I agree with Byron. I cannot think of a cory that grows to 4 inches. There use to be a cory (Barbabus) that grows to about 6+ inces, but now is in it's own group (yours is not a Barbadus). Looks like a "False Julie", but the long snout would make it not either a true Julie or false (Trilineatus).
With the long snout, spot on dorsal fin, Lateral dots on tail, I would guess GOMEZI.
I have the "Big" Cory book ( well, actually the Callichthyidae book) by Dr. Burgess which has over 200 species, and none of them look "exactly" like yours.
But, either way---Nice fish. :thumbsup:
According to the sources, the spotting on the upper half of the two species is distinctive to each.
C. gomezi has individual "spots" whereas
C. leopardus has more of a reticulated pattern with some of the spots joined together, which is apparent here. There are also only six bands on the caudal fin of
C. gomezi; the photos here show more I think. But having said all that, if one looks at the photos on Planet Catfish for these two species, these distinctions seem to mix together from photo to photo. And PC is a reliable site, though one cannot always speak for photos anywhere.
Jessica, is that Burgess book the
Colored Atlas of Minature Catfish published by TFH? Or another? Problem with any book is that with the new species being discovered, dozens of which are not yet described and thus named, books are out of date by the time they are printed. I got the
All Corydoras Aqua-Log book back in the late 1990's, which then contained every discovered species, but I have not kept up with the supplements (you need to subscribe to the newletter to receive these) so while still a good reference it is sadly out of date with subsequent species.
