Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Paradise Fish and Rope Fish receive a not recommended verdict from the current structured assessment. Paradise Fish is recorded as semi-aggressive with an aggression level of 6/10; Rope Fish is recorded as semi-aggressive with an aggression level of 4/10. The recommendation is based on the combined water, space, behavior, grouping, and predation checks below rather than on species names alone.
Paradise Fish has a recorded temperature range of 64–78°F and pH range of 6–8. Rope Fish is recorded at 72–82°F and pH 6–7.5. Their shared planning window is 72–78°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 4 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Paradise Fish is a moderate species associated with the top zone and low flow. Rope Fish is moderate, uses the bottom zone, and has a moderate flow preference. Paradise Fish does not have a recorded minimum school larger than one, while rope fish does not have a recorded minimum school larger than one. The aquarium must support both social structures without forcing either species into insufficient space.
Paradise Fish is recorded as a carnivore with intermediate care, while Rope Fish is a carnivore with advanced care. Their listed preferred tank styles are planted and predator. 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.
