Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Pea Puffer and Zebra Loach receive a not recommended verdict from the current structured assessment. Pea Puffer is recorded as semi-aggressive with an aggression level of 5/10; 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.
Pea Puffer has a recorded temperature range of 74–82°F and pH range of 6.8–8. Zebra Loach is recorded at 73–79°F and pH 6–7.5. Their shared planning window is 74–79°F for temperature and 6.8–7.5 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 1.4 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Pea Puffer is a moderate species associated with the mid zone and moderate flow. Zebra Loach is active, uses the bottom zone, and has a moderate flow preference. Pea Puffer 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.
Pea Puffer is recorded as a carnivore with advanced care, while Zebra Loach is a omnivore with easy care. Their listed preferred tank styles are species_only 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.
