Relevant Information:

Aquarium care: The Pseudancistrus genera are not the easiest to maintain in the aquarium as they will need pristine water conditions with well filtered water which should not be too hard. Warm water should be the norm. Adult males are very territorial and will not get on with other large Loricariid catfish. Sexual differences: Males have a broad head and posses long bristles along the edge of the snout. Diet: Aufwuch grazer, mainly vegetarian, with lettuce, spinach, cucumber and courgette (zucchini), vegetarian flake and tablets. Will eat other foods also such as insect larvae, zooplankton and soft wood but will need to be kept on a mainly green diet.

Common Name:





Loricariidae ycipitidae


South America: Upper Potaro River basin, tributary of middle Essequibo River, Guyana.
