Pygmy corydoras

The Pygmy Corydoras (Corydoras pygmaeus) is a small, schooling fish native to South America, specifically the Rio Madeira basin in Brazil. It exhibits a silver body coloration with a distinct, unbroken black stripe extending horizontally along the mid-lateral line from the snout to the caudal peduncle. A second, thinner black line runs along the lower portion of the body, originating behind the ventral fins and continuing into the tail. The dorsal area displays a light black or dark gray shading. Sexual dimorphism is apparent, with females typically reaching a maximum length of 2.5 cm and exhibiting a rounder, broader body shape compared to males, which typically reach 1.9 cm. Pygmy Corydoras are peaceful and well-suited to community aquariums. They thrive in planted tanks with soft, slightly acidic water and require a varied diet of small sinking foods.
