- Hardness both tolerate: 5–15 dGH
- Recommended combined tank: 16 gallons or larger
Risks and things to watch
Temperature conflict
The comfortable ranges barely meet. Running one species at the edge of its range for months is a slow-burn health problem, not an instant one — which is why it often goes unnoticed.
Both occupy the top zone
Competition for space and food is higher when two species share the same layer. Increase footprint rather than height.
Group requirements
Compatibility is not only about the two species getting along — each still needs its own social setup met inside the same tank.
- Dwarf Gourami — no group requirement; single specimens are fine.
- White Cloud Mountain Minnow — minimum group of 6. Budget tank space for the whole shoal, not one fish.
Frequently asked questions
Can dwarf gourami and white cloud mountain minnow live together?
Possible, with conditions. Dwarf Gourami and White Cloud Mountain Minnow 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 16 gallons minimum.
What size tank do dwarf gourami and white cloud mountain minnow need together?
Plan for at least 16 gallons. Dwarf Gourami alone needs 10 gallons and White Cloud Mountain Minnow needs 10, but combined stocking needs headroom for filtration and swimming space, not just volume.
What temperature suits both species?
Both are comfortable between 72 and 72°F. Set the heater to the middle of that window and keep it stable.
What pH works for both?
Aim for pH 6–7.5, which sits inside both species' comfortable range.
Will dwarf gourami eat white cloud mountain minnow?
Unlikely. At 3.5″ versus 1.5″ 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.
