The water that the fish swims in passes over the gills - these work like our own lungs - taking in oxygen, and expelling carbon dioxide.
This is why you need to change the water in the tank on a regular basis - because the level of carbon dioxide increases daily.
no, Fish like all animals breathe in Oxygen and out Carbon Dioxide.

either gills or stomata
Fish are like humans in the way that they need oxygen. Fish breathe in dissolved oxygen and pass out carbon dioxide.
Fishes use Oxygen in water. They absorb the absorbed oxygen through their gills.
Yes they do. Its part of the carbon cycle. When plants give off carbon dioxide, animals breath it in, when they die, scavengers eat them then decomposer breaks the dead carcasses back into the basic materials.
GILLS!!
