Common Name
Chubby Pleco, L056, Tocantins River locality
Scientific name
Parancistrus aurantiacus
Origin and Habitat
Native to the Amazon basin with verified records from the Tocantins River system. In the Tocantins it favors rocky margins and runs with moderate to fast current, clear water, and high oxygen. Crevices among granite and cobble, plus under ledges, provide daytime shelter, with foraging along rock faces toward dusk. Collection notes and trade reports frequently specify the Tocantins, while some sources also list the species from neighboring clearwater systems. Locality labels help aquarists match flow, chemistry, and look.

This pleco is a great addition to my Amazon tank. It’s active during the evening and hides well during the day. The water flow and rock setup match the Tocantins habitat closely, which makes a big difference in its behavior.
Ruth Carr –
I’ve had this pleco for three months now. It’s calm and doesn’t bother other fish. The tank setup with rocks and current is essential—without it, it wouldn’t settle in as well.
Leonard Russell –
The description of the Tocantins habitat helped me set up the tank properly. The pleco is very active at night and seems to enjoy the rocky areas. Water quality has stayed stable since adding it.
