Shared water parameters
- Temperature both tolerate: 68–82°F
- pH both tolerate: 7–8.5
- Hardness both tolerate: 8–20 dGH
- Recommended combined tank: 8 gallons or larger
Risks and things to watch
No major conflicts
Parameters, size and temperament all line up. The usual rules still apply: cycle the tank, respect group sizes, and do not overstock.
Group requirements
Compatibility is not only about the two species getting along — each still needs its own social setup met inside the same tank.
- Nerite Snail — no group requirement; single specimens are fine.
- Mystery Snail — no group requirement; single specimens are fine.
Frequently asked questions
Can nerite snail and mystery snail live together?
Possible, with conditions. Nerite Snail and Mystery Snail can work, but this is a conditional yes rather than easy one. Read the risk section below before buying — the pairing usually fails for one specific reason, not because of general incompatibility. Plan on 8 gallons minimum.
What size tank do nerite snail and mystery snail need together?
Plan for at least 8 gallons. Nerite Snail alone needs 5 gallons and Mystery Snail needs 5, but combined stocking needs headroom for filtration and swimming space, not just volume.
What temperature suits both species?
Both are comfortable between 68 and 82°F. Set the heater to the middle of that window and keep it stable.
What pH works for both?
Aim for pH 7–8.5, which sits inside both species' comfortable range.
Will mystery snail eat nerite snail?
Unlikely. At 2.0″ versus 1.0″ the size gap is not large enough for predation, though fry and juveniles are never safe in a community tank.
How should the tank be arranged?
Use plants, wood and rock to break sight lines, keep open swimming space along the front, and add the more territorial species last so it cannot claim the whole tank before the other settles in.
