Dwarf Gourami and Mystery Snail are a good match. They share a workable temperature and pH window, neither is large enough to threaten the other, and temperaments are compatible. Give them at least 13 gallons once both group requirements are met.

Risks and things to watch

Mystery Snail may be eaten or harassed

Adult mystery snail are usually safe with small peaceful fish, but babies rarely survive. Dense moss and cholla wood give juveniles somewhere to hide. Never medicate the tank with copper.

Group requirements

Compatibility is not only about the two species getting along — each still needs its own social setup met inside the same tank.

Frequently asked questions

Can dwarf gourami and mystery snail live together?

Yes — compatible. Dwarf Gourami and Mystery Snail are a good match. They share a workable temperature and pH window, neither is large enough to threaten the other, and temperaments are compatible. Give them at least 13 gallons once both group requirements are met.

What size tank do dwarf gourami and mystery snail need together?

Plan for at least 13 gallons. Dwarf Gourami alone needs 10 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 72 and 82°F. Set the heater to the middle of that window and keep it stable.

What pH works for both?

Aim for pH 7–7.5, which sits inside both species' comfortable range.

Will dwarf gourami eat mystery snail?

Unlikely. At 3.5″ versus 2.0″ 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.
