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.
Moonlight Gourami and X-Ray Tetra receive a recommended verdict from the current structured assessment. Moonlight Gourami is recorded as peaceful with an aggression level of 2/10; X-Ray 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.
Moonlight Gourami has a recorded temperature range of 77–86°F and pH range of 6–7.5. X-Ray Tetra is recorded at 72–82°F and pH 6–8. Their shared planning window is 77–82°F for temperature and 6–7.5 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 15 gallons. Moonlight Gourami is the larger adult by the recorded maximum, reaching 6 inches, compared with 1.8 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. X-Ray Tetra is moderate, uses the mid zone, and has a moderate flow preference. Moonlight Gourami does not have a recorded minimum school larger than one, while x-ray tetra should be planned as a group of at least 6. 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 X-Ray Tetra is a omnivore with easy 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.
