Got this fella together with some other cories a few weeks ago. It was a contaminant with a bunch of Corydoras similis. However, I can't really tell what it is...

Seems like a juli, but there's no dosal marking. Can't be a similis as the caudal and dosal fins are marked. Can't be a bondi as the lateral line is not that distinct, so it can't be a coppermensis either.
I'll see if I can get some more pictures later.
Any comments or advice is appreciated.
Thanks!
