Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Bubble Eye Goldfish and Zebra Loach receive a not recommended verdict from the current structured assessment. Bubble Eye Goldfish 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.
Bubble Eye Goldfish has a recorded temperature range of 65–75°F and pH range of 7–8. Zebra Loach is recorded at 73–79°F and pH 6–7.5. Their shared planning window is 73–75°F for temperature and 7–7.5 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Bubble Eye Goldfish sets the larger listed base aquarium requirement at 30 gallons; the other listed minimum is 30 gallons. Bubble Eye Goldfish is the larger adult by the recorded maximum, reaching 6 inches, compared with 4 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Bubble Eye Goldfish is a calm species associated with the mid zone and low flow. Zebra Loach is active, uses the bottom zone, and has a moderate flow preference. Bubble Eye Goldfish does not have a recorded minimum school larger than one, 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.
Bubble Eye Goldfish is recorded as a omnivore with advanced care, while Zebra Loach is a omnivore with easy care. Their listed preferred tank styles are goldfish 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.
