Planning verdict
cautionOnly plan this pair if every listed condition can be met, and have a separation plan if stress or aggression appears.
No automatic safety blocker was found.
Black Neon Tetra and Reticulated Hillstream Loach receive a conditional verdict from the current structured assessment. Black Neon Tetra is recorded as peaceful with an aggression level of 1/10; Reticulated Hillstream Loach 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.
Black Neon Tetra has a recorded temperature range of 72–80°F and pH range of 5.5–7.5. Reticulated Hillstream Loach is recorded at 68–76°F and pH 6.5–7.5. Their shared planning window is 72–76°F for temperature and 6.5–7.5 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Reticulated Hillstream Loach sets the larger listed base aquarium requirement at 20 gallons; the other listed minimum is 15 gallons. Reticulated Hillstream Loach is the larger adult by the recorded maximum, reaching 3 inches, compared with 1.6 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Black Neon Tetra is a moderate species associated with the mid zone and moderate flow. Reticulated Hillstream Loach is moderate, uses the bottom zone, and has a high flow preference. Black Neon Tetra should be planned as a group of at least 6, while reticulated hillstream 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.
Black Neon Tetra is recorded as a omnivore with easy care, while Reticulated Hillstream Loach is a herbivore with advanced care. Their listed preferred tank styles are planted and stream. 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.
