Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Rope Fish and Sterbai Cory receive a not recommended verdict from the current structured assessment. Rope Fish is recorded as semi-aggressive with an aggression level of 4/10; Sterbai Cory is recorded as peaceful with an aggression level of 1/10. The recommendation is based on the combined water, space, behavior, grouping, and predation checks below rather than on species names alone.
Rope Fish has a recorded temperature range of 72–82°F and pH range of 6–7.5. Sterbai Cory is recorded at 75–82°F and pH 6–7.6. Their shared planning window is 75–82°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.
Rope Fish sets the larger listed base aquarium requirement at 75 gallons; the other listed minimum is 20 gallons. Rope Fish is the larger adult by the recorded maximum, reaching 15 inches, compared with 2.6 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Rope Fish is a moderate species associated with the bottom zone and moderate flow. Sterbai Cory is moderate, uses the bottom zone, and has a moderate flow preference. Rope Fish does not have a recorded minimum school larger than one, while sterbai cory should be planned as a group of at least 6. The aquarium must support both social structures without forcing either species into insufficient space.
Rope Fish is recorded as a carnivore with advanced care, while Sterbai Cory is a omnivore with easy care. Their listed preferred tank styles are predator 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.
