Yoyo Loach Identification Guide

Key identification features

• Silvery to pale gold base body color
• Dark brown to black markings that form Y- and O-shaped patterns along the flanks, most distinct in juveniles and fading toward a more striped look in adults
• Elongated, moderately compressed body with a slightly arched back
• Four pairs of barbels around a small ventral mouth
• Subocular spine beneath the eye typical of botiid loaches
• Grows to about 4-6 inches (10-16 cm)

Common look-alikes

• Zebra loach — has thin, straight dark stripes on gold rather than Y/O-shaped blotches
• Clown loach — bold orange body with three thick black bands, much heavier build
• Skunk loach — plain body with a single dark stripe running along the top of the back, no Y/O markings

Where you'll see one

Native to fast-flowing, rocky rivers and streams of the Ganges and Brahmaputra river systems in India and Bangladesh. It shelters among rocks and submerged roots in well-oxygenated water and typically moves in small groups over gravel or sandy substrate.
