Relevant Information:

Corydoras diphyes belongs to the family Callichthyidae or Armoured Catfishes from South America; namely Paraguay, and is documented as being restricted to the tributaries of the Río Monday, Río Acaray, the right bank tributaries of the Río Paraná and a small stream at Estancia María Balén. Corydoras diphyes is also documented as being found in Brazil. It is a recently described species of Corydoras (2003). In its natural habitat Corydoras diphyes usually occurs in areas which have sandy substrates with bank vegetation entering the water. The water in which they are found varies from dark (stained with tannins) to clear or slightly turbid. This particular catfish is documented as being mimicked by Otocinclus mimulus. Aquarium Care: This is akin to most of this genus, very peaceful, and would be best housed with small to medium sized tankmates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. Best to purchase 6 individuals or more as they will be happier in a group. Diet: Readily accepts a mixed and varied diet which includes granular foods, tablet food, frozen bloodworm and good quality flake to name but a few.
