Coloration: in life: fish olive-green or rusty-brown dorsally, paler ventrally; small, blue ocelli scattered over flanks and dorsum, and some oblique, black bands may be present on dorsal part of flanks (Ref. 57403, 79590). 1st dorsal fin is dark on its anterior margin and has a bright blue longitudinal band near its distal margin; 2nd dorsal fin has 2, narrow, bluish-white longitudinal bands on its upper half (Ref. 57403). Anal fin pale or white, and sometimes slightly mottled with fine, dark spots (Ref. 79590). Pectoral fins dark on outer (lateral) surface, with pale distal margins, and lighter on inner (medial) surface, particularly ventrally; pelvic fins whitish on ventral surface but darker on dorsal surface, with pale margins; caudal fin dark (Ref. 57403, 79590). Preserved specimens: dark brown/violet on head, dorsum and flanks; chin pale or mottled gray; ventral body surface pale whitish-yellow (Ref. 57403, 79590). 1st dorsal fin grayish with a black band near distal margin, bordered dorsally and ventrally by a narrow white band; 2nd dorsal fin with a brown margin and a black stripe running along upper portion of fin, this stripe bordered dorsally and ventrally by a narrow white band (Ref. 57403). Anal fin pale or white (Ref. 57403), sometimes slightly mottled with fine, dark spots (Ref. 57403). Caudal fin dark brown on its dorsal part, whitish on its ventral part (Ref. 57403).
眼以低的眼瞼摺層伸出而且靠攏在一起; 深地的吻; 嘴水平的。 兩個分開的背鰭, 第一個高的, 藉由 11根柔韌有彈性的棘, 第二個低的, 它的基底長度超過從末端到臀鰭起點的距離; 胸鰭有一個長的肌肉葉; 腹鰭越過基底聯合了; 尾鰭有低的鰭條短, 與矮胖的。 色彩是褐色的有斜深色的橫帶，腹面顏色淡的; 背鰭具有一個寬的末梢部的縱向深色條紋與灰白的邊緣。
Facultative air-breathing (Ref. 126274); Found on muddy substrates and in brackish waters of estuaries, lagoons and mangrove swamps (Ref. 79590). Occasionally found in freshwater, but always close to the shore (Ref. 57403, 79590). Amphibious air-breather (Ref. 31184) that skips or walks on sand or mud in search of food; that is, on exposed intertidal mud flats of estuarine mangrove swamps. Adult feed chiefly on arthropods (crabs, insects, etc.) of the mud surface. Also included in the diet is the white mangrove, Avicennia nitida (Ref. 3026). Spawn in burrows (Ref. 3657). Maximum reported total length 165 mm; reports of larger specimens, up to 250 mm TL, are probably misidentifications of other species (Ref. 79590).
