Can a Pygmy Corydoras Survive in Your Tank? Totally Impossible Until Now! If you’re a passionate aquarium hobbyist, chances are you’ve come across the charming Pygmy Corydoras (Corydoras pygmaeus) and wondered: Can a Pygmy Corydoras truly survive in my tank? For years, many aquarists believed this delicate little catfish simply couldn’t adapt to community setups—until recent breakthroughs changed everything. ### The Longstanding Myth: Impossible Survival? For decades, Pygmy Corys were considered too sensitive and small to thrive in standard community aquariums. Their miniscule size (just 1 inch or less), shy demeanor, and specific water quality needs led many experts to dismiss the idea of keeping them in average home tanks. Most believed they struggled to compete for food, were easily stressed, and rarely reached adulthood outside ideal, low-tech setups.
