(Bandit) Matae Cory Catfish - Corydoras Matae

The Bandit catfish (Corydoras metae) is a peaceful, schooling freshwater fish known for the black "mask" across its eyes, originating from the Meta River basin in South America. These small, bottom-dwelling catfish are popular in aquariums, requiring soft, acidic water and a diet of sinking pellets, wafers, and live/frozen foods, and should be kept in groups of 5 or more to thrive. They are hardy and compatible with most community tank mates, but need a soft substrate like sand to protect their delicate barbels.
