背的軟條 (總數) : 12; 臀棘: 1; 臀鰭軟條: 4; 脊椎骨: 31 - 32. Sides of body with 3-5 bold longitudinal stripes. Pectoral fin with bold submarginal stripe, otherwise with reticulated marks. Pelvic fin with 3 bold stripes. Dorsal surface of head, body and paired fins otherwise with bold, connected polygonal markings or reticulations with dark outlines and pale centers. Pectoral fin branched rays 19-21. Pelvic fin branched rays 19 (Ref. 38650). Differs from other species by the following combination of characters: posterior part of paired fins with 1-2 bold concentric bands; pelvic-fin origin below dorsal-fin origin; pectoral-fin origin behind corner of mouth; pelvic fin reaching anal-fin origin; no cavity around mouth; small soft elevated patches of fine tubercles on first pectoral-fin rays in males, tubercles on simple pectoral-fin ray not enlarged; no cavity around mouth; no skin-fold between oropectoral membrane and ventral surface of head; and 38-49 lateral line scales (Ref. 40433).
Body shape (shape guide): elongated.
身體側邊有三個 -5條顯著的縱向斑紋。 胸鰭有顯著的靠近邊緣的斑紋,不一樣地以網狀的標誌。 腹鰭有 3 顯著的斑紋。 頭部背面, 身體與偶鰭不一樣地具有顯著的, 連接了多角形的斑紋或者網眼有深色的輪廓與灰白的中心。 胸鰭分支條 19-21. 腹鰭分支條 19.(參考文獻 38650) 在組合特徵之後有別於其他種藉由: 偶鰭的較後面的部分有 1-2 個顯著的同中心的條紋; 在背鰭起點之下的腹鰭起點; 胸鰭起點在嘴角後面; 腹鰭達成臀鰭起源; 嘴的周圍沒有洞; 在雄性中的在第一個胸鰭鰭條上的細小瘤的小軟升高區塊, 在不被增大的單一的胸鰭鰭條上的小瘤; 嘴的周圍沒有洞; 沒有皮膚-在 oropectoral 薄膜與頭部的腹面之間摺疊; 而且 38-49個側線鱗片.(參考文獻 40433)
Rheophilous, inhabits rapids and riffles. Found in small streams with large and deep pools covered by submerged plants, provided that small riffles are present between these pools. Occurs also in high gradient streams consisting almost exclusively of waterfalls; in larger rivers, at the upper extremity of riffles where current velocity do not exceed 0.2 m/sec, as well as habitats with high water velocities exceeding 1 m/sec. Often associated with Annamia normani, Balitora sp., Schistura spp., Glyptothorax spp., Anguilla marmorata, and Rhinogobius spp. Stomach contents include benthic invertebrates and algae. Observed to be active during daytime searching in the periphyton on both horizontal and vertical surfaces of stones probably searching for aquatic invertebrates (Ref. 40433). Commonly found in aquarium trade in Finland (Länsman, pers. comm., 25/03/2010, Ref. to find).
喜愛急流的, 居住於急流與急流。 發現於小的溪流有大的被水下的植物蓋著的且深水池, 提供哪一小的急流在這些水池之間出現。 在瀑布組成幾乎只的高落差的溪流也生存; 在較大的河中, 以水流速度不超過 0.2 公尺/秒的急流的最上層, 以及水流速度高達超過 1 m/sec 的棲地時常伴隨著 Annamia normani ， Balitora sp. ， Schistura spp。, Glyptothorax spp。, 安圭拉 marmorata, 與 Rhinogobius spp。 胃內含物包括底棲的無脊椎動物與藻類。 觀察是活躍的在白天期間可能在石頭的垂直面與水平面上的固著生物中尋找尋找水生無脊椎動物。 (參考文獻 40433)
