Orinoco Big Spot Pleco (Hypancistrus contradens)


The Orinoco Big Spot or Polka-Dot Pleco is one of several small spotted species of Hypancistrus found in the Orinoco and Negro basins in South America. This species is distinguished by its large number of large, yellowish spots and is one of the more colorful pleco species found in the soft, acidic waters of the Orinoco and its tributaries in Colombia and Venezuela. Like its relatives, they prefer warm, slightly soft water and are sensitive to poor water quality so regular water changes are a must. They should be fed a varied diet high in proteins, including frozen bloodworms, sinking prepared foods, and Repashy gel diet.
