Summary:

Distribution

Known from the northern Great Barrier Reef to about Moreton Bay, Queensland, and reefs in the Coral Sea. Elsewhere the species occurs in the east-Indo-west-central Pacific. Often seen perching on coral heads on reef flats and in lagoons, at depths to 11 m - usually in areas not exposed to heavy surge.

Features

Dorsal fin XII-XIII, (rarely XIII), 13-15; Anal fin II, 15-17; Pectoral fin 12-14 (rarely 12 or 14); Segmented caudal-fin rays 13; Vertebrae 10 + 21-23. 
Dorsal fin deeply incised between spinous and segmented-ray areas. Dentary incisor teeth which includes anterior canines very similar in appearance from incisors, 46-54 in males and 48 to 56 in females, averaging more in females than males; posterior canines 0 or 1 (usually 1). 
Lateral line without vertical pairs of pores, extending posteriorly to point between vertical from interspace between 9th and 10th spines and vertical from base of 11th dorsal-fin spine (rarely anterior to base of 10th spine). With cirrus on posterior rim of anterior nostril; absent on anterior rim. 

Colour

Body pale with a distinct, dark Y-shaped mark on the fleshy pectoral-fin base, a black "chin-strap", fine spots sparsely peppering the rear of the body, a dark horizontal stripe from the rear of the eye above the gill cover, a dark lower lip followed by a conspicuous pale salmon-pink area on the chin and a dark dusky area behind.

Biology

Females lay demersal eggs that are attached to the bottom via a filamentous, adhesive pad or pedestal. The larvae are planktonic, often found in shallow, coastal waters.

Fisheries

Semi-translucent grey body, pale orange eyes, black ‘chinstrap’, dark V-shaped mark on pectoral fin base, faint spots and dashes in rows along body, and fine black spots scattered on rear half of body. Also has a darker colour form with a more heavily patterned body, black spots on rear of body are still present though.

Remarks

Small family groups usually live atop large bommies and coral heads, perching on their pectoral and pelvic fins when not feeding.

Similar Species

The similar Ecsenius yaeyamensis has larger white spots on the body rather than fine black spots, along with distinct black dashes behind the eye.

Etymology

The specific name stictus is from the Greek word meaning spotted, in reference to the fine dark spots on the body that distinguish the species.
