Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Chili Rasbora and Discus receive a not recommended verdict from the current structured assessment. Chili Rasbora is recorded as peaceful with an aggression level of 1/10; Discus 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.
Chili Rasbora has a recorded temperature range of 73–80°F and pH range of 4.5–7. Discus is recorded at 82–86°F and pH 4.5–6.5. Their shared planning window is no complete overlap in the recorded ranges for temperature and 4.5–6.5 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Discus sets the larger listed base aquarium requirement at 75 gallons; the other listed minimum is 5 gallons. Discus is the larger adult by the recorded maximum, reaching 8 inches, compared with 0.8 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Chili Rasbora is a moderate species associated with the mid zone and moderate flow. Discus is calm, uses the mid zone, and has a low flow preference. Chili Rasbora should be planned as a group of at least 8, while discus should be planned as a group of at least 6. The aquarium must support both social structures without forcing either species into insufficient space.
Chili Rasbora is recorded as a carnivore with intermediate care, while Discus is a omnivore with advanced care. Their listed preferred tank styles are blackwater and blackwater. 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.
