Agassiz's Corydoras

Agassiz's Corydoras are often confused with other members of the same family because they are remarkably similar in appearance. This species is silver or transparent on the body and covered with small black spots. Some specimens also have a black band on the front edge of the dorsal fin or a splotch at its base near the back of the head. These fish can be distinguished from other Corydoras by the two rows of armored plates that run along the flanks - they also have fewer than ten dorsal fin rays.

Tank Set-up

Agassiz's Corydoras, also called the Spotted Corydoras, are native to the Amazon River basin near Brazil. These fish tend to prefer sandy substrate because gravel could damage their sensitive barbels. Tanks for this species of Corydoras should provide plenty of cover in the form of floating plants and bogwood and the lighting should be dim. These fish are very peaceful and well suited to the community tank. They are best kept in groups with at least six of their own species and tend to be more active when kept with conspecifics.


Agassiz's Corydoras are omnivorous by nature and are likely to accept almost any food they are offered. Give your Corydoras a staple diet of sinking pellets or tablets supplemented with live and frozen foods like bloodworms, Artemia and Daphnia. Agassiz's Corydoras may also accept Spirulina wafers or blanched vegetables.


Agassiz's Corydoras are fairly easy to breed in the home aquarium and should be spawned in groups having a higher ratio of males to females. These fish tend to deposit their eggs on tank glass and may eat the eggs so it is wise to remove the parent fish from the tank after spawning. The eggs typically hatch after 3 to 4 days and, once the fry consume their yolk sacs, they will be ready to eat microworms and brine shrimp nauplii.
