Overview
A small, sturdy pleco for a tank of about 115 liters with good current. It is mainly a grazer, so feed algae and spirulina wafers and blanched vegetables with some protein from sinking pellets and frozen foods for balance, and no need for wood in the diet. Territorial toward similar bottom dwellers but otherwise community safe.
In the wild
Found over granite bedrock and boulder fields in exposed, fast-flowing parts of the Orinoco and its Ventuari tributary. It grazes periphyton, the algae and microfauna film coating the rocks, so its wild diet blends vegetable matter with the small animals living in that film. Give it strong flow, high oxygen, and open rock as well as caves.
Good to know
Despite the panaque trade name it is not a Panaque and does not eat wood, sitting instead among the gold nugget plecos in the genus Baryancistrus. Described as Baryancistrus beggini, it wears a solid blue-black to slate body, sometimes with a bright fin trim. It stays compact at around 10 to 12 cm.
Did you know
The panaque name is misleading, because unlike the true royal plecos this fish does not need driftwood to digest its food.
