Planning verdict
cautionOnly plan this pair if every listed condition can be met, and have a separation plan if stress or aggression appears.
No automatic safety blocker was found.
Amano Shrimp and Cardinal Tetra receive a conditional verdict from the current structured assessment. Amano Shrimp is recorded as peaceful with an aggression level of 1/10; Cardinal Tetra 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.
Amano Shrimp has a recorded temperature range of 64–82°F and pH range of 6.5–7.5. Cardinal Tetra is recorded at 73–84°F and pH 5–7. Their shared planning window is 73–82°F for temperature and 6.5–7 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Cardinal Tetra sets the larger listed base aquarium requirement at 20 gallons; the other listed minimum is 10 gallons. Cardinal Tetra is the larger adult by the recorded maximum, reaching 2 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.
Amano Shrimp is a moderate species associated with the bottom zone and moderate flow. Cardinal Tetra is calm, uses the mid zone, and has a moderate flow preference. Amano Shrimp should be planned as a group of at least 3, while cardinal tetra should be planned as a group of at least 8. The aquarium must support both social structures without forcing either species into insufficient space.
Amano Shrimp is recorded as a omnivore with easy care, while Cardinal Tetra is a omnivore with intermediate care. Their listed preferred tank styles are planted 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.
