Aquarium snails usually do not escape unless the tank is not properly maintained. Bad tank conditions, unfavorable water parameters, aggressive tank mates and overcrowded tanks are some of the reasons why snails try to escape. A suitable tank environment is key for aquarium snails to thrive.
It is typical ofsome snail specieslike Nerite snails to escape the tank out of curiosity. They do this to explore the environment around them. However,stay out of the tankfor an extended period of time is not a good sign as aquarium snails need to stay moist to survive. So you have to give your snails the best possible environment. Having said that, let's now examine in detail the possible reasons why aquarium snails escape.
Why do aquarium snails escape?
Below are the main reasons why aquarium snails try to escape:
1. Poor tank conditions.
Each creature has specific needs to grow and prosper. Suitable habitat is what every pet is looking for to live a happy and long life.
Snails also need favorable tank conditions to live as they spend their entire lives in the home aquarium.
Snails cannot tolerate poisonous water. It harms them a lot and makes them sick. High levels of ammonia, nitrates and nitrites suffocate the snails.
Unlike fish, which have no choice but to live in the poor habitat, snails will try to crawl out.
If the tank water is polluted, snails will no longer live in that environment and try to escape the poor habitat.
2. Unfavorable water parameters.
Different types of snails have different needs for water parameters and temperature.
If the water parameters and temperature are not suitable for the snails, they will escape from the aquarium.
In addition, the water temperature must also be stable.
So if you have a low quality heater that results in water temperature fluctuations, the snails will be distressed and try to escape the tank.
Another point to consider is the water hardness. Snails need enough calcium for the healthy development of their shells.
So if your aquarium water is soft and acidic, it will damage the snail shells, causing them to dissolve.
All these factors should be closely monitored. Otherwise, the snails will be forced to escape from the aquarium.
3. Overcrowding.
Overcrowding is also one of the main reasons for aquarium snails to escape from the aquarium.
An overcrowded aquarium prevents the snails from moving freely and suffocates them.
The limited space makes the snails anxious and they may try to escape from the aquarium.
Tanks should not be overcrowded with fish and other snails. Yes, even too many snails in a single tank cause them stress and anxiety.
Another reason that can force the snails to escape is the scarcity of food.
Too many snails in an aquarium will result in less algae, resulting in a food shortage.
If the snails are hungry and cannot find food in the aquarium, they will try to escape in search of food.
Additionally, if the tank is overcrowded, whether with excessive tank mates or plants, the snails will escape in search of a more suitable environment.
4. Aggressive roommates.
Aquarium snails are usually peaceful creatures. They generally do not get in the way of their fellow residents and like to live in harmony.
Snails do not irritate their fellow inhabitants. So keeping your peaceful snails with aggressive co-inhabitants will make the snails' lives miserable.
The snails will then try to escape from the aquarium.
5. Insufficient food.
Hunger or lack of food is another reason for snails to escape from the aquarium. Snails are known for their ability to eat algae.
You will find your snails happily chewing on the algae that has formed on the aquarium decorations. Snails also scrape any algae off the plants.
So if the algae in your tank is less and you are not feeding the snails satisfactorily, they will look for alternative food sources.
If the snails do not find food around them, they will try to escape the aquarium in search of food.
6. Unsuitable surface.
Snails don't like rockyn, especially Nerite snails.
This is because their underbody is delicate and having a substrate with sharp edges can injure the snails.
Also, if you have decorations in the aquarium with rough and penetrating parts, they can damage the snails.
In that case, the snails will try to escape the aquarium in search of a comfortable place.
Agree! Now that you know the possible reasons why aquarium snails escape, let's also discuss the ways to prevent snails from escaping.
How do you prevent aquarium snails from escaping?
Snails are considered escape artists because they find numerous ways to escape from the tank.
So you must be vigilant. Snails are better off in the water because their chances of survival are higher in the water.
Therefore, it is advisable to solve the problems that prompt snails to escape from the aquarium.
It's not hard to keep snails happy. You can follow the methods below to prevent snails from escaping.
1. Be knowledgeable about snail species.
Snails belong to one of the largest classes of organisms. There are many recognized snail species, divided into marine and freshwater snails.
So you must have sufficient knowledge about the natural habitat and water needs of your pet snail species.
For example, Nerite snails thrive in brackish water, as their natural habitat is salt and brackish water.
So it is better if you know in advance whether your snails are freshwater or seawater. This will help you set up a suitable environment for the snails.
In return, the snails will not try to escape the aquarium in search of a better living environment.
2. Create a favorable environment.
A favorable living environment is a prerequisite for snails to live a long and healthy life.
Snails will not escape from the aquarium if you improve their living conditions.
A favorable environment includes suitable water hardness, clean and non-toxic water quality, suitable water temperature and correct pH values.
Your aquarium water should not contain substances such as ammonia and nitrites, decaying organic matter, fish or snail waste and leftover food.
Water hardness is another factor that should not be overlooked.
Snails need calcium to develop their shells. Therefore, they prefer hard water rich in calcium.
You can use limestone and crushed coral to increase water hardness.
In addition, you can add calcium supplements to your tank water if you notice signs of wear and tear on the snail shells.
3. Maintain proper water parameters.
Maintaining proper water parameters is another way to prevent snails from escaping.
If you provide a suitable water temperature and pH level, snails will be happy and not try to escape.
The ideal water temperature for freshwater snails ranges from 72°F to 82°F. The ideal pH level is anything in the range of 7 to 8.
You should also make sure your tank water does not contain copper, as it is deadly to snails.
4. Avoid aggressive roommates.
Snails are peaceful creatures and like to creep into their own territory. Therefore, you should avoid keeping aggressive or large fish that could stress the snails.
Aggressive and large fish bully and even eat the snails. So it is better not to keep them as co-residents.
If you don't want your snails to escape, pair them with equally peaceful and small creatures such as guppies, tetras, and shrimp.
5. Avoid overcrowding.
Like fish, snails need enough space to live. So you should avoid overfilling the tank as this will lead to space constraints.
Your aquarium should ideally be spacious so that snails can live happily.
Besides, if you have a larger and less crowded tank, your snails will have plenty of room to crawl and explore the tank.
They don't have to escape out of curiosity or climb out of the tank.
6. Provide a suitable surface.
A suitable substrate is another way to prevent snails from escaping. As you saw earlier, snails get hurt when the substrate has sharp or rough edges.
Alternatively, you can cover the bottom of your aquarium with a sand substrate.
This will keep the snails from getting hurt. They can easily crawl on the delicate sand without fear of getting hurt.
If you opt for gravel in your container, you can opt for gravel with rounded corners.
Also, the tank decorations should not have sharp edges.
7. Provide enough food.
Most of thesnails are mainly algae eaters.
So if you notice that there is not enough algae growth in the aquarium, you should provide the snails with enough varied food.
You can feed the snails, blanched veggies, carrots, zucchini, and even algae wafers.
Since snails are voracious eaters, they need food to chew.
So the best and easiest way to prevent snails from escaping the aquarium is to provide them with a stable food source.
8. Maintain the water level and close the tank lids.
Another way to prevent snails from escaping the aquarium is to maintain the water level.
You shouldn't fill your tank to the brim. You can keep the water level a few inches below the top.
This ensures that the snails do not escape in search of a dry spot.
You can also put a lid on the top of your tank.
The lid not only covers your aquarium, but also helps to keep the water clean.
However, the lid should not be airtight. Otherwise, gas exchange will not go smoothly and your snails will suffer.
Also, make sure there is no gap in the lid for the snails to escape. Otherwise, the lid will not serve its purpose.
Some aquarists apply products such as petroleum jelly to the tops of the tank to make them slippery.
The snails can then no longer climb out of the aquarium. However, this is not a good approach. It should be your last option if nothing works.
