Calvus or Comprissiceps?

[PumaWard]

How would you tell the differences between Altolamprologus calvus and Altolamprologus comprissiceps at 1"-2" size?

the comps have more of a hook to their mouths than the calvus...

the comps also get larger, also note the different shape of the head...

Thanks :)

I think I have calvus's then, as their faces were pretty straight. They were sold to me as comps, but I was suspicious that they weren't them even before I bought them.

Again, thanks :)
