Freshwater (whitewater) fishes include halibut, salmon, and red snappers.
Birds have streamlined bodies and wings that enable them to move efficiently through the air, while fishes have hydrodynamic shapes and fins that reduce water resistance, allowing them to move easily through water. These adaptations help both birds and fishes to navigate their respective environments with speed and agility.
A blue fishes habitat is in the water.

Moray Eels are Marine water fishes So in other words, they are salt water fishes
fishes. All fishes breath in the water. They cannot survive outside of water except for few fishes which have adapted to breath air like the mud skipper fish. The only reason fishes are able to breath under water is because of their gills
so that they can move smoothly
of course

Fish don't sneeze in the water
Marine fishes drink seawater to maintain their osmotic balance in a hypertonic environment. Unlike freshwater fishes, which absorb water through their skin and gills due to lower external salinity, marine fishes lose water to their saline surroundings and must actively intake water to prevent dehydration. They have specialized kidneys and gills that help excrete excess salt while retaining water, allowing them to thrive in their saline habitat.
- streamline bodies - dorsal, pectoral, anal fins which help move faster in water - strong muscular stomachs that make digestion easy
