I am an aquarist, and I love decorating my fish tank now and then, so I buy a lot of aquarium decorations now and then. Whenever I get something new for my little aquarium, I see many snails emerging in my tank.

It made me question myself. Where do these pest snails come from, and how to get rid of snails in aquariums?

Where Do Snails In The Aquarium Come From? 

Snails are unwelcome guests that can sneak into your beautiful fish tanks via decorations, plants, or the water that your new fish comes in.

They enter your tanks mainly in the form of tiny eggs and cannot be adequately seen with the human eye. Once they have entered, it will only take one snail to create a hundred more and expand quickly.

Snails are cute creatures, but too many of them in your aquarium will only bring trouble. They may harm your fish, destroy your tank or finish your fish food. It is always better to get rid of them as soon as possible.

10 Ways To Get Rid of Snails In Aquarium

Snail eggs can make your life difficult once they enter yours. Do you want to know how to get rid of snails in a fish tank? Here are a few options to make your aquarium a better place for your fish.

#1- Poison

How to get rid of snail infestation in aquarium? Get some snail poison. Snail-killing poison is available on the market, which kills snails, eggs, and other insects or invertebrates present in the tank too. It is very effective but should be used in small amounts as it may harm the fish in your aquarium.

Using this poison in your tank where there are a lot of snails is not a good idea. The dead snails might be poisonous to other aquatic friends present in the tank. So it is better to opt for other options first.

#6- Less Food

Stop overfeeding your fish because, most probably, the pest snails are devouring all the fish food you are adding to your tank. Just add the amount that would suffice your fish’s need instead of adding it in extra quantity.

#7- Snail Trap

In this guide on how to get rid of aquarium snails, I would suggest you invest in snail traps. You can get them from pet shops or buy them online. They are mostly made of plastic, and you will need to secure them on the sides of your tank.

Are you not investing in a snail trap? That is entirely okay. Use vegetables as baits instead, and the process is straightforward. Some snails like to hide deep in your aquarium tanks, but you can catch them with lettuce.
