Maybe I fail at using search functions, but I did try. I figure this might be a good thread to ask since it's already on midevil coloration.
Is it normal for creamsicle colored devils to never have a peel/fade?
Do you mean the orange and white creamsicles? Those have already faded. Fading/peeling only refers to juvrniles in gray barre color fading to orange/creamsicle/white/piebald ect.
Or is fading maybe a sign of cleaner genetics/lower F#?
Not at all. Midevils, red devils, midas all have very ever changing colors and patterns.
I got my little 1.5" creamsicle that has grown to about 4" in short time, no pattern change at all. Do creamsicle types ever change their patterns?
Yes some change their patterns greatly and some might not. I have seen orange fish with some white patches at 1" grow into complete white fish at 10" you just never know what your going to end up with as adults which in my opinion is part of the fascination of raising these great fish.
I do find midevils all over my area from baby 1" up to full grown 10" fish and all seem to be white based with different orange patterns. Have only ever seen one adult fish that was full orange as most people on here post when I first got back into the hobby and was labeled as midas.
Orange adults usually are fully orange all their lives. Or maybe had a bit black patches as it faded And faded completely orange in the end. Then again ive also seen completely orange pure midas be orange all the way to 5-6" then as they grow they develop white areas.
I'm positive i've read something about this on here before, but again my search skills leave much to be desired.
