Mm that would be there Gils fins tails etcetc
The gills are the fishes equivalent of our lungs. They enable the fish to extract oxygen from the water.
The gills filter the oxygen from the water and let off the water like you would let off carbon dioxide when breathing out.

The gills

Fish use gills to extract oxygen from the water passing over the gills.
Gills allow the fish to extract oxygen from the water. Without oxygen, the fish would die. So the answer is TRUE.
Yes a fish can drown if they are kept in water completely devoid of oxygen and they are unable to get to the surface to desperately gasp for their lives. Fish breathe oxygen, not water, they filter oxygen out the water through their gills. If the water has no oxygen, they effectively suffocate.
Water weed takes in the carbon dioxide released by the fish and turns it into oxygen in a process called respiration. The fish in turn breathe in the oxygen and release carbon dioxide, starting the cycle again.
this is not a good site
Aquatic plants help to oxygenate the water - replacing the oxygen that's used by the fish - and the decaying fish waste.
The size of the aquarium and the number of fish living in the aquarium determine the amount of oxygen that is needed. The temperature of the water also plays an important role to determine oxygen needs of fish. If the water is above 80 degrees, the need for oxygen increases.
Some of the adaptations that allow fish to live in the water are gills, fins, and scales. The gills allow the fish to live in the water. The gills allow the fish to extract oxygen from the water. The fins allow the fish to swim through the water and help it stear itself. For the scales I'm not sure!
Because they Have Gills, and gills help them to breathe in the water. As water flows over the gills, a fine network of blood vessels can extract oxygen from the water, much like our lungs collect oxygen from the air when we breathe.
When a goldfish puts it's mouth above water frequently, this means that it is gasping for air as there is not enough oxygen in the water. To add more oxygen, placing bubble wands or stones in your tank will help the fish.
