Freshwater fish live in water that’s less salty than their bodies. Which means water is constantly moving into them through their gills and skin. So do freshwater fish drink water? Not really! 💧🐟 Instead of gulping it down like saltwater fish, freshwater fish absorb water naturally through a process called osmosis. Because water is always entering their bodies this way, they have special adaptations that help them stay balanced and healthy. It’s all about maintaining the perfect salt-to-water
