Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Black Moor Goldfish and Crystal Red Shrimp receive a not recommended verdict from the current structured assessment. Black Moor Goldfish is recorded as peaceful with an aggression level of 1/10; 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.
Black Moor Goldfish has a recorded temperature range of 65–75°F and pH range of 7–8. Crystal Red Shrimp is recorded at 68–76°F and pH 6–7.2. Their shared planning window is 68–75°F for temperature and 7–7.2 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Black Moor Goldfish sets the larger listed base aquarium requirement at 30 gallons; the other listed minimum is 5 gallons. Black Moor Goldfish is the larger adult by the recorded maximum, reaching 6 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.
Black Moor Goldfish is a calm species associated with the mid zone and low flow. Crystal Red Shrimp is moderate, uses the bottom zone, and has a moderate flow preference. Black Moor Goldfish 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.
Black Moor Goldfish is recorded as a omnivore with intermediate care, while Crystal Red Shrimp is a omnivore with advanced care. Their listed preferred tank styles are goldfish 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.
