Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Betta and Crystal Red Shrimp receive a not recommended verdict from the current structured assessment. Betta is recorded as semi-aggressive with an aggression level of 6/10; Crystal Red Shrimp 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.
Betta has a recorded temperature range of 76–82°F and pH range of 6.5–7.5. Crystal Red Shrimp is recorded at 68–76°F and pH 6–7.2. Their shared planning window is 76–76°F for temperature and 6.5–7.2 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Betta sets the larger listed base aquarium requirement at 5 gallons; the other listed minimum is 5 gallons. Betta is the larger adult by the recorded maximum, reaching 3 inches, compared with 1.2 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Betta is a calm species associated with the top zone and low flow. Crystal Red Shrimp is moderate, uses the bottom zone, and has a moderate flow preference. Betta does not have a recorded minimum school larger than one, while crystal red shrimp should be planned as a group of at least 10. The aquarium must support both social structures without forcing either species into insufficient space.
Betta is recorded as a carnivore with easy care, while Crystal Red Shrimp is a omnivore with advanced 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.
