Can I keep both freshwater and saltwater fish in the same aquarium?

Unfortunately, freshwater and saltwater fish have different environmental needs, so they cannot be kept in the same tank. • If you're looking for diversity, you might consider setting up two separate tanks, each tailored to its specific type of fish. This allows you to fully cater to the needs of both ecosystems. • When planning, always do your research on the specific requirements of the fish species you want to keep to ensure their health and happiness.
