With its distinctive appearance and peaceful nature, the Granulated Catfish adds charm to any freshwater aquarium. In this detailed description, we will explore the care requirements, tank setup, suitable tank mates, and other important aspects of keeping and appreciating Corydoras paleatus in your aquarium.

Appearance:

• Unique Pattern: The Granulated Catfish has a beautifully patterned body with a speckled or granulated appearance, featuring shades of gray, brown, and black.
• Adorable Whiskers: One of the defining features of this catfish is its pair of long, delicate whiskers, called barbels, which aid in locating food and navigating its surroundings.
• Compact Size: The Granulated Catfish typically grows to a size of around 2.5 to 3 inches (6 to 8 cm), making it suitable for smaller community aquariums.

Water Conditions:

• Temperature: Maintain the water temperature between 72°F and 78°F (22°C - 26°C) to provide the optimal conditions for Granulated Catfish.
• pH Level: Aim for a slightly acidic to neutral pH level ranging from 6.5 to 7.5.
• Water Hardness: These catfish prefer moderate water hardness, with a hardness level ranging from 2 to 15 dGH.
• Filtration and Aeration: Provide gentle filtration and moderate water movement to ensure good water quality and oxygenation.

Tank Setup:

• Tank Size: A tank with a minimum size of 20 gallons (75 liters) is recommended to accommodate a small group of Granulated Catfish. A larger tank allows for more swimming space and stability.
• Substrate: Use a fine gravel or sand substrate to mimic their natural environment and to avoid damaging their delicate barbels during foraging.
• Aquascape: Create a well-planted aquarium with plenty of hiding spots, such as caves, driftwood, and smooth rocks. Provide open areas for swimming to allow the catfish to display their natural behaviors.

Tank Mates:

• Peaceful Community Fish: Granulated Catfish are peaceful and sociable, making them compatible with a variety of small to medium-sized community fish, such as tetras, rasboras, and peaceful dwarf cichlids.
• Avoid Aggressive Fish: Avoid keeping them with large, aggressive species that may harass or intimidate the catfish. Also, be cautious of fish that may outcompete them for food.

Feeding Habit:

• Omnivorous Diet: Granulated Catfish are omnivores with a preference for small live or frozen foods. They also readily accept high-quality sinking pellets, flakes, and a variety of vegetable matter.
• Bottom Feeders: These catfish have a natural inclination to forage on the aquarium substrate, feeding on leftover food, detritus, and small invertebrates.

Care:

• Water Maintenance: Perform regular partial water changes of 25% every week to maintain excellent water quality and remove accumulated waste.
• Observation and Health: Monitor the overall health and behavior of the Granulated Catfish regularly. Look for signs of active swimming, healthy appetite, and vibrant coloration.

The Granulated Catfish, with its unique appearance and peaceful nature, is a delightful addition to any community aquarium. By providing them with the proper care, a suitable tank setup, and compatible tank mates, you can enjoy the beauty and charm of these fascinating catfish while observing their natural behaviors in your aquatic sanctuary.
