背的软条 (总数) : 12; 臀棘: 1; 臀鳍软条: 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).
身体侧边有三个 -5条显着的纵向斑纹。 胸鳍有显着的靠近边缘的斑纹,不一样地以网状的标志。 腹鳍有 3 显着的斑纹。 头部背面, 身体与偶鳍不一样地具有显着的, 连接了多角形的斑纹或者网眼有深色的轮廓与灰白的中心。 胸鳍分支条 19-21. 腹鳍分支条 19.(参考文献 38650)
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).
喜爱急流的, 居住于急流与急流。 出现于,小的溪流有大的被水下的植物盖着的且深水池,提供小的急流在这些水池之间出现; 高落差的溪流瀑布组成几乎只; 在较大的河中, 以水流速度不超过 0.2 公尺/秒的急流的最上层, 以及水流速度高达超过 1 m/sec 的栖地时常伴随着 Annamia normani ， Balitora sp. ， Schistura spp。, Glyptothorax spp。, 安圭拉 marmorata, 与 Rhinogobius spp。 胃内含物包括底栖的无脊椎动物与藻类。 观察是活跃的在白天期间可能在石头的垂直面与水平面上的固着生物中寻找寻找水生无脊椎动物。 (参考文献 40433)
