Naturally occurring:

  • Algae: Mystery snails love biofilm and soft algae that grow on aquarium walls, plants, and décor. This is their primary natural food source, so a well-established tank will provide sustenance.


  • Sinking fish food pellets and algae wafers: Choose algae wafers or sinking pellets specifically for bottom feeders. They offer essential nutrients and help supplement the snails’ diet.
  • Blanched vegetables: Offer them a variety of blanched vegetables like zucchini, cucumber, spinach, kale, or carrots. Blanching removes harmful pesticides and softens the veggies for easier munching.
  • Calcium supplements: For strong shells, provide calcium-rich options like blanched spinach, kale, or a cuttlebone in the tank. You can also mix calcium carbonate powder with Repashy gel food to create “snello,” a snail-approved treat.

Things to avoid:

  • Copper: Mystery snails are super sensitive to copper, so be cautious with tap water that might contain copper traces. Consider using a water conditioner to remove it.
  • Acidic fruits: Opt for non-acidic fruits like grapes, melon, or pumpkin instead of oranges or tomatoes, which can harm the snails.
  • Overfeeding: While these guys love to eat, do what is necessary. Leftover food can decompose and harm water quality. Aim to feed them every other day or when all previous food is gone.

Bonus tips:

  • Variety is vital: Mix and match their food sources to ensure a well-rounded diet.
  • Target feeding: If you have other tank mates, use a clip or food dish to place snail food where they can access it easily.
  • Monitor water quality: Overfeeding or decaying food can impact water quality. Do regular water changes and clean up excess food to keep your snails happy and healthy.

Providing a diverse and calcium-rich diet will keep your Mystery snails thriving and your tank clean! Remember, a happy snail is busy munching away on algae and keeping your ecosystem balanced.

How Much and How Often to Feed Mystery Snails?

Mystery snails are omnivores and can eat various foods, including algae, vegetables, and fish. A balanced diet is essential to ensure their health and well-being.

There’s no one-size-fits-all answer to how much and how often to feed your mystery snails, as it depends on several factors:

Tank size and algae growth:

  • Snails might not need additional feeding beyond biofilm and leftover fish food in a well-established tank with ample algae growth.
  • Smaller tanks with limited algae require supplementary feeding every 2-3 days.

Snail size and activity:

  • Larger snails eat more than smaller ones. Adjust portions based on their size and activity level.
  • Snails might be less active and eat less during colder months.

Food type:

  • Different foods hold different nutritional values. Protein-rich foods like algae wafers can be offered less frequently than vegetables.
  • Be mindful of overfeeding with fatty foods like blanched zucchini.

Here’s a general guideline:

Feeding frequency:

  • 3-4 times a week: If your tank has limited algae or you have many snails.
  • Every other day: In well-established tanks with moderate algae growth.
  • Minimal or occasional: If the tank has abundant algae, they’re getting enough from biofilm and leftover fish food.

Food amount:

  • Start with a small amount and adjust based on how much they eat within 24 hours. Aim for them to finish the food overnight, leaving minimal leftovers.
  • Offer variety! Mystery snails enjoy algae wafers, blanched vegetables (zucchini, spinach, cucumber), sinking fish pellets, and even blanched romaine lettuce.

Pro tips:

  • Place food in different areas of the tank to encourage scavenging.
  • Avoid overfeeding, which can lead to poor water quality issues.
  • Ensure a balanced diet with both plant and protein sources.
  • Supplement calcium-rich foods like crushed cuttlebone for healthy shell growth.

By observing your snails and tank environment, you can fine-tune their feeding schedule and amount to keep them happy and healthy. Remember, it’s better to err on the side of less than overfeeding!

How To Feed Your Mystery Snails?

Mystery snails are herbivores and need a diet rich in plant matter. Offer them a variety of fresh vegetables such as zucchini, cucumber, and spinach.

Blanching or steaming the vegetables before feeding them to your snails is essential to make them easier to eat and digest.

You can supplement their diet with algae wafers and commercial snail food pellets. Provide a calcium source such as a cuttlebone or crushed eggshells to help keep their shells strong and healthy.

It’s best to feed your mystery snails small amounts of food at a time, as uneaten food can quickly degrade the water quality in their tank. Make sure to remove any uneaten food after a few hours.

Additionally, be mindful not to overfeed them, as this can lead to obesity and health issues. By offering a balanced diet and being attentive to their feeding habits, you can help keep your mystery snails happy and healthy. 

Tank Setup for Mystery Snail Feeding

Mystery snails are delightful little scavengers that are a joy to watch in any aquarium. Setting up a tank with their feeding in mind is vital to keeping them happy and healthy. Here’s what you’ll need:

Tank size:

  • Mystery snails need space to roam and graze. A 10-gallon tank is the minimum for one or two snails, but larger is always better. 

Water parameters:

  • Aim for a pH level between 7.0 and 7.5, ideal for their shell health.
  • Water temperature should be between 68°F and 84°F.
  • Keep the water hardness in the moderate range (8-18 dGH).


  • Choose a smooth, rounded gravel substrate. Avoid sharp-edged rocks or sand, which can damage their delicate bodies.
  • A depth of 2-3 inches of substrate is sufficient.


  • A good quality filter is essential for any aquarium and is even more important for a tank with snails. Snails produce a lot of waste, and a strong filter will help keep the water clean.
  • Choose a filter that is appropriate for your tank’s size and has a gentle current, as snails don’t like strong water flow.


  • Mystery snails love to climb and explore, so provide them with some hiding places and decorations. Rocks, driftwood, and live plants are all great options.
  • Live plants can also help to improve water quality and provide additional food for your snails. Choose hardy plants, such as Java moss, Anubias, and Amazon swords, that can tolerate being munched on.

Here are some additional tips for setting up a mystery snail tank:

  • Quarantine any new plants or fish before adding them to your tank. This will help to prevent the introduction of diseases.
  • Perform regular water changes to keep the water quality high. 10-25% water changes once a week are recommended.
  • Test your water regularly for pH, ammonia, nitrite, and nitrate. This will help you ensure that your snails live in a healthy environment.
  • Enjoy watching your snails! They are fascinating creatures to observe and can provide hours of entertainment.

With some care and planning, you can create a thriving tank that your aquatic snails will love. Monitor their behavior and adjust their feeding to keep them happy and healthy.

Why Are Mystery Snails Eating Live Plants?

Mystery snails are known to be herbivores, meaning they primarily feed on live plants. This behavior is natural for them, as they must consume plant matter to fulfill their nutritional needs. 

Mystery snails munching on your live aquarium plants can be a puzzling sight, but there are several potential reasons for this unexpected behavior:

Diet Deficiency:

  • Starvation: If your tank lacks sufficient algae, biofilm, or other food sources, hungry snails might nibble on live plants as a last resort.
  • Calcium shortage: Snails need calcium for their shells. While they primarily get it from water hardness, a deficiency could push them towards calcium-rich young leaves.

Plant Health:

  • Sickly or dying leaves: Mystery snails prefer softer, easier-to-digest food. They might target weak, decaying, or dying leaves on your plants for a quick snack.
  • New plant introduction: Newly introduced plants can be stressed and emit defensive chemicals that might attract aquatic snails looking for something different to eat.

Water Conditions:

  • Improper water parameters: Fluctuations in pH, hardness, or nitrite levels can stress plants and snails, potentially leading the snails to explore alternative food sources like live plants.
  • Nutrient imbalance: Deficiencies in essential nutrients like potassium, magnesium, or iron can weaken plants and make them more susceptible to snail munching.

Other Factors:

  • Species variation: Some mystery snail varieties, like the yellow ones, are known to be more plant-loving than others.
  • Competition: High stocking levels or competition for food from other tank inhabitants can also encourage snails to try new things like live plants.

Diagnosing the Cause:

Observe their behavior closely before concluding that your aquatic snails intentionally target healthy plants. Are they only nibbling on weak leaves? Are there other obvious signs of hunger or stress? Consider testing your water parameters and ensuring adequate calcium levels. If you suspect a dietary deficiency, supplement their food with blanched vegetables, algae wafers, or other snail-friendly treats.

By addressing the underlying reason for their plant munching, you can restore harmony to your aquarium and keep your plants and snails happy and healthy.
