No automatic safety blocker was found.
Ember Tetra and Sailfin Molly receive a conditional verdict from the current structured assessment. Ember Tetra is recorded as peaceful with an aggression level of 1/10; Sailfin Molly 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.
Ember Tetra has a recorded temperature range of 72–82°F and pH range of 5.5–7.2. Sailfin Molly is recorded at 72–82°F and pH 7–8.5. Their shared planning window is 72–82°F for temperature and 7–7.2 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Sailfin Molly sets the larger listed base aquarium requirement at 30 gallons; the other listed minimum is 10 gallons. Sailfin Molly is the larger adult by the recorded maximum, reaching 5 inches, compared with 1 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Ember Tetra is a moderate species associated with the mid zone and moderate flow. Sailfin Molly is active, uses the top zone, and has a moderate flow preference. Ember Tetra should be planned as a group of at least 8, while sailfin molly should be planned as a group of at least 3. The aquarium must support both social structures without forcing either species into insufficient space.
Ember Tetra is recorded as a omnivore with easy care, while Sailfin Molly is a omnivore with intermediate 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.
Use these pair-specific boundaries before treating the verdict as an acceptable stocking plan.
