I can't ever see pics well in fine detail, but they look similar. You will be able to tell the differences.
Julii has more of dots even though they are somewhat elongated at the head. The False Julii / C. trilineatus has more lines
And then there is this one which looks nearly the same!!! Did you see where the Cory was supposedly caught from, could you ask if the shop keepers know?
This one is Venezuela.
Honestly if you start looking, there a great many which look VERY similar.
