大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 12.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 7247)
背棘 (總數) : 13; 背的軟條 (總數) : 14 - 16; 臀棘: 2; 臀鰭軟條: 12 - 14. Diagnosis: Body and median fins generally brown to nearly black; body paler ventrally; fins grading to smoky gray distally. Margin of scales on sides with blackish streak, appearing as series of transverse bands; few small blue spots scattered on head and sides. Pelvic and anal fins bright blue anteriorly. Lips dusky brown (Ref. 510). Body depth 1.7-2.2 in SL (Ref. 90102).
身體與中央的鰭通常褐色到幾乎黑色; 身體腹側灰白的; 鰭漸層色到煙灰色的末梢部地。 在側邊上的鱗片的邊緣有黑色的條紋, 呈現成列的橫紋; 少數小的藍色斑點散佈在頭部與側邊上。 腹鰭與臀鰭淡藍色前面地。 形態上近似 S. fasciolatus ，但是 S. obreptus 在眶下骨與前鰓蓋骨邊緣上有發展良好的鋸齒, 在後部輪廓軟的背部更尖和更有角的, 與它棲息地不同。 唇暗褐色的。
Adults occur close to shore in rocky or dead reef areas where visibility is often reduced due to silting and wave action. Territorial, they maintain and 'weed' filamentous algae patches growing on dead coral (Ref. 9710). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
生存於接近在能見度時常縮小的岩石的或者死珊瑚礁區域中的海岸由於淤泥與波浪活動。 領域性，維持與 '雜草' 菌絲藻區塊生長在死珊瑚上.(參考文獻 9710)
