Fish, like all species, are always evolving. Most of these tiny adaptations will be failures that do not add to the species' survival rate (meaning they fail to survive long enough to breed and cannot pass on the adaptation to their offspring). But if you are asking when did fish first appear, the first fish appeared in the Cambrian Period about 510 million years ago.
The first fish appeared around 500 million years ago in the Paleozoic Era. These early fish were primitive jawless fish, and they evolved into the diverse array of fish species we have today.
According to scientists, the first fish appeared on earth about 530 million years ago.
It depends on your definition of fish of course but free-swiming chordates have been found in the burgess shale fossils which puts them back in the pre-cambriam.
