Hi jcorey,
Your fish definitely bear some resemblance to
, but I'm puzzled by the marking on the dorsal fins. The photos not great, but in the picture it appears the black mark extends like a distinct black bolt up the anterior edge of the fin (by the dorsal spine, and just behind). The mark goes all the way, or nearly so, to the top of the dorsal, and does not extend far back onto the fin's membrane.
By contrast, typical
C. leucomelas has a black spot which is more of a blotch on the dorsal, not extending very high, but spread out from anterior to posterior, covering much of the lower half of the dorsal fin (covering about 25%-50% of the total fin area with black).
Also on your fish, the dorsal fin black bolt appears to extend anterio-ventrally onto the body, still as a "bolt"-like shape. By contrast, in typical
C. leucomelas, the black from the fin extends onto the body like a large black diamond (almost rectangular or triangular below the dorsal).
Actually, your fish reminds me a bit of
. Unfortunately we don't have a photo of it here, but you can find one on Corydoras World, which you can find here:

I'm probably mistaken, and your fish probably is
C. leucomelas, only because it is such a common import, but from your one photo, the ID doesn't look right to me.
Cheers, Eric
