What Do Freshwater Snails Eat: Foods That Are Safe for Your Snails

Freshwater snails eat algae, plants, and small invertebrates, and a varied diet is essential to ensure their well-being. Some food items to avoid for freshwater snails include fish pellets, dead plant matter, and food scraps. 

In addition, freshwater aquatic snails need some water movement to eat and live. You can provide them with a small water fountain or aquarium pump to help with this.

What Freshwater Snails Eat


Freshwater snails eat algae. This is beneficial because it helps to remove unwanted plant material from your water aquarium or pond. If you see large amounts of algae on the surface of your water, it’s probably because they’ve eaten a lot of it. 

However, freshwater snails are not algae eaters exclusively – they will eat other types of aquatic plants too. So, it’s essential to watch snail populations and keep them free from food that would kill them if ingested – like fish flakes and dead animals. 


Yes, freshwater snails eat fish! So if you find fish food in your pond or aquarium, there’s a good chance freshwater snails are dining on it.


It is unclear whether freshwater snails eat tadpoles, but they may. If you see tadpoles in your garden or pond, it might be a good time to get rid of them before they become dinner for the snails.

Some people think freshwater snails eat frogspawn, but this is still unconfirmed. What is known is that freshwater snails eat plant matter, algae, and other aquatic invertebrates.

Blanket Weed

Freshwater snails eat loads of plant matter, including blanket weed. However, this isn’t the only thing they eat. Other things freshwater snails scavenge include dead leaves and flowers. 

So, if you see snail trails in your garden and there are no signs of damage, it’s safe to leave them be. So if you’re worried snail trails might mean your snails are eating something wrong, keep an eye on your garden for snail trails – this is a sign they’re eating something! 

Water Lilies

Snails eat water lily pods, but it is unclear if they eat water lilies. If you’re concerned about your water lily being eaten, you can take a few steps to protect it. 

Regularly spray the plant with insecticide to kill any snails that may be present. Also, install a snail barrier to keep them out – this will help to prevent them from scavenging food from the plant surface or consuming small pieces of leaf tissue. 


Freshwater snails eat duckweed, so it’s essential to provide them with this plant if you want them to eat food other than algae. Duckweed is a popular food for water snails; they will eat it as a primary food source. If you see snail trails in your garden or pond, there may be duckweed nearby that the snails are eating!

Mosquito Larvae

Freshwater snails eat mosquito larvae and other aquatic invertebrates, which helps to keep their populations under control. However, freshwater snails are only sometimes enough to control mosquito populations on their own.

Keep an eye on the number of mosquitoes around your property, and adjust your snail food strategy as needed. For example, if you’re experiencing many mosquito problems, it might be time to add freshwater snails to your pest control arsenal!


Freshwater snails eat apples. However, snail populations can also damage apple trees, so check on them and remove dead apples if you see them. 


Freshwater snails eat just about anything, but they are especially fond of carrots. So, if you want your garden to be snail free, keep carrots out of reach!

Other Snails

Freshwater snails also eat other snails. If you’re still unsure if they are safe in your home, water snails eat a variety of food, so you can be sure they will be okay.
