Why This Pair Received Its Verdict

Mystery Snail and Neon Tetra receive a conditional verdict from the current structured assessment. Mystery Snail is recorded as peaceful with an aggression level of 1/10; Neon Tetra 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.

  • Temperature ranges overlap well.
  • pH requirements overlap well.
  • Species have similar temperament.
  • One species should be maintained in a proper school or group.

Water Parameter Overlap

Mystery Snail has a recorded temperature range of 68–82°F and pH range of 7–8.4. Neon Tetra is recorded at 70–81°F and pH 6–7.5. Their shared planning window is 70–81°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.

Aquarium Space and Adult Size

Neon Tetra sets the larger listed base aquarium requirement at 10 gallons; the other listed minimum is 5 gallons. Mystery Snail is the larger adult by the recorded maximum, reaching 2 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.

Behavior and Social Requirements

Mystery Snail is a moderate species associated with the bottom zone and moderate flow. Neon Tetra is moderate, uses the mid zone, and has a moderate flow preference. Mystery Snail does not have a recorded minimum school larger than one, while neon tetra should be planned as a group of at least 6. The aquarium must support both social structures without forcing either species into insufficient space.

Husbandry Fit

Mystery Snail is recorded as a omnivore with easy care, while Neon Tetra 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.

What Would Change the Decision?

Use these pair-specific boundaries before treating the verdict as an acceptable stocking plan.

  • Do not proceed unless one stable temperature and pH range can be maintained for both Mystery Snail and Neon Tetra; acclimation does not correct an incompatible long-term range.
  • Treat size, predation, and fin-damage warnings as stop conditions. Extra plants cannot reliably make an unsafe predator-to-prey or fin-target pairing safe.
  • Use broken sight lines and multiple retreats, then separate the pair if either species shows persistent chasing, hiding, clamped fins, or loss of feeding access.
  • Recalculate space using the full adult group sizes—not one specimen of each species—and reject the plan if either species must be understocked socially to fit.
  • Prepare a cycled backup or separation option before introduction; individual behavior can be less predictable than species-level records.

Aquarium Planning Checklist

  • Keep temperature within 70–81°F.
  • Keep pH within 7–7.5.
  • Use at least the larger 10-gallon base requirement before accounting for the complete stocking plan.
  • Mystery Snail does not have a recorded minimum school larger than one; neon tetra should be planned as a group of at least 6.
  • Provide a separation plan and monitor feeding, stress, chasing, damaged fins, and access to preferred habitat zones.

Final Recommendation

Only plan this pair if every listed condition can be met, and have a separation plan if stress or aggression appears.
