简单描述
检索表 | 型态特徵 | 形态测量图
脊椎骨: 18 - 19. Relatively low scute numbers (dorsal/ventral row, 23-24/20-21, pre-adipose scutes 2-4, usually 3), series of 4-6 distinct spots or a continuous midlateral band along the middle of the side instead of 2-3 large dark blotches; dorsal and pectoral fins not elongated in either sex; distinct stripes in dorsal and caudal fins (Ref. 52874).
Body shape (shape guide): fusiform / normal.
相当低的鳞甲数字 (背部的/腹的列, 23-24/20-21, 前脂肪的鳞甲 2-4, 通常 3), 数列 4-6个明显的斑点或一条连续的侧面中央的条纹沿着侧边的中央取代 2-3个大的黑色斑块; 背部的与胸鳍在任一性别方面不延长; 在背鳍与尾鳍鳍明显的斑纹。 (参考文献 52874)
Facultative air-breathing (Ref. 126274); Usually occurs in areas with sandy bottom, bank vegetation entering water or with marginal aquatic plants, dark, clear or slightly turbid water and limited associated fauna (Ref. 52874). Mimicked by Otocinclus mimulus; (Ref. 52874). Mimicry is unusual because the two species occupy different microhabitats and it is hypothesized to operate with a primarily visual predator moving between the microhabitats, tentatively identified as the cichlid Crenicichla lepidota (Ref. 52874).
通常出现于区域中且底部为沙地的地方, 河岸植被进入水或具有边缘的水生植物, 深色的﹐清澈的或些微混浊的水与有限制的相连动物相.(参考文献 52874) 被 Otocinclus mimulus 拟态; (参考文献 52874). 因为两者种占领不同的小环境，而且它被假定操作，所以拟态是罕见的具有一个被暂时地鉴定为丽鱼科的 Crenicichla lepidota 的在小环境之间移动的主要视觉的掠食者.(参考文献 52874)
