[[File:Thalassoma lunare.jpg|thumb|The [[moon wrasse]], pictured here at the Great Barrier Reef, is one of the most abundant fish species at the Houtman Abrolhos]]

At last count, a total of 389 species of fish have been recorded from the Houtman Abrolhos. 16 species occur in very large numbers; in decreasing order of abundance, these are:<ref name="Hutchins 1997b">{{cite book | author = Hutchins, J Barry | year = 1997 | chapter = Checklist of fishes of the Houtman Abrolhos Islands, Western Australia | title = The Marine Flora and Fauna of the Houtman Abrolhos Islands, Western Australia | volume= 1 | editor = Wells, FE | publisher = Western Australian Museum | pages = 239–53}}</ref>

About two-thirds of the total number of species are tropical in distribution, the remainder being subtropical or warm-temperate. This ratio also holds for the most abundant species, eleven of the sixteen species being tropical.<ref name = "Hutchins 1997b"/> On the other hand, over 70% of tropical species occur in extremely low numbers, so low in fact that they are thought not to maintain breeding populations at the Abrolhos; rather, populations are maintained by [[larva]]e carried to the islands by the Leeuwin Current from populations further north.<ref name="Hutchins 1997a">{{cite book | author = Hutchins, J.
