Cirrhilabrus blatteus or the purple-boned wrasse[2] is a species of fairy wrasse native to the coasts of Egypt, Eritrea, Israel, Jordan, Saudi Arabia, Sudan, and Yemen in the Gulf of Aqaba.

The fins are stained purple using alcohol, which makes it unique in its genus.

Males are known for a purple stripe that runs down the length of the body.

Cirrhilabrus blatteus is found above rock and coral bottoms, usually within 1-2m of the substrate where it feeds on zooplankton.

The males hold territories and guard herams of females.
