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.
Glowlight Tetra and Pearl Gourami receive a recommended verdict from the current structured assessment. Glowlight Tetra is recorded as peaceful with an aggression level of 1/10; Pearl Gourami 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.
Glowlight Tetra has a recorded temperature range of 74–82°F and pH range of 6–7.5. Pearl Gourami is recorded at 75–82°F and pH 5.5–7.5. Their shared planning window is 75–82°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.
Pearl Gourami sets the larger listed base aquarium requirement at 30 gallons; the other listed minimum is 15 gallons. Pearl Gourami is the larger adult by the recorded maximum, reaching 4.7 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.
Glowlight Tetra is a moderate species associated with the mid zone and moderate flow. Pearl Gourami is calm, uses the top zone, and has a low flow preference. Glowlight Tetra should be planned as a group of at least 6, while pearl gourami does not have a recorded minimum school larger than one. The aquarium must support both social structures without forcing either species into insufficient space.
Glowlight Tetra is recorded as a omnivore with easy care, while Pearl Gourami is a omnivore with easy 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.
