Clark's anemonefish is the least picky of all clownfish species: it can settle into around ten different anemone species, compared to just one or two for most of its relatives. This flexibility lets it range across a much wider geographic area.
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.
