Pygmy Corydoras are the perfect nano cory for small tanks. Most only grow to about ¾ of an inch, which makes them ideal for aquariums as small as 5 gallons. Like all corydoras, they enjoy being in groups of 5 or more, but their small size makes them easier to keep in smaller tanks compared to other species. While pygmy corys sometimes get a bad reputation for being hard to keep, that’s usually due to poor import practices. Thanks to our quarantine process, we consider Pygmy Corydoras beginner-friendly and a great choice for new hobbyists.
Pygmy corydoras are considered a dwarf species of cory. They grow to about 40% the size of most other corydoras, with adults reaching around ¾ of an inch. Males tend to stay even smaller than females. The only other cory species that’s similar in size is the Corydoras habrosus, which you can check out here.
We’ve had pygmy corys breed naturally in our aquariums, especially when using Java Moss or spawning mops. With a little effort and stable water parameters, breeding them can be fairly easy. A few local hobbyists use marbles in place of substrate to protect eggs from getting eaten. If you're looking for a beginner-friendly breeding project, pygmy corydoras are a great fish to start with.
At Flip Aquatics, we feed our pygmy cory’s a variety of foods including:
All fish orders are covered by our 100% Live Arrival Guarantee. Shop worry-free knowing your fish will arrive healthy or we’ll make it right.
You can comfortably keep 10 pygmy corydoras in a 10-gallon tank. If you're an experienced hobbyist, it's possible to keep up to 20, as long as you maintain healthy water quality with nitrate levels below 40 ppm. Adding live plants can help with nutrient control and overall tank balance.
Pygmy corydoras don’t eat enough algae to be considered good algae cleaners. However, they are excellent scavengers. They sift through the substrate for leftover food and debris, which can help reduce waste that might otherwise lead to algae growth.
Pygmy corydoras are not fully nocturnal, but they will scavenge during both the day and night. They often school during the day, especially when kept with other similar schooling fish like otocinclus. You can often find them resting on sand or perched on plant leaves.
With proper care, pygmy corydoras can live 3 to 5 years. Keeping stable water parameters is key to their long-term health. We recommend a balanced diet of frozen foods along with veggie-based flakes or small pellets.
