Introduction to Brackish Water Fish

Brackish water fish occupy a unique ecological niche, thriving in habitats where freshwater meets saltwater. This environment is characterized by varying salinity levels, making it distinct from purely freshwater or marine ecosystems. These fish species have adapted fascinating physiological traits to survive in such conditions, making them both interesting and challenging additions to aquariums.
