Blue-eyed plec
The blue-eyed plec is a herbivorous freshwater armored catfish endemic to Colombia where it occurs in the Cauca and Magdalena River basins. It is distinguished from many loricariids by being dark grey to black and having bright, turquoise-coloured eyes. Like other species of the genus Panaque, P. cochliodon feeds primarily on submerged wood. Blue-eyed plecs grow to about in length and, like other Panaque species, they are clumsy swimmers adapted to staying close the substrate, using their sucker-like mouths to hold on to submerged rocks and wood.
