Adolfoi Cory Catfish (Corydoras adolfoi)

Corydoras adolfoi – Adolfoi Cory Catfish

The Adolfoi Cory Catfish is one of the most elegant and sought-after Corydoras in the hobby. Recognized by its crisp white body, bold black dorsal stripe, and striking orange “mask” across the head, this species is a true standout in peaceful community aquariums.

Native to the Rio Negro region of Brazil, Adolfoi Corys are active bottom dwellers that constantly sift through the substrate in search of food. They are social, peaceful, and thrive when kept in groups, making them perfect for hobbyists who appreciate natural behavior and schooling dynamics.

This species is ideal for well-maintained, soft-water setups and looks especially impressive over fine sand with driftwood and leaf litter.

Tank Size

• Minimum tank size: 20 gallons

• Recommended: 29 gallons or larger for a proper group

• Group size: Keep 6 or more (they are schooling fish and do best in numbers)

Substrate: Fine sand is strongly recommended to protect their sensitive barbels.
Aquascape: Driftwood, plants, and shaded areas help replicate their natural environment.

Water Parameters

• Temperature: 72–79°F (22–26°C)

• pH: 5.5–7.0 (slightly acidic preferred)

• GH: 2–8 dGH

• KH: 0–4 dKH

• Ammonia/Nitrite: 0 ppm

• Nitrate: Below 20 ppm

They prefer clean, well-oxygenated water with stable conditions. Regular water changes are key to keeping them healthy and active.

Tank Mates

Because of their peaceful nature, Adolfoi Corys pair well with:

Great companions:

• Small to medium peaceful tetras

• Rasboras

• Dwarf cichlids (Apistogramma types)

• Peaceful gouramis

• Other Corydoras species (if tank size allows)

• Small plecos

Avoid:

• Large aggressive cichlids

• Fin-nipping species

• Very large predatory fish

• Rough substrate environments

Feeding

Adolfoi Cory Catfish are omnivores and should be fed a varied diet:

• High-quality sinking pellets or wafers

• Frozen or live foods (bloodworms, brine shrimp, blackworms)

• Occasional vegetable-based foods

They are not “clean-up fish” — they require dedicated feeding to thrive.
