Pygmy cories look just like most other Corydora, with the exception of the fact that they don’t grow bigger than 1 inch (2,5 cm). They are often mislabeled as Corydoras hastatus or Corydoras habrosus. Not surprising: they’re easily confused with one another and the terms ‘dwarf Corydoras’ and ‘pygmy Corydoras’ are used interchangeably. Even aquarium stores might not always take the time to tell the species apart.
Corydoras pygmaeus can be told apart from the other two species by the stripe that runs down their entire body length. Corydoras hastatus has a black spot on the tail, while Corydoras habrosus has distinctive spots along the upper back.
The difference between female and male pygmy Corydoras is usually not too hard to tell. Females look rounder, especially when viewed from above. They are also usually a bit bigger than their male counterpart
