I just spawned my mustard gas dragon HMPK with an almost HM copper female. I'm thinking I will get all Long fin (hopefully a HM or two) but colorwise? mg? copper? mix of both? Is copper dragon a possibility? Neither carry red.

Here's dad (second pic is from breeder):

If a fish as yellow or orange 1n them, they DO carry red.
You might get copper gasses, you may get dragons. You will have long finned fish, but if the female carries PK, you'll get PK fry as well.
One last, the first and the second don't look like the same fish to me, and I am not talking about the color.
Can you get a pic of your fish facing the same direection as the sellers picture?
