We initially noticed people worrying about any potential side effects with their aquatic snails due to treatments like Melafix after publishing our article going over if Melafix will hurt healthy fish or not.

This is why we have decided to publish this article going over why we, and a huge number of fish keepers do consider Melafix to be safe for use in aquariums with a huge range of species of aquatic snails.

Is Melafix Safe For Snails?

Melafix is perfectly fine for use in tanks with snails due to Melafix using tea tree extract as its active ingredient within the formula that has a minimal effect on aquatic snails.

This ensures that your snails and other invertebrates should be perfectly fine in your aquarium while you use treatments such as Melafix to treat problems with your fish.

This is why Melafix has such an excellent reputation amongst the fish keeping community due to being such an effective treatment that is also very safe for the other inhabitants of your tank.

Are There Any Side Effects of Using Melafix In Tanks With Snails?

Although it is highly likely that you will not have any problems with your aquatic snails when using Melafix in your tank, there is one thing you have to consider, injured snails.

Snails that have a cracked or damage shell can be at a small risk of having a reaction to Melafix in their tank but this is not considered an issue for healthy snails.

We go into this in more detail in our article on what to do with a snail that has a cracked shell but the short version is that aquatic snails are considerably more vulnerable if their snail is cracked.

This allows the Melafix to get to areas of your aquatic snails that it wouldn’t usually be able to get to and potentially cause a reaction with your snail.

That said though, there are reports of people who have snails with various infections actually being able to treat the infection with treatments such as Melafix and Pimafix so there is always a trade-off.

Provided that you follow the correct dosing instructions on the label of your Melafix for your tanks water volume, you shouldn’t have any serious problems with your aquatic snails.

Ideally, you will be quarantining your pet fish that has the problem requiring the use of Melafix into its own tank anyway to reduce the risk of the problem spreading to the other fish that you keep in your tank with this also removing any potential risk to your snails too.
