Don't use a catemacho if you want a red head kamfa use a regular fene or a redhead. Classics are made with multispecies redhead crosses sometimes included brehedori.
If this cross was the other way around m/f you would get some wierd kirins, not sure if you would from this cross though, but you may get some bonsai.
with a fh without kok you will most likley get fish with a notch in the forehead instead of kamfa shape.
I had a catemacho female pair with a classic kamfa male, but I lost interest as they could not make much but white kamfas, look like a white midas the wrong shape.
if you want classics get a line bred redhead with not much other colors.
