Freshwater Fish
White Cloud Mountain Minnow.
A hardy, cool-water minnow with red fins and a subtle stripe — one of the toughest beginner fish, and happy without a heater in a temperate room. Peaceful and best in a lively school in a 10-gallon-plus tank.

Good tank mates
White clouds are peaceful and community-safe, with the twist that they like cooler water, so they do best with other cool-water or temperate-tolerant fish rather than warm tropicals. Good company is other small, peaceful, cool-friendly fish and small schoolers; real examples that work are zebra danios, other white clouds in a bigger group, and small peaceful rasboras. Avoid larger or aggressive fish, skip fin-nippers, and don't keep them with anything big enough to eat a one-and-a-half-inch minnow.

Zebra Danio
Hardy, active, and similarly sized schooling fish whose temperature range (18–24°C) overlaps cleanly with the White Cloud's 14–22°C preference. No predation, size, or aggression concerns. A well-established and widely recommended pairing.
- R
Rosy Barb
Explicitly listed as compatible on the Seriously Fish White Cloud Mountain Minnow species page. Temperature ranges align well (Rosy Barb tolerates 15–22°C, overlapping cleanly with the White Cloud's 14–22°C preference). Fin-nipping risk exists in small groups but is well-documented as manageable when kept in schools of six or more with adequate space.
- O
Odessa Barb
Directly named on the Seriously Fish White Cloud species page. Technically tolerates down to 16°C (confirmed via multiple care guides), providing a functional overlap with the White Cloud at 20–22°C. Best kept at the cool end of the Odessa Barb's range to avoid stressing the minnows.
- C
Celestial Pearl Danio
A nano-sized, peaceful schooling fish with no predation or aggression risk toward WCMMs. Its minimum tolerable temperature is confirmed at approximately 18–20°C, which overlaps with the White Cloud's upper range of 20–22°C. Both species share similar peaceful temperament and community-tank suitability.
