Brilliant Rummynose Tetra and Weather Loach receive a conditional verdict from the current structured assessment. Brilliant Rummynose Tetra is recorded as peaceful with an aggression level of 1/10; Weather Loach 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.
Brilliant Rummynose Tetra has a recorded temperature range of 75–82°F and pH range of 5.5–7. Weather Loach is recorded at 50–77°F and pH 6.5–8. Their shared planning window is 75–77°F for temperature and 6.5–7 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Weather Loach sets the larger listed base aquarium requirement at 55 gallons; the other listed minimum is 20 gallons. Weather Loach is the larger adult by the recorded maximum, reaching 12 inches, compared with 2 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Brilliant Rummynose Tetra is a moderate species associated with the mid zone and moderate flow. Weather Loach is active, uses the bottom zone, and has a low flow preference. Brilliant Rummynose Tetra should be planned as a group of at least 8, while weather 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.
Brilliant Rummynose Tetra is recorded as a omnivore with intermediate care, while Weather Loach is a omnivore with intermediate care. Their listed preferred tank styles are blackwater 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.
Use these pair-specific boundaries before treating the verdict as an acceptable stocking plan.
