Compatibility brief
Can Betta live with White Cloud Mountain Minnow?
Risky. This mix is commonly discouraged for typical setups.
Compatibility score
Profile confidence: medium
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
40L
Combined minimum footprint reference for these two species: about 40L (larger active fish often want more length).
Temperament gap (semi-aggressive vs peaceful) adds stress on top of the hard incompatibility — space and cover do not make this pairing safe.

Next steps
Concrete changes, not "research more" filler.
- •Provide plenty of hiding spots and visual breaks so White Cloud Mountain Minnow can escape if harassed.
- •White Cloud Mountain Minnow should be kept in a group of at least 6 for best health and behaviour.
- •These fish cannot be comfortably housed together. Their temperature needs are incompatible.

Individual fish vary in personality. Fishori uses conservative hobby rules. Observe any new introduction closely, feed thoughtfully, and keep a quarantine or backup plan. This is not veterinary advice.
Profile data confidence: high. Checked against several solid care sources that mostly agree.
