Relevant Information:

Like all the orange-blotched Corydoras from the upper Rio Negro drainage, Corydoras nijsseni is very  variable in the black parts of the colour pattern. There are forms with broad and forms with very narrow  stripes, depending on the locality. The other orange spotted species which are syntopic with Corydoras nijsseni mostly show the same variation. The form with a very broad band (only in males), has been erroneously given the C-number C111. Aquarium care: This is akin to most of this genus, very peaceful, and would be best housed with small to medium tank mates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. Diet: A good quality flake food and tablet food for adults with sporadic feedings of frozen or live food will keep your Corydoras in good health.
