|Tank mates / Compatibility:||These peaceful creatures will not harm anything, so will be a happy tankmate for any other creature, providing their companion doesn’t have an appetite for it.|
From South America, and native to Bolivia, Paraguay, Peru, and Brazil, you’ll find mystery snails in slow-moving water environments. You can also find non-native populations in Southeast Asia, but this is a lot rarer.
They are an extremely popular addition to most household freshwater tanks, so you certainly won’t be alone in keeping mystery snails.
The primary reason they are so popular is for their tank-cleaning abilities, as they eat algae and other greens. Therefore, sit back, relax, and enjoy, as your new addition does all the cleaning work!
What Does a Mystery Snail Look Like?
They are commonly known for their bright yellow shell, but come in darker colors as well, like blue or black. In fact, it comes in a vast range of colors, so it can provide a burst of vibrancy for your aquarium.
The shell patterns can depend on environmental factors, so its environmental history can be recognized via its color patterns. Its shell can also be damaged by the environment—for example, too little calcium, or too high acidity, can erode it. Therefore, you can really tell a lot by this creature’s looks.
The golden mystery snail grows to around two inches in diameter, so will not steal too much tank space. It has a little tube called a siphon on its body, which extends above the waterline for oxygen. Despite this, it is essential to provide the snail some above-water space to relax.
Of course, eyes are an important feature of mammals, and the mystery snail certainly has some of its own. These are used to sense motion and light. However, these creatures rely mostly on their tentacles to suss out their living quarters.
They have two sets of tentacles on their head, one for feeding, and one for sensing its surroundings. Have you ever noticed when you go near a land snail, and it tucks its little antennae in? This freshwater snail will do the same when it senses a potential predator, alongside retreating into its shell for safety.
One thing to note is that mystery snails are not hermaphroditic like most snails. That being said, there are some notable differences between the two sexes. These include:
- Size: females tend to grow faster than males.
- Shell shape: male shells have a larger, rounder opening.
- Genitalia: the male will have a visible penial complex in its opening.
How Hard is Mystery Snail Care?
Mystery snail care is simple, they are very easy to look after, thriving on a mainly vegetarian diet but, upon seeing a dead fish, may enjoy this as a meaty treat. Though generally, these slimy creatures are like cows and graze around the tank gradually.
Their bright colored shells are quite a spectacle, and will certainly brighten up any tank space.
Nevertheless, the shell very much depends on the environment to remain healthy: once damaged, it will not heal. Therefore, it’s important to keep an eye on their living space to maintain your little friend.
These creatures are perfect for any tank owner who already has fish and simply wants another mate to join the crew. Due to their laid-back and chilled character, mystery snail care requirements are minimal, so they also make a great first-time pet.
What are Their Natural Behaviors?
The peaceful and calm mystery snail really is no trouble. They spend most of their time grazing around the tank, eating any stray algae they may find. They’ll make a friendly neighbor for almost any other freshwater dwellers unless they present a danger to our shelled friends.
As noted before, if a predator approaches, the mystery snail will retreat into its shell for protection. However, it’s best to ensure it’s not joined by any invertebrate eaters, as it may become a tasty dinner.
In general, it’s just important to ensure it is comfortable in its surroundings and isn’t frightened by its tank mates.
Additionally, they will happily explore the tank, but needs a space to sit above land for oxygen when needed. Without this, it may struggle to stretch its siphon above the waterline and may become deprived and die.
Ultimately, they are very docile, requiring minimal care to remain happy; certainly a fantastic start for a beginner.
What are their Ideal Tank Requirements and Habitat?
In their native habitat in South America, these peaceful gastropods typically live in swampy and slow-moving waters.
As long as the water remains relatively calm, these snails will thrive without being washed away. They will usually remain on the bottom, but can sometimes also be found hiding among decomposing plants.
What Water Type and Temperature do They Prefer?
When it comes to water conditions, they are a freshwater fish who thrive in an ideal water temperature between 68 and 84 degrees Fahrenheit.
When it comes to water quality, it should be above a pH of 7.0, but preferably remaining between pH of 7.6 to 8.4.
The water should also be a KH of 12-18. This will help keep their shells healthy and ensure they aren’t dissolved, leaving them open to predators.
Also keep in mind that moderate water movement is necessary. It’s best to replicate slow-moving environments for them, which isn’t difficult in a tank with a filter that generates a current from the water return outlet.
What Tank Size do They Need – Gallons Per Mystery Snail?
The water level should remain relatively low for these oxygen-breathing snails, allowing them to reach water surface level without too much trouble.
In general, five gallons of water for every one or two snails is sufficient, but 10 gallons is generally preferred.
Regardless of this, they will roam around the tank, so keeping a tight-fitting lid is essential.
What is a Suitable Substrate?
As they remain mainly on the ground, adding pebbles or sand can really aid their ease of movement, but they are happy with almost anything.
So choosing your ground material will just depend on any other creatures residing in your tank.
What Filters Should You Use?
One big issue with mystery snails is they can get their head stuck in regular water filter slots. This can cause them major stress, their head may swell, and they might die.
Therefore, to avoid this, it’s best to purchase sponge pre-filters instead of stronger ones, or if you have a strong filter to add some sort of baffle or mesh to the water inlet.
A baffle is the preferred method, rather than a weaker filter, else you will have to perform more frequent water changes.
Do They Have any Preferential Lighting Needs?
They are rather sensitive to light, so a darker environment is preferable. They tend to be a lot more active during the night, as they thrive in the dark. Just avoid bright lights and strong daylight to ensure their comfort.
What Plants Should You Decorate Your Tank With?
What makes them particularly happy is if their tank is kept relatively green to cater to their grazing appetites. This will mimic the green bottoms of any pond, river, or swamp it would naturally reside in.
Furthermore, the vegetation will exert more oxygen into the environment; ideal for these oxygen-dependent creatures.
So rather than just pick out a live plant or three to recommend, we’ll say – just get some in there! Any that will be able to share and thrive in the same water conditions.
Otherwise, as mentioned before, they appreciate areas to perch on during the day. Large and sturdy plants, for example, Java ferns or moss, are great for this pastime.
What do They Like to Eat?
Being omnivores, they will happily remain on a diet of vegetation, including algae and leafy greens, like lettuce. They are very opportunistic, however, and will snack on dead animals or decomposing plants when available.
If you feed commercial pellets, algae wafers should be what you strive for. These will have most of the nutrients they need, and mimic what they would mostly eat in the wild. However, algae wafers can never replace the real thing…which is OK, as they will graze the fresh algae that grows in your tank.
Generally, they are really easy to feed, requiring minimal effort.
What do They Eat in Their Natural Habitat?
Generally, they will eat whatever they can find, but they favor algae which accumulate on plants and stones, as well as eating the odd leaf off live plants.
They also have no issue with digging a little to find more algae under the rocks.
What Should I Feed Mystery Snails at Home?
In general, they will gradually make their way around the aquarium glass, munching on algae as it goes.
That being said, food supplements, such as bottom-feeder pellets and algae wafers make a great food source for them.
Are There Human Foods They Can Eat?
As discussed previously, these snails very much enjoy leafy vegetables. Lettuce and zucchini work well, but it’s important to blanch the food to soften it before eating.
How Often Should You Feed Your Mystery Snails?
In general, feed your snail as much as it will consume in one to three minutes, twice a day. Otherwise, they will simply graze throughout the day.
Golden mystery snails don’t need much sustenance, so it’s good to just experiment, as they are all different.
During colder months, they will need more food to sustain their energy, but trial and error will work well. Give them a few food items per day, and see how quickly it disappears.
Any Special Care Requirements?
With all aquarium freshwater snails shell care is important, so the water environment needs to be monitored to ensure a long and healthy lifespan. Some elements to watch out for are:
- Low salt levels: the snail thrives in freshwater, with an aversion to salt.
- Low copper levels: too high, and you’ll kill this majestic shelled creature.
- Temperature: too high, and it will die sooner.
- High pH: must be above 7.0. (Check out our guide to lowering or raising pH if needed.)
- High calcium levels: without this, its shell will dissolve.
In order to combat these environmental factors to ensure optimum mystery snail care, follow these suggestions:
- Purchase calcium supplements to keep their shell strong.
- Do not add any copper-based water treatments to their habitat.
- Add a pH and temperature gauge to keep an eye on the water.
Just monitor their shell, as this is a good tell-tale sign of their surroundings. In general, if it begins to erode, this is not great, and adjustments should quickly be made.
Otherwise, these snails can be prone to rat lungworm, although this is more common in the wild. Therefore, it is just its shell you should really watch out for.
Mystery snails are extremely friendly, so many freshwater fish species can be tank mates alongside them.
Just remember that the tank environment is very important to keep the snail’s shell healthy. Therefore, creatures that need a similar environment and water conditions will make the best neighbors for our snails.
You can consider keeping tetras, killifish, guppies, as well as amazon or cherry shrimp. You can also keep other freshwater snails such as ramshorn or nerite snails.
But of course, stay away from any fish that may consider them part of their diet! These tend to be large predators such as oscar fish and cichlids, which should never be in the same tank.
How Many Mystery Snails Can Be Kept Together?
With their friendly and approachable nature, they are more than happy to live alongside one another.
Therefore, when keeping mystery snails you can add as many as to the tank as you like… as long as the tank size is large enough for the amount you have!!
These snails can be found in your local aquarium or pet store, but they can also be found easily online with a quick google search. Some online dealers include LiveAquaria.com and eBay, so they are readily available.
However, we don’t know how companies from places like eBay will transport your snail. Indeed, their shells are so sensitive, the most reliable place to purchase them is from your nearest pet store.
Generally, they sell for between $2 and $3 each.
Can You Breed Mystery Snails?
You most certainly can try for your own snail babies, but unlike many snails they aren’t hermaphroditic. So breeding mystery snails requires a male and female to do the trick.
To check your snail’s gender, lift them up and wait for it to exit its shell. Look at the upper part of the left side, and if you see a long protrusion, it’s a male.
If you’re having trouble deciding if your mystery snail is male or female, this video might help you out.
When the female becomes pregnant, she will lay her pale pink mystery snail eggs above the water line. Therefore, again, it’s important to provide a perch for them above the water line in the aquarium, as they should not be left underwater.
The eggs should hatch within about two to four weeks but, if infertile, they will turn a yellow color and dry out.
Nevertheless, if they do hatch, the babies will need a lot of algae to survive, so make sure the tank isn’t too clean. Generally, they need minimal aid to breed, so leave them to it and they should do their thing naturally.
Interesting Facts and Trivia
Before purchasing your friendly, neighborhood snail, there are a few extra facts about it that you might like to know:
- They are called apple snails as they can sometimes grow to the size of an apple.
- Like all snails, this creature has no arteries or veins—their heart pumps blood throughout the entire body.
- They have gills and lungs, so they can live both on land and in water.
Overall, one of the top tips you need to remember for mystery snail care is that their shell is extremely important to look after. Therefore, keeping an eye on water quality and the water parameters, as detailed above, is paramount. Calcium supplements can often be helpful to maintain their shell strength.
Whatever level of fishkeeper you are, a mystery snail will be a good choice. Indeed, minimal tank cleaning is needed for them, as they will eat the algae throughout the day and night.
Generally, as long as their tank mates won’t eat them, they are a friend for any other creature joining them. As long as you provide them a little perch to sit on above the water to breathe, they’ll thrive.
These friendly and colorful creatures are super easy to maintain and will make a great addition to your tank.
