First of all, this is a fantastic site and forum

I am new on this site and this is my first topic, so be nice, please.

I recently bought 11 wildcaught Corydoras from my local fishstore, 7 males and 4 females. He had ordered them home as C. elegans, but he told my that they are obviously not, but endeed from the "elegans" complex. He also told me thet they are from Peru, and that's my second clue.
I was wondering if somebody on this site could help me identify this fish.
Some pictures showing the mentioned fish.
I hope this works!
