The French angelfish looks completely different as a juvenile than as an adult: young fish are black with bright yellow stripes, while adults turn grayish-black with yellow-edged scales. It also acts as a cleaner fish, picking parasites off other fish.
What defines this group — Reef fish
The bony fish that live against coral and rock: the living backdrop of almost every dive.
A bony skeleton, scales, and a rigid gill cover closing over the gills.
A swim bladder acts as a float: they hold their depth without swimming.
Many change colour, pattern — sometimes even sex — over the course of their life.
