No automatic safety blocker was found.
Pygmy Cory and Three Spot Gourami receive a conditional verdict from the current structured assessment. Pygmy Cory is recorded as peaceful with an aggression level of 1/10; Three Spot Gourami is recorded as semi-aggressive with an aggression level of 5/10. The recommendation is based on the combined water, space, behavior, grouping, and predation checks below rather than on species names alone.
Pygmy Cory has a recorded temperature range of 72–79°F and pH range of 6–7.5. Three Spot Gourami is recorded at 74–82°F and pH 6–8. Their shared planning window is 74–79°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.
Three Spot Gourami sets the larger listed base aquarium requirement at 30 gallons; the other listed minimum is 10 gallons. Three Spot Gourami is the larger adult by the recorded maximum, reaching 6 inches, compared with 1.2 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Pygmy Cory is a moderate species associated with the bottom zone and moderate flow. Three Spot Gourami is moderate, uses the top zone, and has a low flow preference. Pygmy Cory should be planned as a group of at least 8, while three spot gourami does not have a recorded minimum school larger than one. The aquarium must support both social structures without forcing either species into insufficient space.
Pygmy Cory is recorded as a omnivore with intermediate care, while Three Spot Gourami 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.
