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.
No additional conditional requirements were identified.
Amano Shrimp and Least Killifish receive a recommended verdict from the current structured assessment. Amano Shrimp is recorded as peaceful with an aggression level of 1/10; Least Killifish 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. Least Killifish is recorded at 68–78°F and pH 6.5–8. Their shared planning window is 68–78°F for temperature and 6.5–7.5 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Amano Shrimp sets the larger listed base aquarium requirement at 10 gallons; the other listed minimum is 5 gallons. Amano Shrimp is the larger adult by the recorded maximum, reaching 1.5 inches, compared with 1.2 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. Least Killifish is moderate, uses the top zone, and has a moderate flow preference. Amano Shrimp should be planned as a group of at least 3, while least killifish should be planned as a group of at least 6. 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 Least Killifish is a omnivore with intermediate care. Their listed preferred tank styles are planted and planted. Feeding access, cover, open swimming room, filtration, and observation should be planned around the more demanding requirement rather than averaged between the two species.
