If you are asking what era the fish ORIGINATED, then your answer is the Cambrian Period, which was during the Paleozoic Era (544-245 million years ago). They started off as invertebrates, however. The first vertebrate that was a fish was the jawless fish in the Ordovician period. The first vertebrate that was a fish was the jawed fish in the Silurian period.
Fish first developed in the Paleozoic Era
Fish are animals that have been around for millions of years and are currently part of the modern era, known as the Cenozoic era. They have evolved and adapted over time to inhabit a wide variety of aquatic environments around the world.

Until the modern era, fish detection was done primarily by the eye. The twentieth century introduced new methods of looking for fish

The Devonian era is a geological period that occurred approximately 419 million to 359 million years ago. It is known for the diversification of marine life, including the appearance of early fish and amphibians, as well as the spread of forests on land.
The Paleozoic era was from 540 million years ago to about 245 million years ago. After that came the Mesozoic era, and that lasted from the end of the Paleozoic to 65 million years ago, when the earth entered the Cenozoic era.
Fish, reptiles, and amphibians, originated in that order during the Paleozoic era.
The ichthyosaur was a large marine reptile that resembled a fish in the Mesozoic Era. It had a streamlined body shape, fins for swimming, and sharp teeth for hunting fish and squid. Ichthyosaurs were highly adapted to a marine lifestyle and were some of the top predators in the oceans during their time.
During the Paleozoic Era, the first land plants, insects, fish, amphibians, and reptiles evolved. This era also saw the evolution of early mammals and the diversification of life in the oceans. The end of the Paleozoic Era was marked by a mass extinction event that wiped out many species, paving the way for the rise of new organisms in the following eras.
