Scientific Name

The Dainty Cory, scientifically known as Corydoras habrosus, is a diminutive freshwater fish that captures the hearts of aquarists with its delicate charm. As a member of the Callichthyidae family, this species proudly claims its origins in the abundant ecosystems of the Amazon, particularly thriving in the Madeira River basin of Brazil.

In 1966, the Dainty Cory was first described by Joachim Knaack, a reputed German biologist. He chose the species name ‘habrosus’, rooted in Latin, conveying the notions of grace and finesse that the fish exhibits. Although its dainty appearance often leads to confusion with Corydoras hastatus, another small-scale Corydoras species, the Dainty Cory holds its unique place among freshwater enthusiasts for its unassuming elegance and playful behavior.

With its scientific nomenclature, C. habrosus not only reflects its physical attributes but also its fascinating journey from the lush Amazonian waters to the intimate setting of home aquariums worldwide. The Dainty Cory continues to be a delightful subject of discovery and enjoyment within the aquatic community.

Average Size

When considering incorporating the Dainty Cory, or Corydoras habrosus, into your aquarium, it is essential to understand the size-related requirements of these peaceful schooling fish. As adults, they reach an average size of 1.4 inches (3.5 cm), which places them on the smaller end of the freshwater fish spectrum. Upon purchase, these charming creatures are typically even smaller, generally measuring between 3/4 – 1 inch (1.9 – 2.5 cm).

These dimensions lend themselves well to life in cozy aquatic spaces. The recommended tank length for comfortably housing a group of Dainty Corys is at least 20 inches (50 cm), allowing them to explore and exhibit natural behaviors while still being manageable for most home aquarists.

Closely related is the Pygmy Cory, C. pygmaeus, also known as Dwarf catfish. It sizes up comparably, with an adult average size of up to 1.5 inches (3 cm), and shares the long-lived nature of the Dainty Cory, with both species potentially reaching a lifespan of 4 years in a well-maintained habitat.
