I got these corydoras at petco about two years ago, and wanted to get one or two more to fill out the shoal. I thought they were paleatus but I see some long dorsal fins and now I can’t be sure.

Can anyone tell either way if these fellas are corydoras paleatus or corydoras longipinnis?

I've understood that C.longipinnis quite recently got its own name and before is used to get the "longfin" into C.paleatus.

Nowadays we'd call that crossbreeding, but that wasn't before the new naming.

So they could be C.paleatus with C.longipinnis gens in them. Yours indeed seem to have slightly higher dorsals.

Logic tells me your source (Petco) won't have had wildcaught C.longipinnis and only the cheaper tankbred C.paleatus available.

So my guess is C.paleatus with C.longipinnis-blood.

I didn’t realize tank bred corydoras are cheaper/more readily available. That certainly skews things toward paleatus! Thanks for the input - I’ll be less picky when they get paleatus in at the lfs
