Any chance you have a picture if the whole clutch?
My thought was maybe the different color ones where different lines.
No clutch pics but here is a pic of a male from the same clutch I recently sold. You can see his flames are not as pronounced and more of a silvery coloring versus the high gold from the female.
I don't think you can have different lines in the offspring with this pairing but maybe you could if it was a BEL (Super Mojo) x Normal. Both Mojos could be from "different lines" then the offspring could show different traits.
