Otocinclus Catfish has a recorded temperature range of 72–79°F and pH range of 6–7.5. White Cloud Mountain Minnow is recorded at 64–72°F and pH 6–8. Their shared planning window is 72–72°F for temperature and 6–7.5 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Otocinclus Catfish sets the larger listed base aquarium requirement at 10 gallons; the other listed minimum is 10 gallons. Otocinclus Catfish is the larger adult by the recorded maximum, reaching 2 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.
Otocinclus Catfish is a moderate species associated with the bottom zone and moderate flow. White Cloud Mountain Minnow is active, uses the top zone, and has a moderate flow preference. Otocinclus Catfish should be planned as a group of at least 6, while white cloud mountain minnow should be planned as a group of at least 6. The aquarium must support both social structures without forcing either species into insufficient space.
Otocinclus Catfish is recorded as a herbivore with intermediate care, while White Cloud Mountain Minnow is a omnivore with easy care. Their listed preferred tank styles are planted and planted. Feeding access, cover, open swimming room, filtration, and observation should be planned around the more demanding requirement rather than averaged between the two species.
