Paraplesiops is a genus containing five largely allopatricspeciesoffishes in the longfin, or roundhead, family Plesiopidae, commonly known as blue devils, bluedevils, or blue devilfish because of their colouration. The genus is most similar to the tropical genera Plesiops and Fraudella. It is restricted to subtropical and temperate rocky and coral reefs in Australian waters. Its species are mostly cryptic, occurring in submarine caves, crevices and under rocky ledges.[1]
Paraplesiops often hide unless food is available, they are very friendly fish unless around their prey. They eat small fish or crustaceans.[2]
