Size 265mm or 10.4" SL. Find near, nearer or same sized spp.
Identification The genus Farlowella is distinguished by its elongate and slender body with a pronounced rostrum (of variable length), having the dorsal fin located near the middle of the body and only slightly anterior to the anal fin (vs. having the dorsal fin conspicuously closer to the head than the tail, and significantly further anterior than the anal fin), and having a brownish color with two lateral dark stripes beginning at the tip of the rostrum, passing through the eyes and ending at the tail. A key to the genus can be found here.
