Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Crystal Red Shrimp and German Blue Ram receive a not recommended verdict from the current structured assessment. Crystal Red Shrimp is recorded as peaceful with an aggression level of 1/10; German Blue Ram is recorded as peaceful with an aggression level of 3/10. The recommendation is based on the combined water, space, behavior, grouping, and predation checks below rather than on species names alone.
Crystal Red Shrimp has a recorded temperature range of 68–76°F and pH range of 6–7.2. German Blue Ram is recorded at 78–86°F and pH 5.2–6.8. Their shared planning window is no complete overlap in the recorded ranges for temperature and 6–6.8 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
German Blue Ram sets the larger listed base aquarium requirement at 20 gallons; the other listed minimum is 5 gallons. German Blue Ram 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.
Crystal Red Shrimp is a moderate species associated with the bottom zone and moderate flow. German Blue Ram is moderate, uses the bottom zone, and has a moderate flow preference. Crystal Red Shrimp should be planned as a group of at least 10, while german blue ram should be planned as a group of at least 2. The aquarium must support both social structures without forcing either species into insufficient space.
Crystal Red Shrimp is recorded as a omnivore with advanced care, while German Blue Ram is a omnivore with advanced 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.
Use these pair-specific boundaries before treating the verdict as an acceptable stocking plan.
