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.
Neon Tetra and Rosy Barb receive a recommended verdict from the current structured assessment. Neon Tetra is recorded as peaceful with an aggression level of 1/10; Rosy Barb 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.
Neon Tetra has a recorded temperature range of 70–81°F and pH range of 6–7.5. Rosy Barb is recorded at 64–79°F and pH 6–8. Their shared planning window is 70–79°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.
Rosy Barb sets the larger listed base aquarium requirement at 30 gallons; the other listed minimum is 10 gallons. Rosy Barb is the larger adult by the recorded maximum, reaching 5 inches, compared with 1.5 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Neon Tetra is a moderate species associated with the mid zone and moderate flow. Rosy Barb is active, uses the mid zone, and has a moderate flow preference. Neon Tetra should be planned as a group of at least 6, while rosy barb should be planned as a group of at least 6. The aquarium must support both social structures without forcing either species into insufficient space.
Neon Tetra is recorded as a omnivore with easy care, while Rosy Barb is a omnivore with easy care. Their listed preferred tank styles are blackwater 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.
