Vertebrae: 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). |
| 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). |
