What fish can live with White Cloud Mountain Minnow?

Use the "Often compatible" lists as a shortlist, not a stocking plan. Always run the pair tool and check the footprint of your actual tank first. Verify behaviour for White Cloud Mountain Minnow against your own reading before you buy.

What tank mates should you avoid with White Cloud Mountain Minnow?

Avoid Discus, Betta, Oscar based on size, temperament, or predation risk on file.

What size tank do White Cloud Mountain Minnow need for a community?

40L is the planning floor for adult swimming space and bioload headroom. Long-term, a 49L+ tank lets adults use the full footprint without crowding the next species. Footprint, meaning length and front-to-back depth, matters as much as raw volume for active or territorial species.

White Cloud Mountain Minnow tank mates

Best tank mates (on file)

Merged from conservative safest and best with fields — de-duplicated by species.

Cherry Barb Pair check
The White Cloud Mountain Minnow profile lists Cherry Barb as both safe and a recommended pairing. Cherry Barb schools in groups of 6 or more, so plan room for the whole group rather than one fish. Water parameters barely overlap between the two, so check the temperature and pH ranges on both profiles before stocking.
Corydoras Catfish Pair check
The White Cloud Mountain Minnow profile lists Corydoras Catfish as both safe and a recommended pairing. Corydoras Catfish schools in groups of 6 or more, so plan room for the whole group rather than one fish. Corydoras Catfish swims in the bottom zone while White Cloud Mountain Minnow stays in the middle, so the two will not crowd the same water column.
Zebra Danio Pair check
The White Cloud Mountain Minnow profile lists Zebra Danio as both safe and a recommended pairing. Zebra Danio schools in groups of 6 or more, so plan room for the whole group rather than one fish.

Fish to avoid with White Cloud Mountain Minnow

From the unsafe list — predation, aggression, or space rules on this profile.

Discus See why (pair)
Discus needs at least 200L, far above the 40L minimum for White Cloud Mountain Minnow. The tank that houses one stresses the other.
Betta See why (pair)
Betta conflicts with White Cloud Mountain Minnow on temperament, predation, or footprint. The juvenile size in a shop tank is not the figure that matters here.
Oscar See why (pair)
Oscar reaches 35cm and is flagged predatory. White Cloud Mountain Minnow at 4cm is prey-sized for it. Oscar needs at least 300L, far above the 40L minimum for White Cloud Mountain Minnow. The tank that houses one stresses the other. Oscar is rated aggressive and White Cloud Mountain Minnow is rated peaceful. No community-style planning carries that gap.

Tank size and groups

Published minimum for White Cloud Mountain Minnow: 40L — group minimum 6 (schooling).
Compatibility changes when the tank is too short for turning, too little for a real school, or too warm for one species and not the other — that is why pair checks include tank context, not only temperament.
Nearest litre hub to this minimum: 40L hub.
