Additionally, goldfish produce a higher volume of waste, which can elevate ammonia levels in a tank that cannot accommodate such a bioload efficiently. Therefore, accommodating both fish in the same tank may create an unhealthy environment for either or both species.
One benefit of keeping goldfish separately is that they can live long and healthy lives in appropriate setups. The average lifespan of goldfish can exceed 10 years with proper care. Research by scientists like Michael E. Basler (2015) indicates that goldfish are adaptable and can thrive in tanks as small as 20 gallons, provided water quality is managed well. This allows fishkeepers to create ideal environments for goldfish without mixing species that may cause compatibility issues.
However, the drawbacks of housing goldfish with tropical fish include increased tank maintenance. Goldfish require a larger tank due to their size and waste production. A study done by aquatic biologist Dr. Andrew Fishman (2020) reveals that when goldfish are kept with tropical species, the waste can lead to spikes in toxins, causing stress and illness. Furthermore, goldfish are known to be fin nippers, which may harass delicate tropical fish.
For those considering an aquarium setup, it is recommended to house goldfish with other goldfish or specific cold-water species. If keeping tropical fish, ensure the tank temperature and water quality meet their specific needs. Always research the compatibility of each species before introducing them to the same environment, and consider a larger tank to accommodate the needs of all fish effectively.
