Physical Description

As with other Aponogids, the PJ cardinal has 2 distinct dorsal fins. The rearward portion of the body has several horizontal rows of purplish 'polka dots'. A black band is then found around the body at the front half of the first dorsal fin, through the pelvic fins. The head area is yellowish.

As the fish matures, the black band becomes grey, or shot with white. Red margins develop around the pelvic and first dorsal fins.
