Dorsal spines (total): 7; Dorsal soft rays (total): 9; Analspines: 2; Analsoft rays: 15 - 18

Nocturnal species which occurs inshore (Ref. 75154). Inhabits continental and insular shelves; on coral and rocky reefs in sheltered bays and lagoon, patch reefs, with muddy, sandy and silty bottoms or coral rubble, and mangroves (Ref. 54391); typically forming dense aggregations at the entrance of caves (Ref. 1602, 48635) and among branching corals (Ref. 2334). Exhibits the black gut phenomenon. In nocturnal predators, it appears to serve to conceal bioluminiscent prey in the stomach cavity (Ref. 46685).

(4-8)+(14-18)；BD. 2.3-2.5，HL. 2.6-2.7 in SL。體銀白，散布黑色素胞；體側具有20-23條的橘紅色窄曲橫紋，鰓蓋瓣後方側線下方的前2條窄曲橫紋有時會擴散延長而形成一形狀不規則的寬橘紅斑。頰部具暗點，有時會擴大而形成頰斑。尾柄眼點經常大且易區別，有時呈擴散狀，或稍淡而不顯。由吻端到眼前緣有黃線，其上下各有一藍紋延伸至眼上下緣。原記載之橫紋長鰭天竺鯛(/Archamia dispilus/)為其同種異名。

主要棲息於近岸海灣或潟湖內之珊瑚礁區。群居性，以浮游動物或其它底棲無脊椎動物為食。本種魚通常與其它長鰭天竺鯛群中混游。

Taeniamia fucata, commonly known as the orange-lined- or painted cardinalfish, is a marine fish native to reefs from northern Australia and New Guinea, across the Indian Ocean to the east coast of Africa, and Pacific Ocean to Marshall Islands, Samoa, Tonga, and the Ryukyu Islands. It was known as Archamia fucata until 2013. FishBase treats T. sansibaricus as synonymous with T. fucata. but T. sansibaricus is recognised as valid by the Catalog of Fishes:
