These small catfish are not just useful but also beautiful in planted tanks. They get along well with shrimp and other tank mates, making them a great choice for small setups.
Physical Characteristics of Pygmy Corydoras
Pygmy corydoras are a unique part of the corydoras species. They are small freshwater aquarium fish that stand out. Their special features make them a hit among aquarium fans.
Size and Appearance
Pygmy corydoras are small, reaching up to 3.2 centimeters long. Males are about 1.9 cm, while females are 2.5 cm. They have the classic corydoras shape but with a twist.
Unlike other bottom-dwellers, they like to swim in the middle of the tank. This adds excitement to your aquarium.

With good care, pygmy corydoras can live up to 5 years. They do well in tropical conditions. They like water between 22-26°C and a pH of 6.0-8.0.
These fish are part of the “armoured” catfish group. They have bony plates instead of scales.
Sexual Dimorphism
Telling males from females can be hard, but there are clues. Females are rounder and bigger. Knowing this is key when breeding, where 2 males to 1 female is best.
Female pygmy corydoras can lay up to 100 eggs at once. They carry 2-4 eggs in a pouch made by their pelvic fins.

Ideal Tank Setup for Pygmy Corydoras
Setting up the perfect home for pygmy corydoras is key. They love living in planted aquariums that feel like their natural home. A 10-gallon tank is the smallest size needed for 8-12 pygmy corys. This size gives them enough room to be active.
The right substrate is important for their comfort. Sand or very fine gravel is best, as it protects their sensitive barbels. Stay away from coarse substrates that could hurt them.
Planted aquariums are a great fit for pygmy corydoras. They need dense plants, driftwood, and small caves for hiding. Java moss and floating water sprite are good choices, as they can also be spawning sites. These freshwater fish like to hide among plants and tree roots in the wild.
Keeping the water right is also crucial. Pygmy corydoras like cooler water, between 72-78°F (22-26°C), and a pH of 6.2-7.4. Soft to moderately hard water, with a dKH of 2-15 (preferably below 8), will keep them healthy and happy.
Parameter | Recommended Range |
---|---|
Tank Size | 10 gallons minimum |
Temperature | 72-78°F (22-26°C) |
pH | 6.2-7.4 |
Water Hardness | 2-15 dKH (below 8 preferred) |
Substrate | Sand or very fine gravel |
It’s important to have gentle water flow for these small fish. A sponge filter with air stones is good for filtration without strong currents. Regular water changes and good filtration help keep the water quality perfect for your pygmy corydoras.
Pygmy Corydoras Care and Maintenance
Caring for Pygmy Corydoras is a rewarding experience for aquarium enthusiasts. These peaceful community fish thrive in well-maintained environments. Let’s explore the essential aspects of their care.
Water Parameters
Pygmy Corydoras prefer specific water conditions for optimal health. They flourish in temperatures between 72-78°F (22-26°C) with a pH range of 6.4-7.5. Maintain water hardness between 2-15 dKH, ideally below 8 dKH. Regular water changes are crucial for their well-being.
Parameter | Ideal Range |
---|---|
Temperature | 72-78°F (22-26°C) |
pH | 6.4-7.5 |
Hardness | 2-15 dKH (preferably below 8) |
Feeding Requirements
Pygmy Corydoras are omnivorous, enjoying a varied diet. Offer high-quality flakes, pellets, and frozen or live foods. They particularly relish brine shrimp and bloodworms. Feed small portions multiple times a day to mimic their natural grazing habits.
Tank Mates and Compatibility
As schooling fish, Pygmy Corydoras thrive in groups of 8-12 individuals. They make excellent tank mates for other small, non-aggressive species. Their peaceful nature allows them to coexist harmoniously with various community fish.
Create a suitable habitat by using fine sand substrate and providing gentle water flow. These tiny treasures prefer dim lighting and appreciate access to the water surface for occasional air gulping. With proper care, these charming fish can live up to three years, bringing life and activity to your aquarium.
Breeding Pygmy Corydoras in Captivity
Breeding dwarf corydoras is a rewarding hobby for those who love freshwater aquarium fish. These small catfish, about an inch long, need specific conditions to breed in captivity.
To encourage breeding, create a mature 10-gallon tank. It should have lots of plants and mulm. Keep the water’s pH between 6.4-7.5, temperature at 72-78°F (22-26°C), and water softness moderate. A group of 8-12 Pygmy Corys is best for breeding.
Females lay single, sticky eggs on java moss or plant roots during spawning. The eggs hatch in 2-5 days. The fry need special care. Feed them infusoria or crushed flakes like Hikari First Bites until they can eat other foods. Regular water changes are key for their growth.
Juvenile Pygmy Corydoras develop black markings in a month. By six weeks, they show adult colors. As they grow, introduce them to a varied diet of carnivorous foods like brine shrimp, blood worms, and sinking pellets.
“Breeding Pygmy Corydoras is a delicate process, but with patience and proper care, it’s possible to raise a new generation of these charming little catfish.”
Remember, successful breeding depends on a stress-free environment that mimics their natural habitat. With the right conditions and care, you can enjoy raising these tiny treasures in your home aquarium.
