Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Moonlight Gourami and Reticulated Hillstream Loach receive a not recommended verdict from the current structured assessment. Moonlight Gourami is recorded as peaceful with an aggression level of 2/10; Reticulated Hillstream Loach 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.
Moonlight Gourami has a recorded temperature range of 77–86°F and pH range of 6–7.5. Reticulated Hillstream Loach is recorded at 68–76°F and pH 6.5–7.5. Their shared planning window is no complete overlap in the recorded ranges 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.
Moonlight Gourami sets the larger listed base aquarium requirement at 30 gallons; the other listed minimum is 20 gallons. Moonlight Gourami is the larger adult by the recorded maximum, reaching 6 inches, compared with 3 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Moonlight Gourami is a calm species associated with the top zone and low flow. Reticulated Hillstream Loach is moderate, uses the bottom zone, and has a high flow preference. Moonlight Gourami does not have a recorded minimum school larger than one, while reticulated hillstream loach should be planned as a group of at least 3. The aquarium must support both social structures without forcing either species into insufficient space.
Moonlight Gourami is recorded as a omnivore with easy care, while Reticulated Hillstream Loach is a herbivore with advanced care. Their listed preferred tank styles are planted and stream. 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.
