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.
Kribensis and Red Eye Tetra receive a conditional verdict from the current structured assessment. Kribensis is recorded as semi-aggressive with an aggression level of 4/10; Red Eye Tetra 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.
Kribensis has a recorded temperature range of 75–82°F and pH range of 5.6–7.5. Red Eye Tetra is recorded at 72–82°F and pH 6–8. Their shared planning window is 75–82°F for temperature and 6–7.5 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Kribensis sets the larger listed base aquarium requirement at 20 gallons; the other listed minimum is 20 gallons. Kribensis is the larger adult by the recorded maximum, reaching 4 inches, compared with 2.8 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Kribensis is a moderate species associated with the cave zone and moderate flow. Red Eye Tetra is active, uses the mid zone, and has a moderate flow preference. Kribensis should be planned as a group of at least 2, while red eye 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.
Kribensis is recorded as a omnivore with easy care, while Red Eye Tetra is a omnivore with easy 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.
