At a glance the quick version
Looks how to spot one
Armoured catfish (bony plates, no scales)
A large cory with a bold pattern of dark blotches and bands over a lighter body, giving a checkerboard look. Mature males are especially striking, with a pale gold stripe on the forehead, crisp spotting on the head and short bristles on the cheeks that look like a beard; their dorsal and pectoral fins also grow longer. Females are plumper and slightly larger.13
Personality what they are like
Peaceful toward other fish, though adult males claim territories and spar with one another. In a smaller tank it is best to keep a single male with several females.1
Daily activity how busy a day looks
An active forager that roams the bottom; its bigger size means it needs a long footprint with plenty of open sand.13
Grooming and care the hands-on bits
Provide clean, well-oxygenated, slightly cool water with regular partial changes, and a soft sand substrate for foraging.1
Home where they are happiest
A tank with a base of at least about 120 x 45 cm is recommended. Seriously Fish suggests 16 to 24 C, pH 5.5 to 7.5 and 1 to 12 dGH; FishBase and Wikipedia allow up to about 28 C and pH 6.0 to 8.0.123
Food basics what goes in the bowl
An omnivore that takes sinking dried foods along with small live and frozen items such as bloodworm; give it dedicated meals rather than leftovers.1
Company who they like around
Females live together happily; males are best kept one per tank unless the aquarium is large enough for each to hold its own patch.1
The story where it all began
French naturalists Quoy and Gaimard described this fish in 1824, making it one of the earliest known corys. It spent many years as Corydoras barbatus before Britto moved it to the revived genus Scleromystax in 2003.31

Owner questions the things everyone asks
How often should I feed my Banded Corydoras?
Feed your Banded Corydoras small amounts once or twice daily. Furry Diary's starting plan suggests daily feeding. Use sinking dried foods and small live or frozen items.1 Furry Diary plan
What does a Banded Corydoras eat, and what should it never eat?
It eats sinking dried foods along with small live and frozen items like bloodworm. Avoid giving leftovers or foods that don't sink; for specific foods to never offer, ask a vet or good breeder.1
How much space does a Banded Corydoras need?
Your Banded Corydoras needs a tank with a base of at least 120 x 45 cm, with plenty of open sand for foraging. This active bottom dweller appreciates a long footprint.1
What temperature, light or water does a Banded Corydoras need?
Keep water temperature between 16-24°C (up to 28°C is tolerable), pH 5.5-7.5, and soft to moderately hard. Provide clean, well-oxygenated water with regular partial changes; moderate lighting is fine.123
How often should I clean a Banded Corydoras's home?
Furry Diary's starting plan recommends a 25% water change weekly, cleaning the glass weekly, and rinsing the filter in old tank water monthly. Regular partial changes keep the water clean. Furry Diary plan
Can a Banded Corydoras live with others?
Yes, it's peaceful with other fish. Females live together happily, but keep only one male per tank unless the aquarium is large enough for each to have its own territory.1
How long does a Banded Corydoras live?
Lifespan varies depending on care; ask a good breeder or vet for typical longevity.
Can I handle a Banded Corydoras?
It's best not to handle your Banded Corydoras; it's a delicate bottom dweller with bony plates. If you need to move it, use a container and consult a vet.
