Those who have owned corydoras catfish, often known as cory catfish, may attest to their adoration. These serene fish are resilient, beautiful, and full of life. Keep your tank clean with their help. Stories of lonely corys longing for company are prevalent, and almost all cory species are best kept in schools. Keep copies in aquariums with tiny to medium-sized peaceful fish only.
A Cory: What Is It?
A catfish is known as a cory. As bottom-dwelling scavengers, they are tiny and serene. Just 161 species of coryfish exist. A tropical-climate tank of at least 10 gallons is usually necessary for these schooling fish. Whether kept alone or in a community tank, they require little attention.
Corys, like all catfish, are bottom feeders and scavengers (but they also love a feast of brine shrimp). On the one hand, that means they can help to keep your tank clean by detecting and consuming bits of uneaten food and other debris. Contrarily, storeys can be messy eaters, spewing algae and other debris into the aquarium as they burrow through the bottom. Finally, while they are a valuable member of your aquarium’s “clean-up crew,” they will require the assistance of other scavengers, such as shrimp and snails.
Twelve common species of cory catfish are presented here for your consideration.
1. The corrupt cory
One of the more well-known varieties of corys, bandit corys have a long history of trading in aquariums. Their distinctive black masks covering their eyes make them easy to spot. Regarding water temperature, bandits are more demanding than other animals.
2. Cory, Bronze
You can find bronze corys just about anywhere, much like pepper corys. Among crayfish, these two species are by far the most popular housepets. Various colour variants, such as green, bronze, albino, and black, are available for bronze corys. Although they thrive in multiple settings, they are best kept in classrooms.
3. Julii Cory
Pet stores may sell what looks like this species, but it’s usually a different deal. The three-stripe cory, its kissing cousin, is called a Julio. Unlike three-striped corys, true julis typically do not have their spots linked into lengthy chains.
4. Panda Cory
Because of their outgoing personalities, panda corys do best when kept in groups of their species. In addition to getting along with other bottom-dwelling animals, they are amiable toward almost all nonviolent creatures. You can keep pandas in an unheated tank since they like the lower temperatures. To diversify your aquarium, you can also seek out longfin panda cory.
5. Pepper Cory
Pepper corys are available at almost any pet store and are the most popular member of this family. Although they get along with most fish, big aggressive species are not something you want to keep with these gentlemen.
6. Skunk Cory
Skunk Corys are more sensitive to elevated ammonia and nitrates than other species. For this reason, they are not suggested for a fresh new aquarium. Rather, hold off on adding this species until the tank has reached maturity.
7. Three Stripe Cory
The three-striped cory, seen at many pet stores, might be a Julii Cory. The distinctive pattern of three-striped corys’ head spots, which form a continuous string and resemble a labyrinth, is easily identifiable.
8. Sterbai Cory
Like other corys, Sterbai cory are sociable and require little attention from their keepers. As they swoop along the tank bottom, you can’t help but notice the white dots all over their bodies and fins, which contrasts with their dark brown or black colouring.
9. Pygmy Corydoras
Pygmy corys are smaller than other species, growing only to about 1 inch in length, so they can be a good choice if you have a smaller aquarium. They also swim in the centre of the tank rather than the bottom, which is another way they differ from other storeys. When there are six or more of them, they thrive.
10. Albino Corydoras
Unlike other corys with dramatic colours and patterns, the albino cory is pale, ranging from pink to white. They’re great for new aquarium keepers because they’re hardy and require little attention, and they get along well with other fish because they’re not aggressive.
11. Barbatus Cory
A larger aquarium is necessary for the barbatus cory, one of the larger species of coryfish. Additionally, they are calm and social, making them ideal classroom pets. To prevent them from eating tiny shrimp, keep them with bigger ones. Males have more prominent patterns and longer pectoral fins than females.
12. Orange Laser Cory
The orange laser cory will be the focal point of your aquarium due to its striking colouration and distinctive orange stripe. This is also one of the easiest fish to care for because they don’t have complicated requirements. Additionally, they are great additions to a community tank, as are all Corys.

Characteristics and Types of Cory Catfish
Cory catfish are small, armored catfish native to South America, particularly found in the slow-moving rivers and streams of the Amazon Basin. They are part of the Callichthyidae family and are distinguished by their barbels (whisker-like structures) and bony plates covering their bodies. Cory catfish are typically small, ranging from 1 to 4 inches in length, making them suitable for a variety of aquarium sizes.
There are over 160 recognized species of Corydoras, each with its unique coloration and patterns. Some popular species among hobbyists include:
- Corydoras aeneus (Bronze Corydoras): Known for its metallic sheen, which can range from bronze to green.
- Corydoras paleatus (Peppered Corydoras): Features a distinctive peppered pattern on a lighter background.
- Corydoras panda (Panda Corydoras): Named for its black and white coloration reminiscent of a panda bear.
- Corydoras sterbai (Sterba’s Corydoras): Recognized for its striking pattern of white spots on a dark background.
Habitat and Tank Requirements
Creating a suitable environment for Cory catfish is essential for their health and well-being. Here are some key considerations for their habitat:
- Tank Size: While Cory catfish are small, they are social creatures that thrive in groups. A tank of at least 20 gallons is recommended to accommodate a small school of 5-6 Corys.
- Substrate: Cory catfish are bottom dwellers that love to sift through the substrate for food. A soft, sandy substrate is ideal to prevent damage to their delicate barbels. Avoid sharp gravel that can cause injuries.
- Water Parameters: Corydoras prefer slightly acidic to neutral water with a pH of 6.0 to 7.8. They thrive in temperatures between 72°F and 78°F (22°C – 26°C). Regular water changes and a good filtration system are crucial to maintain clean water.
- Tank Decor: Provide plenty of hiding spots using plants, driftwood, and caves. These fish enjoy a well-planted tank that mimics their natural habitat and offers places to retreat.
Feeding and Diet
Cory catfish are omnivorous and have a diverse diet in the wild, consisting of small invertebrates, plant matter, and detritus. In the aquarium, a varied diet ensures their health and vitality:
- Staple Foods: High-quality sinking pellets or wafers designed for bottom feeders should form the base of their diet.
- Live and Frozen Foods: Supplement their diet with live or frozen foods such as bloodworms, brine shrimp, and daphnia. These foods provide essential nutrients and promote natural foraging behaviors.
- Vegetable Matter: Occasionally, include blanched vegetables like zucchini and cucumber to provide fiber and variety.
Social Behavior and Tank Mates
Cory catfish are peaceful and sociable fish that thrive in the company of their own kind. They exhibit shoaling behavior, so keeping them in groups of at least five is recommended. This not only makes them feel secure but also allows them to display natural behaviors.
When selecting tank mates, consider other peaceful species that inhabit different levels of the aquarium to avoid competition. Suitable tank mates include:
- Tetras
- Guppies
- Rasboras
- Dwarf Gouramis
- Other small, non-aggressive fish
Avoid keeping them with larger, aggressive species that may harass or prey on the Corys.
Breeding Cory Catfish
Breeding Cory catfish in captivity can be a rewarding experience. Here are some tips for successful breeding:
- Conditioning: Feed the breeding pair or group a nutritious diet rich in live and frozen foods to condition them for spawning.
- Spawning Setup: Provide a separate breeding tank with similar water conditions to the main tank. Use fine-leaved plants or spawning mops where the female can lay her eggs.
- Triggering Spawning: Simulate the rainy season, which often triggers spawning in the wild. Perform a large water change with slightly cooler water to mimic rain and drop the temperature by a few degrees.
- Caring for Eggs and Fry: Once eggs are laid, remove the adults to prevent them from eating the eggs. The eggs will hatch in about 3-5 days. Feed the fry with infusoria or liquid fry food until they are large enough to eat baby brine shrimp or finely crushed flake food.
