Freshwater fish are fish species that spend some or all of their lives in bodies of fresh water such as rivers, lakes, ponds and inland wetlands, where the salinity is less than 1.05%. These environments differ from marine habitats in many ways, especially the difference in levels of osmolarity .
In a home setting, these fish need well-oxygenated water with a pH level of 6.8 – 7.2, optimal temperatures varying between 72 and 82 °F (22 and 28 °C), and plenty of aquatic plants to give them hiding places amid their school. If properly cared for, Rainbowfish can live up to 5 years in captivity. [5]
