Like all lionfish , it has red-brown-whitish stripes and fan-shaped, wide-spreading pectoral fins , the blue stripes of which lead to its German name. The 13 spines of the first "dorsal fin", which are not connected by the fin membrane, and the three spines of the anal fin are provided with poison glands. The second dorsal fin has nine soft rays, the anal fin has seven to eight. The fin spines of the first "dorsal fin" and the outer fin rays of the caudal fin are provided with filaments.
