Clown Loach and Sailfin Molly receive a conditional verdict from the current structured assessment. Clown Loach is recorded as peaceful with an aggression level of 2/10; 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.
Clown Loach has a recorded temperature range of 75–86°F and pH range of 6–7.5. Sailfin Molly is recorded at 72–82°F and pH 7–8.5. Their shared planning window is 75–82°F for temperature and 7–7.5 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Clown Loach sets the larger listed base aquarium requirement at 100 gallons; the other listed minimum is 30 gallons. Clown Loach is the larger adult by the recorded maximum, reaching 12 inches, compared with 5 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Clown Loach is a active species associated with the bottom zone and moderate flow. Sailfin Molly is active, uses the top zone, and has a moderate flow preference. Clown Loach should be planned as a group of at least 6, 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.
Clown Loach is recorded as a omnivore with advanced 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.
