What Do Aquarium Snails Eat?


Aquarists love aquarium snails because they keep the aquariums free of dead plants, extra fish food, and algae. What then do aquarium snails consume?

Algae, dead plant matter, scraps of fish food, bloodworms, brine shrimp, fruits, blanched vegetables, including lettuce, kale, and zucchini, as well as many other items are all consumed by aquarium snails. What aquarium snails eat is greatly influenced by their species, native environment, size, age, and specific dietary requirements.

Aquarium snails require a healthy setting and enough food to survive. Given that they can be either herbivores, carnivores, omnivores, or detritivores, snails have evolved to consume just about anything. Let's explore the precise diet of aquarium snails to ensure their continued growth.

What Do Freshwater Aquarium Snails Eat?

Most water tank snails are aggressive scavengers who don't have particular food preferences. They consume nearly anything that is easily accessible in the aquarium.

Aquarium snails are herbivores and like to eat algae, dead or rotting plants, organic waste, detritus, bacteria that grows on rocks and substrate, fish food, and other things they find in the tank water.

If you keep snails as pets, you can feed them a variety of foods, including fish pellets, algae tablets, raw or cooked kale, lettuce, blanched zucchini, cucumber, and commercial snail mixes that are sold in stores.

Your snails won't need much feeding if you have a tank loaded with live plants and algae because they will find food on their own.

In addition to their typical diet, carnivorous snails should also eat live prey like bloodworms, tiny brine shrimp, and feeder snails.

For best growth, they should be given a consistent supply of live prey once or twice a day.

Alright! Therefore, if we have an aquarium with fish and snails, we don't need to worry too much because the snails will eat the food that is sinking or that is left over.

However, since there won't be any leftover food easily available in a tank without any fish, you will need to feed your snails more frequently.

The following foods are suitable for feeding freshwater aquarium snails:

The main food source for snails is algae. In any tank with too much light and warm water, algae will grow. Your snails will clean away the algae in the tank if it is overgrown with it.


Fruits and Vegetables



Snails like to consume a variety of fruits and vegetables, including carrots, peas, lettuce, and other leafy vegetables. The vegetables need to be well cleaned and peeled. The hard veggies can then be blanched, cooled, and fed to your snails.


Similar to this, you may give your snails healthy fruits like watermelon, grapes, pumpkin, apples, and pears. To be avoided, though, are fruits with a high acid content, like tomatoes and oranges.

Some types of snails depend on aquatic plants to survive. The majority of snails, however, eat decayed or dying plant material. Apple snails will be content to eat live plants if you put aquarium plants there.


Commercial Snail Food


You can give your snails fish food made for bottom feeders, like sinking shrimp pellets. Since they are unable to consume fish food that is floating on the water's surface, snails prefer to ingest food that sinks. Additionally, they eat store-bought pills and wafers that are connected to the tank's side.

What Do Young Snails Eat?

Baby snails eat the same food as adult snails do.

Snail larvae that have just emerged feed initially on the small bacteria and algae found in the water. Baby snails kept in captivity can be fed cooked lettuce and kale.

Remember that young snails need to be fed more frequently than adults because they are still growing.

Young snails require a diet high in calcium for the development and robustness of their shells.

On rare occasions, you can give baby snails crushed eggshells, clamshells, or snail shells in addition to their regular meal.

Similar to adult snails, juvenile snails devour food like algae, plants, and debris once they have grown their shells and settled on the substrate.

How Frequently Should You Feed Snails?

Snails don't need to be fed frequently. You need to feed the snails every day or twice a week, depending on their species.

Be careful not to feed your snails too much. In about three minutes, you can feed them as much as they can consume.

It's important to give them fresh food each day and to eliminate any leftover food from the tank.

Because snails are nocturnal, you can feed them at night with foliage and fish food. You can adjust their diet up or down based on how hungry they are.

We've talked about a variety of feeds that are good for aquarium snails up to this point.

You must therefore be asking if there are certain things that aquarium snails should avoid eating.

What Should Snails Avoid Eating?

While snails don't have particular food preferences and generally eat anything, there are several items that should be avoided.

They shouldn't consume things like grapefruit, avocado, onions, lemons, parsley, celery, salt, and salty dishes.

Processed foods and foods with a lot of salt and sugar shouldn't be served to snails.

Even rice, millet, bread, pasta, and crackers should be avoided because they are difficult for snails to digest and might cause bloating.

For snails, salt is harmful because it burns the moisture from their bodies. This might potentially lead to their deaths.


What Do Nerite Snails Eat?

Herbivores include nerite snails. They enjoy eating the algae that grows on the tank's surface. You can give them blanched vegetables like spinach, cucumber, lettuce, or zucchini in addition to algae.


If your aquarium doesn't have enough algae, you can also give the nerite snails algae wafers to eat. You must, however, ensure that your snails consume all of the algae wafers and that none are left over. Unconsumed algae wafers degrade and contaminate the tank water, making it unfit for your snails to swim in.


What Do Ramshorn Snails Eat?

The majority of the time, ramshorn snails in aquariums consume soft algae, delicate plants, dead or decaying plant waste, uneaten fish food, dead fish, snails, or shrimp. Some species of ramshorn snails eat the stem plants' leaves.


Ramshorn snails can be fed fish flakes, pellets, algal wafers, and other calcium-rich foods. For their shells to develop healthily, calcium is essential.


What Do Apple Snails Eat?

Apple snails are well known for having a ravenous appetite and devouring plants. Apple snails in captivity consume a range of plants along with fish food. Additionally, they consume frozen food, dead fish and insects, living or dead plants, brine shrimp, and dead fish and insects.


Apple snails live in the wild and feed on plants, algae, fruits, vegetables, decomposing animals, microbe colonies, and the eggs of other snails.

What Do Mystery Snails Eat?


Mystery snails graze on algae that has accumulated on the aquarium glass, rocks, or sand, just like nerite snails do. The flora in your aquarium might serve as a food source for mystery snails if it is healthy. Additionally, the fallen leaves in your aquarium serve as a source of food.


Flakes, pellets, or blanched vegetables can be added to the diet of your mystery snails to enhance it and keep them healthy. Their ideal growth requires a calcium-rich diet. Because they are opportunistic scavengers, mystery snails consume a wide range of foods.


They consume anything that is found in the wild, including dead fish, shrimp, debris, animal carrion, algae, and decaying plant stuff.
