Planning verdict
compatibleThis pair is a reasonable starting point when both species receive their required tank size, group size, water conditions, and routine care.
No automatic safety blocker was found.
Corydoras Catfish and Green Severum receive a recommended verdict from the current structured assessment. Corydoras Catfish is recorded as peaceful with an aggression level of 1/10; Green Severum 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.
Corydoras Catfish has a recorded temperature range of 72–79°F and pH range of 6–7.5. Green Severum is recorded at 75–84°F and pH 6–7.5. Their shared planning window is 75–79°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.
Green Severum sets the larger listed base aquarium requirement at 75 gallons; the other listed minimum is 20 gallons. Green Severum is the larger adult by the recorded maximum, reaching 10 inches, compared with 3 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Corydoras Catfish is a moderate species associated with the bottom zone and moderate flow. Green Severum is moderate, uses the mid zone, and has a moderate flow preference. Corydoras Catfish should be planned as a group of at least 6, while green severum does not have a recorded minimum school larger than one. The aquarium must support both social structures without forcing either species into insufficient space.
Corydoras Catfish is recorded as a omnivore with easy care, while Green Severum is a omnivore with intermediate care. Their listed preferred tank styles are planted and community. Feeding access, cover, open swimming room, filtration, and observation should be planned around the more demanding requirement rather than averaged between the two species.
