Brackish refers to the water’s salinity, or salt levels, and is essentially the ‘middle ground’ between freshwater and marine water. Naturally occurring brackish water is where fresh streams meet the ocean. This type of tank is generally easy to maintain since the inhabitants are very adaptable and can handle changes in water pH and salt levels. Do not let this change frighten you; with the right equipment and care, you will have a stunning and successful tank.
