No automatic safety blocker was found.
Otocinclus Catfish and Zebra Loach receive a conditional verdict from the current structured assessment. Otocinclus Catfish is recorded as peaceful with an aggression level of 1/10; Zebra Loach is recorded as peaceful with an aggression level of 2/10. The recommendation is based on the combined water, space, behavior, grouping, and predation checks below rather than on species names alone.
Otocinclus Catfish has a recorded temperature range of 72–79°F and pH range of 6–7.5. Zebra Loach is recorded at 73–79°F and pH 6–7.5. Their shared planning window is 73–79°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.
Zebra Loach sets the larger listed base aquarium requirement at 30 gallons; the other listed minimum is 10 gallons. Zebra Loach is the larger adult by the recorded maximum, reaching 4 inches, compared with 2 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. Zebra Loach is active, uses the bottom zone, and has a moderate flow preference. Otocinclus Catfish should be planned as a group of at least 6, while zebra 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.
Otocinclus Catfish is recorded as a herbivore with intermediate care, while Zebra Loach 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.
Use these pair-specific boundaries before treating the verdict as an acceptable stocking plan.
