Corydoras Adolfoi

Corydoras Adolfoi


    Adolfoi cory are a smaller size, beautiful cory species that are rare to find. This species is still, sadly, wild caught most likely due to the difficulty of rearing the fry in home aquaria. However, this being said, they are a very gentle, playful species that seem to truly enjoy the company of one another and the other fish in the tank. Once you see how stunning this fish is with the orange helmet positioned perfectly between the two black stripes, one down its back and the other from the top of the head to the bottom, you will become absolutely enamored with this species as I did the first time I saw them.

    South America: Brazil, in the Rio Negro and Rio Uaupés

General Body Form:
    Standard cory shape with rounded snout. It has a black back stripe beginning at the front of the dorsal fin and continuing back to the tail, a black stripe going down from the top of its head, down past the eye and ending at the bottom. To top it all off it has a striking orange cap. This species can be distinguished from similar looking others by the orange rather than golden head cap; rounded, rather than elongated snout; and clear dorsal fin.

    This is a peaceful schooling fish. They should be kept in schools of 6 or more. The tank should be densely planted around the edges with a large swimming space available. A sandy substrate is best suited for this species, but gravel with rounded edges is acceptable as well.

    Sinking pellets, frozen bloodworms and live blackworms for the adults.

    Along banks of slow-moving rivers with sandy bottoms.

    Adolfoi cory are open water/substratum egg scatterers. They do not guard their eggs. The eggs are sticky and will be carefully placed by the female on a flat plant leaf or stone. Typically 25 – 30 eggs are deposited. This fish is easy to spawn but ensuring the survival of the fry is more difficult. The fry must be reared on micro-cultures for the first week, water hardness must be below 6° dGH, and according to “…some breeders maintain that this species must be raised with its parents or other corydoras fry in order to learn to eat prepared foods.”

I serendipitously purchased a breeding pair and they are reproducing in my fish tank. :) 42 gal bow front freshwater tank. I took no extraordinary measures and I'm average on tank maint. I'm using a Fluval 350 which is oversized for the tank.
