What Is The Best Snail For An Aquarium?

Most aquatic snails are great additions to any aquarium. When looking for the best snail for your aquarium, you need to consider water conditions, tank size, and the other creatures living in the tank.

The majority of aquarium snails play an important role in your tank. They will feed on algae, dead plants, and leftover fish food, keeping the water clean and clear for your favorite fish.

What is The Largest Aquarium Snail?

Most snails will only reach around 2-3inches max in most aquariums. However, the Giant Sulawesi snails can grow to around 4-inches long. 

These snails need plenty of room in the aquarium, so getting an extra-large tank or adding fewer plants and accessories is best. These are hardy creatures and can live in many types of aquatic environments. 

Can Snails Kill Fish?

The average aquarium snail will not eat a healthy, alive fish. They will, however, feed off of the dead ones.

You may also notice your snails nibbling on dying or weakfish as well.  That is because they have easy access to the dead skin as these fish will not be moving around. 

Is Snail Poop Bad For An Aquarium?

Snail poop can make your tank quite dirty and will require you to clean it every so often. However, on the other hand, snail poop can also be beneficial to your aquarium.

Having a few snails pooping in a tank of plants can actually fertilize these plants, keeping them healthy and alive longer. 


There are many benefits to having aquarium snails co-existing inside your tank, whether it is with fish, other snails, or even just aquatic plants. They are great for keeping algae at bay and cleaning up the tank from leftover food and rotting plant debris.

Snails can add an array of vibrant colors and decorative looks to any aquarium and are relatively easy to care for, not looking for much maintenance or attention.
