should make sure your aquarium has a calcium level of 380 to 450 mg/l, compared to 420 mg/l for natural seawater.

Keeping the water with a stable calcium level will create a happy environment for Stomatella snails.

Moreover, it is wise to maintain the hardness of water ranging from 8 to 12 dKH.
