Overview
The Orinoco peckoltia is a small, well-mannered pleco for the bottom of a calm community tank. It is best kept by someone with a little experience.
Did you know
The Orinoco peckoltia is named for the ichthyologist Nathan Lujan. He has collected and described many of the fancy plecos of the Orinoco himself. In time, his colleagues pinned his name on one of them.
Caring for the Orinoco peckoltia
Give an Orinoco peckoltia at least 29 gal (110 L). Furnish it with driftwood, rounded stones and caves over a sand or fine gravel floor. It keeps to the caves and driftwood and comes out to forage.
Keep the water soft and warm, at 77 to 84°F (25 to 29°C) with a pH of 5.5 to 7.0. A gentle, clean current suits it. Feed a varied diet of sinking wafers, pellets and vegetables, with occasional frozen foods.
It is best kept singly, though it is peaceful and undemanding in a community. House it with small, calm tank mates rather than boisterous ones. It is an egg layer, and breeding it is of moderate difficulty.
Good to know
Peckoltia lujani is a small loricariid marked with fine, worm-like lines. It is sold as L127 and was known in the hobby for years before its formal description in 2015.
In the wild
The Orinoco peckoltia comes from the Orinoco and Meta river basins of Venezuela and Colombia. These are warm rivers with wood and rock.
