Brackish water is a unique environment where the water has more salinity than freshwater, but not as much as seawater. It commonly occurs where fresh water meets seawater, such as where a river meets the sea. Brackish covers a range of salinity regimes and is not considered a precisely defined condition. Therefore the salinity can vary considerably. There are plenty of fish that reside in brackish water, and Finaddicts carries a wide variety of species to create this unusual aquatic environment.
