So these are dupilcarius or adolfi?

They are neither. They are corydoras sp. C121... They are closely related to Adolfi, except for the characteristic brown patch on the gill plate.

keep them in warm water. then do cold water changes. it makes them breed. they'll start chasing each other around and laying eggs on the glass.

from the top view. females are bigger and broader in body size. as the male are more slender.

These guys actually didn't seem to respond much to the cold water changes. I finally just ended up taking the temp down to 75 and leaving it. What they did seem to respond to was live food, in this case black worms. I also had a lot of flow in the tank via a powerhead, and then removed it, which seemed to excite them as well.
You're spot on about sexing them.
 
Cool Clockwork! I learn something new everyday. Had no idea these Panda Corydoras are also assigned as an alphabet such as pleco L numbers. These are Pandas right? Excuse me if this is a newbie question.

You are right, corys are assigned C numbers like plecos. However, these are not panda corys. These are Corydoras sp. C121, they don't actually have a species name, like panda corys which are Corydoras panda, or bandit corys are Corydoras metae.
These don't have a species name because they haven't yet been classified as a certain species by scientists. This often happens in the fish trade because more fish are discovered and brought into the hobby faster than scientists can classify them. You see it a lot with cichlids especially.
So until that happens they are just designated as an sp. and in this case they are sp. C121.
They may very well be designated as a new species in the future, or perhaps a variant of a current species. They are very very similar to Corydoras adolfi, but the brown patch on their gill plate makes then distinctly different.
 
i love corydoras, even the boring bronze ones are fantastic little guys. I've got about 5 of the bronze ones and let me tell you they're tough as old boots, survived a lot of bashing etc. really considering breeding some rare C's if i can find any in Australia. super easy to spawn, great fish to watch :) grats on them breeding
