It's a fish ...
Unless you're talking about a whale or a dolphin ... those are mammals.

The popular concept of a fish as an animal that has fins and scales, and lives in water, is not strictly correct. Many species of fishes such as the clingfishes lack scales, and others such as some species of eels have no fins. Some fishes such as the lungfishes can spend considerable time out of water.
All fishes have a backbone or a notochord, and all breathe using gills. Some animals that are not fish, such as the axolotls also breathe using gills. These animals however have fully formed limbs that are lacking in fishes.
A fish is a poikilothermic (cold-blooded) water-dwelling vertebrate with gills. There are over 27,000 species of fish, making them the most diverse group of vertebrates.

Well fish are actually unevolved reptiles. AS you may know, all life began in the water. Well fish were among the first multicellular animals created, and then they evolved legs to become reptiles. Those that did not stayed as fish. When classifying you may call fish invertebrates, but after that they can only be classified specifically as fish.

Although we commonly speak about "fish", this term is not one of the formal groups in the hierarchical classification of life. This is because very different vertebrates are known as fish (and even some invertebrates are dubbed "fish" = shellfish, jellyfish, etc).
Among the vertebrates, "fish" are all the primarily aquatic vertebrates that have fins instead of terrestrial limbs (i.e. feet with fingers). This includes the jawless fishes (hagfish and lampreys), the cartilaginous fishes (rays, sharks, chimaeras), and the bony fishes (ray-finned fishes, such as a catfish or perch; and lobe-finned fishes, like the lungfishes and coelacanth).
In spite of their differences, all these are animals, and none are tetrapods (which means that they cannot be reptiles or mammals, because those are categories within the Tetrapoda).

Fish is a water living animal. Only whales and dolphines are mammal but they are not fishes. The whales and dolphines are viviparus and they have horizontal tail flap. But the fish have vertical tail flap. Some fishes are amphibians.

There is indeed a catagory by species and it is ,simply, fish. But not all life in the ocean is fish. example, shark=fish dolphin=mammal fish is breathing through gill apparatus, dolphin(mammal) breathing above water as we do.
