IdentificationMost amphiliid species are found in fast-flowing water of clear, rocky streams at high elevations or rapids of large lowland rivers (Berra 2001; Roberts 2003).basins (Seegers et al. 2003). Species of Amphilius are adapted for fast flow and rocky habitats (Skelton 1986). Morphological adaptations for these habitats include expanded pectoral and pelvic fins with a thickened first ray, depressed body, dorsally directed eyes and reduced swim bladder (Skelton 1986; Walsh et al. 2000). The large pelvic fins form, in conjunction with the body, a feeble sucking disc that enables the fish to cling to rocks (Jackson 1961b).

Body variably mottled and with 5 dark saddles which are connected by a broad stripe laterally.Light brown below.Dorsal and anal fins light brown with dark band. Adipose fin dark brown, cream-colored on the outer edges.Pectoral and pelvic fins brown on top, light yellow under with dark band. Caudal brown with a cream patch and upper and lower lobe tips are cream. Caudal color is asymmetrical the lower lobe having slightly more pigment.
