Adolfo’s Corydoras Catfish (Corydoras adolfoi)

Adolfo’s Corydoras Catfish (Corydoras adolfoi) is a small yet striking freshwater catfish native to the Rio Negro basin in Brazil. In its natural habitat, it inhabits soft, acidic, tannin-stained blackwater tributaries and flooded forest areas, environments that provide both shelter and abundant food resources. These fish are adapted to slow-moving, shaded waters with leaf litter and submerged roots, which allow them to forage effectively using their delicate barbels. In the aquarium, replicating these conditions is key to their health and wellbeing. Maintaining a temperature range of 66.2–78.8°F (19–26°C) and a pH between 5.5 and 7.5 ensures a stable environment. Substrates of soft sand or fine gravel are essential to prevent damage to their sensitive barbels as they snuffle along the bottom in search of food. Providing ample hiding spaces with plants, driftwood, or smooth rocks also encourages natural behavior and reduces stress, while a gentle filtration system ensures clean, well-oxygenated water.

Social behavior is a defining characteristic of Adolfo’s Cory, and these fish thrive in groups of six or more. When kept in appropriate shoals, they display engaging group dynamics, foraging cooperatively and occasionally darting around the tank in coordinated movements. Smaller community tanks can benefit from their activity, as they help stir the substrate and prevent the accumulation of uneaten food, promoting a cleaner environment. These corydoras are peaceful, making them compatible with other non-aggressive fish such as small tetras or rasboras. Their diet in captivity should reflect their omnivorous tendencies: high-quality sinking pellets or wafers, complemented with occasional frozen foods such as bloodworms or brine shrimp, provide the nutrition needed for vibrant color and active behavior. Their hardy nature and adaptability make them suitable for aquarists of varying experience levels, although attention to water quality and group composition is essential for optimal health.

Beyond their scientific appeal, Adolfo’s Cory carries undeniable visual charm that makes them a sought-after addition to any freshwater aquarium. Their slender bodies, subtle coloration, and distinctive orange head patches paired with a contrasting black dorsal saddle create an elegant display along the bottom layer. They ship individually bagged to ensure minimal stress and peak health during transport, making it easy to introduce them safely into your tank. These fish are not only a testament to the beauty of nature but also a rare opportunity for collectors, as high-quality specimens often move quickly once available. For aquarists looking to combine striking aesthetics with engaging social behavior in a community tank, Corydoras adolfoi delivers both reliability and character, ensuring a lively, visually captivating, and harmonious aquatic environment. These fish ship individually bagged, one per bag.
