Unlike mammals, fish absorb oxygen directly into the blood stream at the gills. They don't have lungs so blood doesn't have to be pumped to the lungs to be oxygenated before it can be pumped round the body so they only need 2 chambers in their heart
Fish hearts have 2 main chambers: the atrium and the ventricle. Fish have the simplest hearts of all the vertebrates.
If your heart had only two chambers then oxygen-rich blood would be diluted by oxygen-poor blood and your body would not get oxygen as efficiently as it does. Efficient circulation is necessary for mammals such as humans to maintain a high metabolic rate.
Yes, fish have hearts. All animals have hearts.

4 Yes, 4 is correct. But, it depends on what type of creature you're asking about. Fish: 2 total; 1 in, 1 out. Birds & Mammals: 4 total; 2 in, 2 out. Reptiles & amphibians: 3 total; 2 in, 1 out. Hope this helps : )
Fish
Jawless fish, such as lampreys and hagfish, typically have a two-chambered heart consisting of a single atrium and a single ventricle. This simpler heart structure is characteristic of agnathans, an ancient group of vertebrates.
There are 4 chambers/rooms in the heart of bird/mammal.Here are some others...Fish-2 chambers/roomsLizard-3 chambers/rooms

The heart only has 2 chambers one in the upper part and one in the lower part!

Their are 2 heart chambers.
Fish hearts don't have four chambers.

no, the superior chambers of the heart refer only to the left and right atria. the left and right ventricles would be considered the inferior chambers of the heart.
Clams have the most complex heart of the mollusks, with 3 chambers.
Sharks have 2 chambers
