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.

Adolph’s Cory Adolfoi Cory
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 planetcatfish.com
“…some breeders maintain that this species must be raised with its parents
or other corydoras fry in order to learn to eat prepared foods.”
