Cleaning nerite snails aquatic stem plants

Are underwater snails strictly bound to "under" water?

I recently bought a small aquarium and stocked it with live plants to create a natural environment.

I haven't filled the tank with fish at the moment, but I've noticed some tiny snails. They must have been attached to the plants and I'll be fine with them now. What worries me a little is whether these snails out survive the water? I'm just watching one move closer and closer to the top of the tank where there is a little gap that air lines etc. can pass through.

Is it likely that these snails will venture out of the water into my room and survive to tell the story?

Can snails found in aquariums survive without water?

Update: snail breaks the water.

The snails do not survive long without water. Hours at most. If they don't come into contact with water, they dry out and die. I am afraid I cannot find a source. My nerite snails regularly sit a little above the waterline, but are still damp from the water.


It depends on the snail. Some can survive without water for days, if not weeks. The same goes for the eggs they lay, but it depends on the species. I'm just saying slugs are generally considered a pest, unless they're a non-malignant variety like Nerite, which is unable to reproduce in a home aquarium. This is subjective, but I strongly recommend checking and removing them now rather than later. They can become a big problem.


@Jestep how would you suggest doing this? I wanted to get some loaches when I have the tank in stock (soon) and I think they are very fond of snails?


@WasabePeas Don't worry about the snails. Usually, they cannot really be avoided and they are just a little more visible in a balanced aquarium. We need a better picture of the snails to identify them. If you don't overfeed your fish, the snail population should control itself and stay at healthy levels while removing excess food and algae for you. I wouldn't try to get rid of it.


@Mario they are really tiny right now so I don't think I could get a good quality photo. If they get bigger and become a problem, I will definitely post a photo!


What I have gathered from analyzing the comments is that bladder snails (identified as the species in question) can go above the waterline along with other species, however usually return to the water by itself.

From what I've found elsewhere on the internet, they do this to feed or lay eggs, or just to get out of the water when the quality is particularly poor (more likely when all Snails out of the water are what it seems at the moment). Another reason I found is that some species of water snails use the lungs to breathe - and that's why they just go to the surface to do so!

But generally speaking, the snails return to the water on their own!
