Mollies naturally live in brackish waters where rivers and oceans meet. Sea fish steadily lose water â through the skin, gills, urine, and excrement. This type is called euryhaline fish. They are so highly adapted to their environment that changing freshwater to saltwater (and vice versa) is disastrous for them. Fish that can tolerate only very narrow ranges of salinity (such freshwater fish as goldfish and such saltwater fish as tuna) are known as stenohaline species. Saltwater.

Due to osmosis, fish need to osmoregulate, which maintains the right amount of water in their bodies. The same process of changing water in a marine aquarium can be dangerous and destructive for its inhabitants and requires a more complicated procedure. Despite fish living in water, they can be at risk of becoming dehydrated (or more logically, over-hydrated).
