Full disclosure - We are first-year breeders, so maybe the answer is just hatch more of these and we’ll eventually be able to tell the difference, but…
I see quite a few hatchlings being listed as “Disco/Fire”. I’ve read the Morphpedia pages on both genes and I know they are quite similar. However, the advice we got from a friend is just to raise+breed all our hatchlings in order to find out for sure. I’m kinda hoping someone here knows a better way to tell the difference between these two genes.
The pairing was Firefly Clown x Disco and I’ve got four hatchlings that I believe to be Pastel+ one or the other (and het Clown).
All I’ve got are single “glamour” shots of each for now, but can definitely snap more of each if needed.
