Last year I posted some pictures some Corydoras that some people thought were C. lambert and other thought to be C. ambiacus or even C-18.
They haven't grown since then (biggest one being 45 mm. SL and 56 mm. TL).
They were exported from Peru, but the actual place of capture remains unknown to me after trying really hard to get some info from the importer.
When viewed in a darker envirornment (their tank is shaded from the light beacuse they are extremely shy) they have the clear yellow patch behind the gills seen on pics of C-09 cf. lamberti, but I am unshure about the body pattern, as I've seen many varieties of C-09 on the internet lately.
For photos they were moved to another tank where they couldn't hide, or photographing them would have been impossible.
