Pygmy Corydoras Catfish (Corydoras pygmaeus)
The Pygmy Corydoras Catfish is one of the smallest and most charming freshwater catfish in the aquarium hobby. Known for its tiny size, silver body, and bold horizontal black stripe, this peaceful species is unique among Corydoras because it spends much of its time swimming in the middle of the water column in addition to foraging along the bottom. Their active schooling behavior and gentle nature make them a perfect addition to nano aquariums and planted community tanks.
Native to the slow-moving tributaries and flooded forest streams of the Amazon Basin in Brazil, Pygmy Corydoras thrive in densely planted aquariums with soft sand or fine gravel, driftwood, and gentle water flow. They are highly social fish and should always be kept in groups of at least six, though schools of ten or more allow them to display their most natural and entertaining behavior.
Pygmy Corydoras are omnivores that readily accept high-quality micro pellets, crushed flakes, sinking wafers, frozen baby brine shrimp, daphnia, microworms, and other small live or frozen foods. Although they help consume leftover food, they should receive dedicated feedings to ensure proper nutrition.
Their exceptionally peaceful temperament makes them ideal tank mates for Chili Rasboras, Ember Tetras, Celestial Pearl Danios, small rasboras, shrimp, snails, Otocinclus, and other gentle nano fish. They thrive in planted aquariums where they feel secure and have plenty of places to explore.
