Fish can be divided into two broad categories on the basis of their breeding behavior.

Fish are the oldest of all vertebrates (animals with backbones), with an ancestry dating back more than 500 million years. However, the earliest fish to appear in the world’s oceans were very different from those seen today, since they had no jaws or scales. They lacked specialized fins, so they relied solely on tail movements to propel them through the water. Internally, their spine was made of cartilage, rather than bone.

It probably began in China with the domestication of goldfish and koi and has spread worldwide with advances in aquarium technology and transportation. Today’s aquatic industry produces a vast range of products to make fishkeeping more rewarding than ever before.
