Thanks for your opinion, Ian.
But I'm a bit confused about this species. You say that is C. stenocephalus, but, according to PC and Yutaka Yamamoto's page, this cory has no vertical lines in the caudal fin.
This is the picture in PC:
and this in Yutaka's page:
no lines in caudal fin! C. ellisae has vertical lines in tail and the same head shape according to many fonts. This is an exporter page (I don't know if they identify correctly the fish):

what do you think?
