Why This Pair Received Its Verdict

White Cloud Mountain Minnow and Yoyo Loach receive a not recommended verdict from the current structured assessment. White Cloud Mountain Minnow is recorded as peaceful with an aggression level of 1/10; Yoyo Loach is recorded as semi-aggressive with an aggression level of 4/10. The recommendation is based on the combined water, space, behavior, grouping, and predation checks below rather than on species names alone.

  • Temperature requirements conflict.
  • pH requirements overlap well.
  • One species may be semi-aggressive and require planning.
  • Both species have compatible schooling or group behavior.

Water Parameter Overlap

White Cloud Mountain Minnow has a recorded temperature range of 64–72°F and pH range of 6–8. Yoyo Loach is recorded at 75–86°F and pH 6.5–7.5. Their shared planning window is no complete overlap in the recorded ranges for temperature and 6.5–7.5 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.

Aquarium Space and Adult Size

Yoyo Loach sets the larger listed base aquarium requirement at 40 gallons; the other listed minimum is 10 gallons. Yoyo Loach is the larger adult by the recorded maximum, reaching 6.1 inches, compared with 1.5 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.

Behavior and Social Requirements

White Cloud Mountain Minnow is a active species associated with the top zone and moderate flow. Yoyo Loach is boisterous, uses the bottom zone, and has a moderate flow preference. White Cloud Mountain Minnow should be planned as a group of at least 6, while yoyo loach should be planned as a group of at least 5. The aquarium must support both social structures without forcing either species into insufficient space.

Husbandry Fit

White Cloud Mountain Minnow is recorded as a omnivore with easy care, while Yoyo Loach is a omnivore with intermediate care. Their listed preferred tank styles are planted and rockwork. Feeding access, cover, open swimming room, filtration, and observation should be planned around the more demanding requirement rather than averaged between the two species.

What Would Change the Decision?

Use these pair-specific boundaries before treating the verdict as an acceptable stocking plan.

  • Do not proceed unless one stable temperature and pH range can be maintained for both White Cloud Mountain Minnow and Yoyo Loach; acclimation does not correct an incompatible long-term range.
  • Treat size, predation, and fin-damage warnings as stop conditions. Extra plants cannot reliably make an unsafe predator-to-prey or fin-target pairing safe.
  • Use broken sight lines and multiple retreats, then separate the pair if either species shows persistent chasing, hiding, clamped fins, or loss of feeding access.
  • Recalculate space using the full adult group sizes—not one specimen of each species—and reject the plan if either species must be understocked socially to fit.
  • A different tank mate is the preferred decision for this pair. Attempting the combination transfers the identified risk to the animals rather than resolving it.

Aquarium Planning Checklist

  • Keep temperature within no complete overlap in the recorded ranges.
  • Keep pH within 6.5–7.5.
  • Use at least the larger 40-gallon base requirement before accounting for the complete stocking plan.
  • White Cloud Mountain Minnow should be planned as a group of at least 6; yoyo loach should be planned as a group of at least 5.
  • Choose separate aquariums or a different tank mate instead of attempting to manage a known blocking risk.

Final Recommendation

Do not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
