Adult Painted Sweetlips in Australian waters are slate grey coloured. The species occurs in the tropical Indo-West and Central Pacific.
Johnson et al's 2001 review of the genus Diagramma recognised five subspecies of D. pictum. Adult fish occurring in Australian waters (D. pictum labiosum) are slate grey in colouration (see image above). Adults and subadults never have yellow or orange spots and never have spots on the head forming lines.
Large yellow or orange spots are only found on other subspecies of D. pictum which occur in south-east Asia and elsewhere in the south-west Pacific (see lower image to the right and attached link for three images of D. pictum pictum from Vanuatu). These fish are blue-grey with yellow to orange spots on the head, body and fins. The spots on the head often form lines.
It is found in coastal and sandy reef areas in depths to 80 m.
The species occurs in tropical waters of the Indo-West and Central Pacific. In Australia it is known from the central coast of Western Australia, around the tropical north, and as far south on the east coast as the central coast of New South Wales.
