Blocking risks

  • Two non-peaceful species require cautious stocking, sufficient space, and close behavior monitoring.
  • Both species defend territory aggressively and are likely to stress or injure each other.
  • Territorial footprint and swimming zone overlap require extra space and cover.
  • Breeding aggression can turn an otherwise workable pairing into a caution setup.

Conditions and cautions

  • pH ranges have limited overlap.
  • Both species are territorial with high aggression, creating a serious space conflict.
  • Tank size requirements differ moderately.

Supporting factors

  • Temperature ranges overlap well.
  • Both species have compatible schooling or group behavior.
  • No predation risk detected.

Why This Pair Received Its Verdict

Convict Cichlid and Electric Yellow Cichlid receive a not recommended verdict from the current structured assessment. Convict Cichlid is recorded as aggressive with an aggression level of 8/10; Electric Yellow Cichlid is recorded as semi-aggressive with an aggression level of 5/10. 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 ranges have limited overlap.
  • Both species are territorial with high aggression, creating a serious space conflict.
  • Both species have compatible schooling or group behavior.

Water Parameter Overlap

Convict Cichlid has a recorded temperature range of 75–82°F and pH range of 6.6–7.8. Electric Yellow Cichlid is recorded at 73–79°F and pH 7.8–8.9. Their shared planning window is 75–79°F for temperature and 7.8–7.8 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.

Aquarium Space and Adult Size

Electric Yellow Cichlid sets the larger listed base aquarium requirement at 55 gallons; the other listed minimum is 30 gallons. Convict Cichlid is the larger adult by the recorded maximum, reaching 6 inches, compared with 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

Convict Cichlid is a moderate species associated with the cave zone and moderate flow. Electric Yellow Cichlid is moderate, uses the mid zone, and has a moderate flow preference. Convict Cichlid should be planned as a group of at least 2, while electric yellow cichlid should be planned as a group of at least 4. The aquarium must support both social structures without forcing either species into insufficient space.

Husbandry Fit

Convict Cichlid is recorded as a omnivore with intermediate care, while Electric Yellow Cichlid is a omnivore with intermediate care. Their listed preferred tank styles are rockwork and rockwork. 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 Convict Cichlid and Electric Yellow Cichlid; 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.
  • A different tank mate is the preferred decision for this pair. Attempting the combination transfers the identified risk to the animals rather than resolving it.

Aquarium Planning Checklist

  • Keep temperature within 75–79°F.
  • Keep pH within 7.8–7.8.
  • Use at least the larger 55-gallon base requirement before accounting for the complete stocking plan.
  • Convict Cichlid should be planned as a group of at least 2; electric yellow cichlid should be planned as a group of at least 4.
  • Choose separate aquariums or a different tank mate instead of attempting to manage a known blocking risk.

Final Recommendation

Do not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
