Size 60mm or 2.4" SL. Find near, nearer or same sized spp.
Identification Corydoras are identified by their twin rows of armour plates along the flanks and by having fewer than 10 dorsal fin rays. They are most commonly confused with the other genera in the sub-family, namely Brochis, Scleromystax and Aspidoras.

Similar to C. burgessi but has an orange rather than golden head cap and clear dorsal fin. Similar to C. imitator but has a rounded rather than pointed snout. Very similar to C. duplicareus but has a thinner black back stripe.
According to the description C. duplicareus has serrations on the posterior edge of the pectoral fin spine, whereas C. adolfoi does not. This, of course, is not easy to see in a normal aquarium. The best way to see if your fish have these serrations would be to place them into a shallow, preferably white, container and shine a light up from underneath. Then with the aid of a magnifying glass you should be able to see if there are any serrations or not. As a general rule C. duplicareus tends to be a little stockier than C. adolfoi and the black band is usually a little broader.
Sexing Female is fuller (when viewed from above) and larger.

Jump to next section Husbandry Information
Feeding Sinking pellets and bloodworm for adults.
Furniture Dense planting around the edges of the tank, thus providing a large swimming space. Although gravel can be used it is best to use a soft sandy substrate.
Compatibility A perfect citizen.
Suggested Tankmates Lots of other C. adolfoi! Being light in colour, this fish looks striking if kept with darker coloured fish. Small South American Characins, such as black neon or black phantom tetras. Large shoals of small mid-water fish will encourage this fish into view.
Breeding Given an adult group of at least 6 fish (a ratio of 3 males to 1 female is best), regular water changes and good diet are the prerequisites for spawning. Around 20-30 eggs are produced in clutches. They are carried by the female in a ''pouch'' formed by her pelvic fins to the underside of broad leaves or the aquarium glass and deposited carefully. Although relatively easy to trigger spawning, rearing fry appears more problematic. Attention to water quality is essential and some breeders maintain that this species must be raised with its parents or other Corydoras fry in order to learn to eat prepared foods.
