Easy Steps To Get Rid of Snails in Aquarium

Do you know the easy steps to get rid of snails in Aquarium? Aquarium enthusiasts often encounter the challenge of managing unwanted snail populations that can rapidly multiply and disrupt the delicate balance of their aquatic ecosystems.

Generally, snails are not exactly bad but when you have an invasive species of snails that could rapidly multiply in a very short time, it becomes a big problem for the aquarium as well as its originally intended occupants.

Some aquarium owners of their own accord introduce snails into their aquariums, while some just wake up only to discover the presence of snails. Whichever group you find yourself in and wish to solve the problem quickly there’s a solution.


10 Easy Steps To Get Rid of Snails in Aquarium

While some snail species are beneficial, others can become pests. The major problem with snails in your aquarium irrespective of whether they’re beneficial snails or pests, is that they can overpopulate your aquarium placing a burden on biological filtration.

A few snails aren’t a problem but hundreds and sometimes thousands of little snails are a source of major concern to every aquarium enthusiast.

In this comprehensive guide, we’ll delve into the steps you can take to effectively and responsibly get rid of snails in your aquarium, ensuring a healthy and harmonious environment for your aquatic inhabitants.

These informative steps I culled from the numerous articles by the national park aquarium that go deep into teaching one how to manage and maintain a healthy aquarium for their plants, fish, and other aquatic pets.

Without any further ado, let’s get to the detailed steps.


1. Identification and Assessment

The first step in managing snail populations is identifying the types of snails present in your aquarium. Understanding whether snails are beneficial or pest species will guide your approach.

For instance, Malaysian trumpet snails help aerate the substrate, while pest snails like bladder snails and pond snails can proliferate rapidly. Assess the population size to determine the severity of the issue and decide on appropriate action.


2. Manual Removal

Start by manually removing snails. A small net or a homemade snail trap can be effective tools. Gently scoop out snails from the water, being thorough in your efforts to prevent any from escaping. While manual removal is labor-intensive, it’s a crucial step to immediately reduce the snail population. The application of manual removal can also ensure you keep an eye on your aquarium to notice if anything else is wrong.


3. Reducing Feeding

Snails feed on uneaten food and organic matter, so controlling their food source is essential. Be mindful of your feeding regimen and avoid overfeeding your fish. By feeding only what your fish can consume within a few minutes, you’ll minimize excess food that snails thrive on.

Any leftover food that was not eaten by your fish is an invitation or an encouragement for any snails lurking around in the aquarium. You want to discourage their presence by starving them.


4. Introducing Predators

Introducing natural snail predators is an ecological approach to controlling snail populations. Certain fish species, such as loaches and pufferfish, as well as assassin snails, are known for their appetite for pest snails.

However, ensure that the predator species are compatible with your existing aquatic inhabitants to maintain a balanced ecosystem. You don’t want to introduce predators that would end up feeding on your fish as well as the snails. You need to introduce predators that would have no negative impact on your existing fish.


5. Chemical Treatments

Chemical treatments are a last-resort option and should be approached with caution. Copper-based medications and snail-killing products can eliminate snails, but they can also harm other aquatic life and disrupt the overall balance of the aquarium.

If considering this method, carefully follow product instructions and remove treated water after the specified treatment period.


6. Manual Control Methods

Manual control methods are not the same as the manual removal method that’s mentioned above. The manual control method involves the use of extra baits and traps to attract the snails and take them out at the right time. There are a couple of manual control methods that can aid in snail removal, consider the ones below:

  • Blanched Vegetables: Placing blanched lettuce or cucumber in the tank overnight attracts snails. In the morning, you can remove the baited food along with the snails that have gathered.
  • Snail Traps: Crafting a simple snail trap involves placing a piece of food inside a container with small holes. Snails enter the trap for food but can’t escape.


7. Regular Maintenance

Maintaining a consistent cleaning routine is essential to prevent future snail infestations. Regular substrate vacuuming, the removal of uneaten food, and scheduled water changes help keep the aquarium clean and reduce the organic matter that snails feed on.


8. Quarantine New Aquarium Additions

New plants, decorations, and fish can introduce snails to your aquarium. Thoroughly inspect these additions for snails and their eggs before introducing them to the main tank. Quarantine new additions in a separate tank for observation to prevent potential infestations.


9. Patience and Persistence

Successfully managing snail populations requires patience and persistence, especially if the population has grown significantly. Consistency in your efforts and a proactive approach will ultimately yield long-term success.


10. Prevention

Preventing snail infestations is key to maintaining a balanced aquarium. Practicing proper aquarium hygiene, avoiding overfeeding, and carefully monitoring new additions are effective preventative measures. By maintaining a healthy ecosystem, you reduce the likelihood of snail overpopulation.



Managing unwanted guests in your aquarium demands careful consideration, observation, and action. Especially when these unwanted guests are snails. Whether through manual removal, introducing predators, or employing preventative measures, it’s possible to achieve a snail-free or controlled environment.

The key is striking a balance between maintaining the health of your aquatic inhabitants and preserving the equilibrium of your aquarium ecosystem. By following these above-listed steps and adapting them to your unique situation, you can ensure a thriving and harmonious underwater world for your pets.
