Can Betta Fish Live With White Cloud Mountain Minnow?
No, bettas need warm 76-82F water while White Cloud Mountain Minnows need cool 60-72F water, and these temperature ranges do not overlap.
Why
- Betta fish need 76-82 degrees Fahrenheit, which is 4-10 degrees warmer than the 60-72 degrees White Cloud Mountain Minnows require.
- White Cloud Mountain Minnows are coldwater fish from mountain streams that thrive without a heater, and sustained temperatures above 75F stress them.
- Bettas are tropical fish that become lethargic and prone to disease if water drops below 76F, so there is no workable middle ground.
- Temperature mismatch is a structural incompatibility that cannot be resolved by tank size or tankmate selection.
What could go wrong
If the tank runs warm for the betta, the minnows overheat and experience stress, loss of color, and shortened lifespan. If cool for the minnows, the betta chills and becomes disease-prone.

Keep ammonia, nitrite, and nitrate in check. Two-species tanks have more bioload and less margin for error than single-species setups.
Better pairings to consider
Bettas do well with nerite snails, mystery snails, and bronze corydoras in heated 10-gallon tanks. White Cloud Mountain Minnows do well with zebra danios, cherry barbs, and celestial pearl danios in unheated 20-gallon tanks.
