Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Buenos Aires Tetra and Pea Puffer receive a not recommended verdict from the current structured assessment. Buenos Aires Tetra is recorded as semi-aggressive with an aggression level of 3/10; Pea Puffer 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.
Buenos Aires Tetra has a recorded temperature range of 64–82°F and pH range of 6–8. Pea Puffer is recorded at 74–82°F and pH 6.8–8. Their shared planning window is 74–82°F for temperature and 6.8–8 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Buenos Aires Tetra sets the larger listed base aquarium requirement at 30 gallons; the other listed minimum is 10 gallons. Buenos Aires Tetra is the larger adult by the recorded maximum, reaching 2.8 inches, compared with 1.4 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Buenos Aires Tetra is a boisterous species associated with the mid zone and moderate flow. Pea Puffer is moderate, uses the mid zone, and has a moderate flow preference. Buenos Aires Tetra should be planned as a group of at least 6, while pea puffer should be planned as a group of at least 6. The aquarium must support both social structures without forcing either species into insufficient space.
Buenos Aires Tetra is recorded as a omnivore with easy care, while Pea Puffer is a carnivore with advanced care. Their listed preferred tank styles are community and species_only. 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.
