- Temperature: 68-84°F (20-29°C)
- pH: 7.0 – 8.0. An acidic pH (below 7.0) will slowly dissolve their shells.
- Hardness: They need moderately hard water with sufficient calcium. A GH of 8-18 dGH is ideal. You can add crushed coral or a cuttlebone to your filter to help maintain hardness and provide calcium.
- A Secure Lid: This is non-negotiable. Ensure there are no snail-sized gaps for them to escape through.
What to Feed Your Mystery Snails
A common mistake is assuming snails can survive solely on algae and leftovers. While they are great at cleaning, a healthy snail needs a dedicated diet.
Supplement their grazing with high-quality sinking foods like algae wafers, shrimp pellets, or crab cuisine. They also love blanched vegetables like zucchini, spinach, cucumber, and carrots. This provides essential nutrients they might not get otherwise.
Acclimation: The Crucial First Step
Snails are sensitive to sudden changes in water parameters. Never just drop a new snail into your tank! The best method is drip acclimation.
- Place the snail and its bag water into a small container.
- Using a piece of airline tubing, start a slow siphon from your main tank into the container.
- Tie a knot in the tubing or use a valve to restrict the flow to a few drops per second.
- Let it drip for about an hour, allowing the water volume in the container to double.
- Once acclimated, gently net the snail and place it in your aquarium. Discard the container water.
Tank Mates: Choosing Friends, Not Foes
Choosing the right neighbors is key. Good tank mates include most peaceful community fish.
- Great Companions: Bettas (most), Tetras, Guppies, Corydoras, Otocinclus, and freshwater shrimp.
- Avoid These: Loaches (like Clown or Yoyo Loaches), Pufferfish, large and aggressive Cichlids, and Goldfish are all known snail-eaters.

Common Problems with Mystery Snails and How to Solve Them
Even with the best care, you might run into a few issues. Don’t worry! Here’s a quick guide to troubleshooting some of the most common problems with are mystery snails good for aquarium keepers.
My Snail Isn’t Moving! Is it Dead?
Snails can remain inactive for long periods, sometimes even staying closed up for a day or two. This is often normal resting behavior. To check if it’s alive, gently pick it up. If the trapdoor (operculum) is shut tight, it’s fine. A dead snail will hang limply out of its shell and have a distinct, terrible odor.
Shell Deterioration: Cracks and Pitting
If you see the shell looking thin, pitted, or cracked, it’s almost always a sign of low calcium or a low pH. Test your water parameters. Add a source of calcium like crushed coral, a cuttlebone, or feed them calcium-rich vegetables to help them repair their shells.
The Great Escape: Preventing Runaways
As mentioned, a tight-fitting lid is the only surefire solution. They often try to escape to lay eggs, so keeping the water level an inch or two below the rim can also give them a place to lay clutches without leaving the tank entirely.
Floating Snails: What Does It Mean?
Sometimes a snail will trap air in its shell and float at the surface. This is usually harmless and they will typically expel the air and sink on their own within a day. If it persists or the snail seems unwell, it could be a sign of poor water quality, so be sure to test your parameters.
Frequently Asked Questions About Mystery Snails
How many mystery snails should I get for my aquarium?
A good rule of thumb is one mystery snail per 5 gallons of water. For a 20-gallon tank, 3-4 snails would be a good number to start with. This prevents them from overwhelming your filtration system with their waste.
Do mystery snails eat live plants?
Generally, no. A healthy, well-fed Pomacea bridgesii will ignore your live plants. They much prefer softer foods like algae, biofilm, and decaying plant matter. If you see them munching on a leaf, it’s likely that the leaf was already dying.
Will mystery snails overpopulate my tank?
They can if you let them. Unlike pest snails that reproduce underwater, mystery snails lay distinct, bright pink egg clutches above the waterline. These clutches are very easy to spot and remove if you don’t want babies, giving you full control over their population.
Why is my mystery snail’s trapdoor (operculum) closed?
A closed trapdoor can mean many things. The snail might be sleeping, stressed by a tank mate, or protecting itself from poor water conditions. It’s their way of sealing themselves off from the outside world. Check your water parameters and observe your other fish to see if anyone is bothering the snail.

They are more than just cleaners; they are engaging pets that bring color and activity to your underwater world. By understanding their simple needs—stable water, a calcium-rich diet, and a secure lid—you can unlock all the amazing benefits they have to offer.
