Corydoras habrosus is one of the 3 smallest species of Corydoras. It goes by many names, with Salt and Pepper Cory or Dainty Cory being the most common two. Reaching about 1.25", it spends more time on the substrate than the other 2 species of dwarf Cory. These are very peaceful fish that will never bother any other tankmates besides possibly fry or baby shrimp.
These are specimens ranging from about 0.5-1" long.
