Salween Grazer

About

Found in the Salween river basin of Asia, Garra salweenica is one of many species in a sprawling and taxonomically complicated genus that stretches from southern China across Southeast Asia, India, the Middle East, and into Africa. The genus is so widespread and poorly resolved that new species turn up regularly while others get lumped or re-described, so the exact relationships of this fish remain a work in progress. What sets this particular species apart from its Salween neighbors is a combination of features: a brownish body, a blunt snout bearing a distinctive three-lobed fleshy proboscis, a row of dark spots along the base of the central dorsal-fin rays, longitudinal stripes toward the rear of the body, and dark markings at the tips of the caudal-fin lobes. Like all members of its group, it possesses a modified lower lip that forms a sucker-like adhesive disc, which it uses to anchor itself against surfaces in fast-moving water while scraping algae and biofilm from rocks. The front pectoral-fin rays are thickened and unbranched, another hallmark of the group. Growing to nearly seven inches at full size, this is a solid, active fish that should manage well for beginner keepers willing to provide appropriate flow and a well-established aquarium with plenty of grazing surfaces.
