Cory ID please

[fishmomma]

I picked this pair up a few weeks ago under the name Punctatus Corys. Wondering if that is indeed what they are or something else?

And bought this pair as Julii corys. These are not the best pictures but hope they will do.

The 2 in the first pic look like 2 different species to me due to the different dorsal markings and the head shape. The one at the back looks like Leucomelas which is often mis-sold as Punctatus, the one at the front may be Melanistius.

Puncatus is as rare as Rocking horse doo doo in the hobby yet lots of spotty corys often get labled as such.

I was thinking they were two different species too! I'll try to get a full body shot of the one behind to get a better ID. Thanks!
