Fishes have two chambered hearts they have only one atrium and one ventricle.
The hearts of fishes are two chambered hearts, they have only one atrium and one ventricle. In that respect the fish heart resembles the embryonic condition of all other vertebrate animals. Afferent branchial arteries develop from aortic arches 3, 4, 5, and 6 to supply blood to the gills.

Fish has a two-chambered heart. The heart has a single atrium and ventricle. Atrium takes the blood from the body and ventricle is responsible for pumping out the blood that has entered the heart. The ventricle pumps the deoxygenated blood to the gills and the oxygen from the surrounding water is given to the blood.
Fish are vertebrates that have two-chambered hearts consisting of a single atrium and a single ventricle. The atrium is responsible for taking in returning blood from the body, while the ventricle's duty is to pump out blood that has entered the heart.In fish, the ventricle pumps the oxygenated blood to the gills and the blood is given fresh oxygen from the surrounding water. Due to the simplistic design of the two-chambered heart, a lower amount of oxygen reaches body tissues at any one time in comparison to three-chambered and four-chambered hearts. Fish have lower metabolic capacity than these animals. The metabolic needs, however, of fish are not as demanding as those of warm-blooded animals.
