Reef fish arrived in 2 waves

A new study reveals that reef fish diversified into two distinct groups of fish, with the first group arriving around 70-90 million years ago, during a time when coral reefs were built by mollusks called rudists. By 50 million years ago, modern coral reefs and their inhabitants had largely taken shape.
