Axelrod's Cory (Corydoras Axelrodi)
 
The Axelrod's Cory, also known as the Pink Corydoras, is a charming species renowned for its silver body with a striking black stripe running from its eyes to its caudal fin. It further boasts pinkish-green cheeks and three dark horizontal stripes along its body, reaching a full length of approximately 2 inches when mature.
Affectionately termed Cory Cats, Corydoras are prized for their small size, peaceful demeanor, and diligent scavenging behavior, making them popular among aquarists. With their sociable nature and playful antics, they add vibrancy to any tank. Corydoras are best kept in groups of 5-6 individuals of the same species, as they exhibit schooling behavior and thrive in the company of their own kind.
Suitable tankmates for Corydoras include small to medium-sized, non-aggressive fish that occupy the middle and upper levels of the tank, such as tetras, rasboras, guppies, and peaceful barbs. Non-aggressive bottom dwellers like loaches and otocinclus can also coexist peacefully, provided the tank is spacious enough to accommodate all inhabitants comfortably. However, aggressive or territorial fish, particularly larger species like cichlids, should be avoided to prevent conflicts.
In terms of diet, Corydoras are omnivorous, primarily scavenging for food along the tank bottom. They enjoy a varied diet consisting of sinking shrimp pellets, catfish pellets, algae wafers, and bloodworm sticks. Additionally, offering frozen bloodworms or daphnia as occasional treats twice a week enhances their nutritional intake.
Creating an ideal habitat for Corydoras involves providing well-oxygenated water with moderate flow and a soft sandy substrate reminiscent of their natural riverbed habitats. Ample hiding spots using driftwood, rocks, caves, and sturdy live plants like Java Fern and Anubias are essential for their well-being. These plants not only offer cover but also contribute to the tank's aesthetics.
For a 30-gallon aquarium, consider stocking 5 cory catfish at the bottom, a school of 6 small tetras in the middle layer, and a pair of Honey Gouramis as centerpiece fish, ensuring a harmonious and visually appealing setup.
Maintaining consistent water parameters is crucial for Corydoras' health and well-being. Aim for a pH range of 5.5-7.5, hardness within 2-12 dGH, and a temperature between 72-79°F (22-26°C). Regular monitoring and adjustments will ensure a thriving aquatic environment for these delightful fish.
