Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Kuhli Loach and Pea Puffer receive a not recommended verdict from the current structured assessment. Kuhli Loach is recorded as peaceful with an aggression level of 1/10; 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.
Kuhli Loach has a recorded temperature range of 75–86°F and pH range of 5.5–7. Pea Puffer is recorded at 74–82°F and pH 6.8–8. Their shared planning window is 75–82°F for temperature and 6.8–7 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Kuhli Loach sets the larger listed base aquarium requirement at 20 gallons; the other listed minimum is 10 gallons. Kuhli Loach is the larger adult by the recorded maximum, reaching 4 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.
Kuhli Loach is a moderate species associated with the bottom zone and moderate flow. Pea Puffer is moderate, uses the mid zone, and has a moderate flow preference. Kuhli Loach should be planned as a group of at least 5, 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.
Kuhli Loach is recorded as a omnivore with intermediate care, while Pea Puffer is a carnivore with advanced care. Their listed preferred tank styles are blackwater 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.
