Seven Fish That Can Survive in Fresh and Salt Water All fish, whether they live in salt water or fresh water, must maintain a certain level of salinity in their bloodstream to survive. Surprisingly however, 40 percent of the 30,000 species of fish dwell in fresh waters. I have heard that Mollies are able to acclimate to reef aquariums, so I'm wondering if there are any others. With the resilience of the tilapia fish, these species are the leading candidates to survive this type of environment. There are two different types of euryhaline fish. However, there are certain species of fishes who can survive in both freshwater and saltwater. A favorite among aquaponic practitioners raising fish and vegetables for food consumption is the Mozambique tilapia. Some examples of these fish are: Fish that are able to live in both freshwater and saltwater are called euryhaline fish. Many saltwater fish can survive extended periods down to a SG as low as 1.005, but below that rapid death is somewhat common. Image modified by Biezl.

When a saltwater fish are thrown into freshwater, the body of the saltwater fish is hypertonic to the freshwater. Even as a stenohaline species, most freshwater fish will accept of a wider range of water parameters, compared to saltwater fish. This is a very high proportion of species density given the small area that the bodies of freshwater actually covers. This process of controlling the flow of water across their body is called osmoregulation. And with the right variety, tilapia can live in saltwater.
